When the way is clear of traffic and pedestrians, you may go straight ahead or turn left or right where permitted. Come to a complete stop and go only when the way is clear. Flashing Yellow Light: Slow down and proceed with caution. Flashing yellow lights are found at construction areas and on some vehicles as well as at intersections.
Sometimes flashing red lights mark a railroad crossing. Sometimes there are gates or barriers. Stop and wait until the light stops and barriers are removed.
A red light with a green arrow means you may go cautiously in the direction of the arrow, yielding to all other vehicle and pedestrians. A steady yellow arrow clears the turning traffic at an intersection before the red light. A steady green arrow pointed upwards means you may go straight ahead. A steady red arrow means traffic making the turn indicated by the arrow must stop until the arrow changes to green.
Lane Use Control Lights : Special overhead lights are sometimes used to indicate which lanes of a highway may be used at certain times:.
Steady Red "X": Do not drive in this lane. Steady Yellow "X" : Clear this lane, signal is about to change to red. Flashing Yellow "X" : This lane may only be used for a left turn. Green Arrow: You may use this lane. A Stop Sign is red with white letters and has eight sides octagon.
When coming to one, stop before the crosswalk or stop line and do not cross it. If there is no crosswalk or stop line, stop at the point nearest the intersection to enable you to see approaching traffic on the intersecting roadway.
The stop must be made before any portion of your vehicle has entered the intersection. If it is a four-way stop, wait your turn. In any case you must wait until a safe interval occurs before moving.
Pedestrians have the right of way. A Yield Sign is a triangle. It is red and white some old signs may still be yellow with black letters. It means you should slow down to wait for traffic to clear on the road you are entering or crossing.
Give the right- of-way to all vehicles and pedestrians. Rectangular white signs with red or black letters contain information about traffic regulations.
You may find red with white signs at exit ramps and the beginning of one-way streets. They tell you:.
If you see police directing traffic, do as they direct. Police have authority to direct all traffic and pedestrians as needed. It is illegal to refuse or fail to obey police orders. You can lose your license for trying to flee or escape a police officer.
When police are not present, traffic signals and signs have the authority of law. It is unlawful to remove or deface traffic signs. When there are no signs, symbols, or police to tell you what to do, there are special rules to follow. Wait for pedestrians crossing the road:. Even though right-of-way rules have the force of law, a good driver never depends exclusively on them for safety.
A driver who has the right of way should use it sensibly, never insist on it. Different traffic lanes should be used for different purposes, there are correct lanes for through traffic, passing and turning. Lanes for Through Traffic: During ordinary driving, drive in the lane that has the smoothest flow of traffic - the least stopping and starting.
Smooth driving allows you to keep more distance between yourself and other drivers. It also helps save gas. If there are three or more lanes going in one direction, the middle lane, or lanes, are usually the smoothest. The left lane is for drivers who want to pass or turn left. The right lane is used by drivers who go slower or who are entering or turning off the road. If a road has only two lanes in one direction, the right lane generally has the smoothest traffic flow.
However, some roads have special left turn lanes at intersections. This helps keep traffic moving smoothly in both directions. Lanes for Passing: In general, you should pass on the left. Passing on the right can be dangerous because other drivers don't expect it.
Cars on the right side are also more difficult for a driver to see. On any section of the Maine Turnpike or Interstate that consists of three lanes in either direction, trucks, including truck tractors, but excluding pickup trucks may only operate in the two farthest right hand lanes.
Lanes for Turning: The safest way to turn is by crossing as few lanes of traffic as you can. Here are two rules to help you:. Start from the lane closest to where you want to go. If you are turning left, pull out toward the midpoint in the intersection, and wait with wheels straight until it's clear to turn.
Keep just left of midpoint as you turn. If you are turning right, start from the right lane, keeping as close to the curb as possible.
From two-way to two-way street. From one-way to one-way street. From divided to divided highway. From two-way to one-way street. Turn into the lane that is closest to the lane from which you came. On a left turn, turn into the leftmost lane going in your direction, whether on a divided highway, 2- way or one-way street. On a right turn, turn into the right lane. When making a left turn from a one-way street, you must be close to the left curb or edge of roadway.
If you need to move into another lane, move only after you have finished your turn and when traffic is clear. Don't turn the wheels before you make the turn. If you are struck from behind, you may be pushed forward into oncoming traffic. If you have already started through an intersection, keep going. If you have started to make a turn, follow through. Last second changes cause accidents. If you have made a mistake, go on to the next intersection and work your way back to where you want to go.
Solid white lines painted on the roadway separate lanes going in the same direction that have different uses. Broken lines simply indicated the lanes going in the same direction. Traffic circles or roundabouts are sometimes built at intersections of heavily traveled streets and roads. All vehicles approaching traffic circles or roundabouts must yield the right- of-way to vehicles already in the circle or roundabout unless otherwise directed by a police officer or by traffic control devices.
Traffic on a roundabout proceeds to the right around the raised center island. Raised pavement on the inside of the circle enables trucks to negotiate around the small island, while vehicles stay in the outer travel lane. At large traffic circles, called rotaries, vehicles also proceed to the right or counterclockwise around the center island at a slow rate of speed until the street desired is approached.
Drivers must yield the right-of- way to a vehicle on the operator's left. Exit from the circle or roundabout is then made by making a right turn. Extreme caution should be used when entering and leaving traffic circles or roundabouts and strict attention to highway signs and pavement markings is necessary. If you are going to be turning from a rotary circle within two exits, it is suggested that you should be in the right lane This applies unless otherwise indicated by road markings on pavement or traffic signs specifying the lane to be used.
When you park on a public road, make sure you do not get in the way of traffic. You must park parallel to the road except where angle parking lines are painted on the roadway.
Leave at least two feet between your car and vehicles parked in front or behind. If parked on the right hand side of the road, after starting your motor, look over your left shoulder not through your rearview mirror. When the way is clear give a proper signal, as you would in making a left turn, then pull slowly out into the street and get into the correct lane as soon as possible.
Do the same from left curb, except look over your right shoulder. Regardless of the type of street or position, always make sure that the lane which you are about to enter is free of traffic for a safe distance. No passenger type vehicle should carry a load which extends over the sides of the vehicle beyond the line of the fenders on the left side, or extends more than six inches beyond the line of the fenders on the right side of the vehicle.
You must not drive a vehicle if it is so loaded, or when there are more than 3 persons in the front seat, so as to obstruct your view to the front or sides, or as to interfere with your use of controls. Don't let passengers sit on the hood, roof or trunk of a moving vehicle. No person may ride in a camp trailer, mobile home, semi-trailer, utility trailer or trunk of a vehicle while it is being moved on any highway.
When a passenger under 19 years of age is transported in a pick-up truck, that passenger must ride in the passenger compartment of the pick-up truck, except, when the passenger under 19 is a:. A person driving an open vehicle, including pick-up trucks, and convertibles, may not transport a dog in the open portion of that vehicle on a public way unless the dog is protected in a manner that prevents the dog from falling or jumping or being thrown from the vehicle, except; when a dog is being transported by a farmer or farm employee who is performing agricultural activities requiring services of the dog, or a hunting dog at a hunting site or being transported between hunting sites by a licensed hunter.
The key to smooth clutch operation is learning to sense the friction point. This is the point when, as you let up the clutch pedal, the engine and the transmission engage.
As you continue to let up the clutch, you must match the forward or backward motion of the car with an increase in pressure on the gas pedal. Follow these steps to put the car in motion:. If the car jerks forward, you either released the clutch abruptly, or you pressed too hard on the gas pedal. If the car lurches and the engine stalls out, you've not fed the engine enough gas. Your selection of gears depends on the power and speed you need for various driving tasks. First gear gives the power needed to set a car in motion.
Second gear lets you go 15 to 25 mph, depending on the horsepower of the engine and on whether the transmission is 3,4, or 5-speed. You can also use second gear to start on ice or drive in heavy snow.
Third gear, in cars with 3-speed transmissions, is generally used for all speeds over 25 mph. If a car has a 4- or 5-speed transmission and a small engine, third is used at speeds up to 30 or 40 mph. Use fourth gear for driving above 35 mph on a flat roadway. When driving uphill, you may have to achieve 40 mph or more before shifting to fourth or fifth gear. There are several reasons to downshift: to gain power, accelerate, steer effectively, slowing the car on a down slope except when the road is slippery , and to slow down or stop.
To shift to a lower gear, follow these steps:. Learning to move a manual shift car forward after stopping on an uphill grade takes practice. To keep the car from rolling backward:. Most of what you do while driving is a reaction to what you see. To be a good driver, you need to see well. Seeing well means:. Suppose you are the driver looking through the windshield. You are approaching the end of the lane. If you don't change lanes soon, you may have to make a sudden lane change, or stop and wait for traffic to clear.
In order to avoid last minut moves, you need to look far enough ahead to see things early. One of the most common mistakes drivers make is looking in front of the car instead of up the road. Expert driver try to keep looking 10 to 15 seconds ahead. Looking 10 to 15 seconds ahead also helps you to control the car in another way. When you focus attention about 10 to 15 seconds ahead, it is easier to keep your car on a steady path.
Looking 10 to 15 seconds ahead doesn't mean looking at the middle of the road. It means taking in the entire scene, the sides of the road as well. Scanning the roadside helps you to see:. If you look ahead, you will be able to see important things that you can't see later on, such as someone getting into a parked car.
The car door might open again or the car might move into your lane right ahead of you. Any time you come to a place where other vehicles or pedestrians may cross or enter your path, look to the sides to make sure no one is coming. These places include: intersections, roadside areas, crosswalks, and railroad crossings. An intersection is any place where roads meet, so that one line of traffic meets or crosses another.
It includes:. Don't rely on traffic signals. At an intersection, look left and right, even if other traffic has a red light or stop sign. Someone may run either one. Make sure you have a good view. If your view of a cross street is blocked by buildings, trees, a fence or a row of parked cars, edge forward slowly until you can see.
If a line of cars in one lane is blocking your view of another lane, wait until the cars move. If you try to look by edging the front of your car into the other lane, you may get hit. Whenever there is a lot of activity along the side of the road, there is a good chance that someone will cross or enter.
Therefore, it is very important to look to the sides when you are near:. A 5-sided sign means you are in a school zone and must slow to 15 mph during recess, or when children are going to or leaving school, during school opening or closing hours an hour before and an hour after the beginning of the school day and an hour before and an hour after the end of the school day , or when school speed limit signs are flashing during school opening or closing hours.
Crosswalks Crosswalks are special areas set aside for people to cross the street. They are often marked with yellow or white lines. There may be warning signs. Most crosswalks are at intersections, but sometimes they are in the middle of a block. Be alert for school crossings in the country as well as in town.
You must stop when the school crossing guard directs you, and remember to always yield the right-of-way to any schoolchildren crossing the street. Stop lines are usually painted on the roadway at a distance from an intersection to give pedestrians a walkway in front of stopped cars. Stop your car before the painted stop lines. When turning a corner, watch for people who are about to cross the street. Remember, if you have a green light, the light may also be green for them.
You must wait for pedestrians in a crosswalk, marked or unmarked. A person who is blind or visually impaired may use a white cane as a means for safe and independent travel. This person may also be led by a guide dog. In either case, this person always has the right of way. If you see anyone in the roadway with a white cane or guide dog, stop at least 10 feet away and wait until the person is out of danger. A round yellow sign with a black diagonal cross gives warning to feet ahead of a railroad crossing.
A black-lettered white cross marks the railroad crossing and shows the number of tracks, if more than one. Check your mirror often for traffic behind you - every 6 to 8 seconds. This way you will find out if someone is following too closely or coming up too fast, and you will still have time to do something about it.
Additionally, you will know how much space you have behind the car. You need to look behind you whenever you slow down quickly, back up, or drive down a long or steep hill. Whenever you change lanes, give the correct signal and look over your shoulder in the direction you are about to move to make sure you do not get in the way of a vehicle that is already there.
Never rely solely on your rearview mirrors. Changing lanes includes:. Look in the mirrors quickly before you slow down or stop. It is very important to do this when you slow down suddenly.
Here are some situations when you need to check behind before slowing:. Backing is dangerous because it is so hard for you to see behind your car.
Whenever you have to back your car:. Because it is hard to see while you are backing, try to do as little backing as possible. Avoid backing into traffic. When you enter a driveway or parking space, back into it unless signs forbid it. That way you will be going forward when you pull out. Check your mirrors. Drivers of trucks and buses often try to build up speed so that they can make it to the top of the next hill.
If you see them early, you can change lanes. The three sections before this one tell you where to look. This section and the next three will tell you how to have a clear view wherever you are looking. By law, and for safety's sake, you must be able to see clearly through the windows, windshields and mirrors. To see clearly you should:. It is harder to see things at night than during the daytime. But you can do some things to help you see better. If a vehicle comes toward you with high beams on, and fails to dim the lights, slow down and look toward the right side of the road.
This will keep you from being blinded by the other car' s headlights. You should also be able to see enough of the edge of the lane to stay on course until the car passes. Do not try to "get back" at the other driver by keeping the bright lights on. If you do, both of you will be blinded.
If you look to the right you can see the edge of the lane. Communicating With Others. Accidents often happen because one driver doesn't see another driver. Or when one driver does something the other driver doesn't expect. Drivers must let others know where they are and what they plan to do.
This is communicating. People cannot see you unless they are looking your way. The horn can get their attention. Use it whenever it will help prevent an accident. Horns can be wrongly used. You should not use them without cause or to make an unreasonably loud noise. Tap the horn lightly, well in advance, to warn others you are there. Try to avoid using the horn around bicycles or horses because the riders may lose control if startled.
But if danger is near, don't be afraid to sound a sharp blast. If your car breaks down on the highway, make sure that other drivers can see it.
Some accidents occur because a driver didn't see a stalled car until it was too late to avoid hitting it. If you are having car trouble and have to stop:. Other drivers expect you to keep driving in the same direction. If you are going to change direction, let them know by signaling with the directional lights, or by hand. It gives them time to react. Always signal before you:. If you do not signal, other drivers will not know what you plan to do.
To make sure others do know:. Your brake lights let people know that you are slowing down. If you are going to stop or slow down at a place where another driver doesn't expect it, tap your brake pedal three or four times quickly. Signal with your brakes when you slow down:. We live in a hour-a-day, information-driven society in which instant communications are an accepted part of life.
Instant communications can make businesses more efficient, increase productivity and bring other benefits to society, including rapid response to emergencies. However, the use of communication devices in moving vehicles can distract the driver's attention from the primary task of driving and lead to crashes as critical and as devastating as those caused by impaired driving or other dangerous driving behavior.
Distracted driving may now be the single largest contributing factor to traffic crashes. According to the U. Department of Transportation, distracted driving resulted in nearly 6, deaths and more than a half million injuries in An in-cab driving study of commercial truck drivers by the Virginia Tech Transportation Institute indicated that by far the most dangerous distraction observed was texting. The study revealed that truck drivers who texted while driving had 23 times the risk of being involved in a crash or a near-crash incident.
Laws that prohibit cell phone use and texting have an impact on safety, but stopping the senseless crashes and deaths that distractions can cause is best accomplished by changing driver behavior. To manage or eliminate distractions, it's important to understand the three distinct types:.
Visual distractions that cause the driver to look away from the road and view something unrelated to driving, such as billboards, accident scenes, street signs and other external stimuli. Manual distractions in which the driver removes one or both hands from the steering wheel or other driving control to perform a non-driving task, such as eating, drinking, adjusting mirrors, tuning the radio or programming a GPS.
Cognitive distractions in which mental thoughts and feelings anger, anxiety, worry, etc. And while the news media and regulators have focused primarily on the dangers of texting and hand-held cell phone use in moving vehicles, other types of distractions are equally dangerous. Nearly all accidents involve a combination of two or even all three types of distractions!
Short glances at vehicle instrumentation, mirrors, installed communication devices, or other technology can be done safely if these scans are limited to less than one second and are related only to the driving task. In the rush to be on time for a pick-up or delivery deadline, or to get ahead of traffic congestion, don't make the sometimes-fatal mistake of attempting to multi-task behind the wheel. Properly used, cellular phones enhance driver safety and provide a mobile alert network for the community.
To help ensure car phone users drive safely, please follow the common sense advice offered below. A person who has not attained the age of 18 years is prohibited from operating a motor vehicle while using a mobile telephone or hand held electronic device. A violation of the statute is considered a traffic infraction.
A person may not operate a sound system in a vehicle on a public way at a volume that is audible at a distance greater than 25 feet and that exceeds 85 decibels or that is greater than is reasonable with due regard to the location of the vehicle and the effect on persons in proximity to the vehicle. What is a safe speed? How fast is too fast? It all depends on conditions. How fast you can drive, and be safe, depends on:. Speed limits are posted on many roads.
These limits are based on the condition of the road, how far you can see, and what typical traffic is like. Posted speed limits do not tell you at what speed to drive.
They only say you cannot go faster than the speed shown. Privacy Policy — orig. Password recovery. BusinessWorld Online. SMDC unveils housing project in Iloilo. Opportunities worth taking for young retailers at Caltex.

In this framework, we found consistent proofs linking the slowing of breath rhythm to increases in RSA Van Diest et al.
Jerath et al. He hypothesized an involvement of lungs stretch receptors i. The stretching of lung tissue in fact produces inhibitory signals, as the fibroblasts activity fosters a slow adaptation of stretch receptors and hyperpolarization currents Matsumoto et al. However, as already mentioned, the interpretation of these results is not so straightforward since very low respiratory frequencies overlap the frequency interval of LF power 0.
Subsequently, the shift toward a parasympathetic predominance is conveyed to the central nervous system via the Nucleus of the Tractus Solitarius, which sends its projection to the thalamus and limbic system via the parabrachial nucleus Streeter et al. In this framework, Critchley et al. At the same time, slow breathing techniques are necessarily driven by brain top-down processes stemming from the voluntary shift of attention toward breath monitoring aiming at the active control of breathing rhythm.
The nature of these top-down processes could be inferred from the model developed by Gard et al. Gard's model hypothesizes that yoga may involve top-down components such as attention, working memory, and executive monitoring. Brain networks associated with these functions are the central executive network, including both the dorsolateral prefrontal and the posterior parietal cortices Goulden et al.
Taylor et al. This network includes the anterior cingulate, the prefrontal and the insular cortices, areas involved in physiological self-awareness and cognitive modulation.
This hypothesis is partially supported by Critchley et al. At the EEG level, slow breathing techniques are associated with reductions in theta and increases in alpha activity.
The increase of alpha power is in line with the results described in a recent systematic review dealing with the neurophysiology of mindfulness Lomas et al. We hypothesized that the progressive sensory deafferentation occurring during slow breathing techniques induces an inward directed attentional shift allowing both alpha increase and higher DMN synchronization.
The thalamus, strongly engaged in a burst mode activity in the alpha range, impedes the expression of other pacemakers such those underlying theta rhythms.
According to this hypothesis, the deepening of meditative state allows the emergence of theta rhythm which owing to its off-periods, plays a fundamental role in altering the state of consciousness. Unexpectedly, the majority of slow breathing techniques studies did not directly investigate slow breathing techniques effects on the state of consciousness, even if its modification is considered one of the mail goals of Pranayama Iyengar, To our best knowledge, only one study analyzed breath-related alterations of the state of consciousness, but it adopted a fast breathing technique Holotropic Breathwork, Rock et al.
We speculate that the subjective experience of an altered state of consciousness depends on the rearrangement of cortical functional connectivity, in particular within the DMN, a set of cortical structures whose activity was found to be associated with altered states of consciousness induced by meditation Brewer et al.
Another neurophysiological framework explaining the link between slow breathing techniques and consciousness is related to the fine-tuning of thalamic and cortical activities exerted by the olfactory bulb. The neural patterns of this structure are modulated by the mechanical stimulation of the olfactory epithelium during nostril breathing Fontanini and Bower, ; Piarulli et al.
Moreover, as historically noted Ramacharaka, , nostril breathing is a fundamental aspect of every form of meditation. Studies on the animal model, as well as on specific Pranayama techniques, suggest that nasal breathing is able to modulate both the autonomic system and brain activity through receptors located in the superior nasal meatus, which are sensitive both to mechanical and chemical stimuli Wrobel and Leopold, ; Buonviso et al. More recently, other studies demonstrated the presence of significant oscillations at the same frequency of the respiratory rate in a number of brain cortical and subcortical areas, which disappeared after tracheotomy, and were restored, independently from thoracic respiration, by the rhythmic delivery of air-puffs into the nasal cavity.
These areas included the olfactory bulb, the piriform cortex, the somatosensory cortex, the prefrontal cortex, and the hippocampus Fontanini et al. The modulating effect of nostril breathing on the activity of the piriform cortex, amygdala and hippocampus has been unambiguously demonstrated in humans Zelano et al. Based on these evidence, a recently published study from our laboratory Piarulli et al.
Future studies should be aimed at verifying this hypothesis, possibly comparing brain activity during slow respiration when performing nasal breathing with that detected during mouth breathing. A general consideration emerging from this systematic review is the lack in scientific literature of a standardized methodology, both when considering the experimental design and the description of breathing techniques. The initial aim of this work was to conduct a meta-analysis of the existent literature, but due to the heterogeneity of the selected experimental groups, of the interventions, and of the outcomes, a statistical pooling was infeasible.
This issue was already highlighted in Gotink et al. Moreover, in order to increase methodological quality in breathing technique's research, we propose a checklist their precise description in scientific literature. Nash and Newberg have recently stated the importance of breath in every meditation technique. In their attempt to create a taxonomy for meditation, breath is the eighth point that must be described for a scientific definition of a meditation technique.
Specify if other techniques are associated with breathing e. Specify the mean breathing frequency and, if present, any significant breathing frequency variations. Specify whether during respiration the air passes through the mouth or through the nostrils both, left, right, alternate , or through both mouth and nostrils. Specify the presence and the duration of inspiration if any and expiration pauses if any. We found evidence of increased psychophysiological flexibility linking parasympathetic activity, CNS activities related to emotional control and psychological well-being in healthy subjects during slow breathing techniques.
This evidence is unfortunately weakened by the lack of clear methodological descriptions that often characterizes slow breathing techniques literature. Further studies are thus needed to unambiguously assess these links. Only few authors have attempted to systematically describe the psychophysiological effects of slow breathing techniques, and a fewer number have attempted to relate them to meditation practice. Finally, more research is needed to disentangle the pure contribution of breathing in a variety of meditation techniques.
As stated by Nash and Newberg , different methods e. We herein proposed a brief check-list that could help to improve research on this topic. In our opinion, it is possible that certain meditative practices and slow breathing techniques share, up to a point, similar mechanisms.
In addition, the role that nostrils and more specifically, the olfactory epithelium play during slow breathing techniques is not yet well considered nor understood: evidence both from animal models and humans support the hypothesis that a nostril-based respiration stimulating the mechanoceptive properties of olfactory epithelium, could be one of the pivotal neurophysiological mechanisms subtending slow breathing techniques psychophysiological effects.
