Special driving conditions

Reduced light

To the defensive driver, darkness requires even greater alertness. Reduced visibility, glare from oncoming headlights, animals crossing the road, and eye strain all combine to make night driving hazardous.Laws and guidelines for driving in reduced light include:

• Headlights must be used from one-half hour after sunset until one-half hour before sunrise and at any other time when, due to insufficient light or unfavorable weather conditions, persons and vehicles on the road are not clearly discernable at a distance of 1,000 feet ahead.
• Turn on low beams whenever the light begins to fade. It helps others identify you and judge what you’re doing.
• Never use parking lights while driving. They cannot be seen until after your vehicle is clearly visible. It is not legal to drive with only parking lights when headlights are required.
• If you cannot see clearly, it makes sense to increase your following distance at least three or four seconds.
• At night your headlights give you a clear view for only a very limited distance ahead. If you go faster than 55 mph at night, you cannot stop in the distance that you can see ahead.
• Use high beams on rural highways. Use low beams when following other vehicles, when meeting on-coming vehicles, and when driving in town. You should dim at least 500 feet (about four to five seconds) before meeting an oncoming vehicle.
• If the oncoming driver fails to dim, and you are more than 500 feet from the vehicle, use a distribution of light or composite beam high of sufficient intensity and aimed so that the glaring rays are not projected into the eyes of the oncoming driver. The low beam shall be aimed to avoid glare at all times. If you are within 300 feet from the rear of a vehicle you are approaching, dim your lights to their lowest beam.
• A clean windshield, inside and out, will help reduce the amount of glare from oncoming vehicles. Clean headlights will naturally give more light and help you to see better.
• Eyestrain, fatigue and lack of concentration can be the result of staring at the spot created by your head-lights. It may be difficult, but keep your eyes moving, especially at night. Scan for animals, pedestrians and bicycle riders. Check to the sides for lights from other vehicles that might be crossing or entering the road ahead. Constantly check the lights of vehicles ahead for any indication that they are changing speed or lane position.

Weather conditions

• Use low beam headlights. Front fog lights are some-times helpful.
• Rear fog lights (red) should only be used in heavy fog or in similar hazardous weather conditions resulting in seriously reduced visibility. Switch off your rear fog lights once visibility improves. A rear fog light gives advanced warning of your vehicle in poor visibility conditions.
• Reduce your normal speed, but be careful. The chance of a crash is extremely high whenever the difference between your speed and the speed of other traffic is more than 15 mph. Stop at the nearest safe place whenever there is potential for a great difference in speed.
• When you can’t see at least 10 seconds ahead, consider pulling off at the nearest safe spot and stopping.
• Scan ahead for taillights, headlights, pedestrians, and for stopped or slow-moving vehicles. Create as big a space cushion as possible.

Slippery surfaces

You MUST SLOW DOWN when the road is slippery, because stopping distances are increased.


•Increase your space. Double the time between you and the vehicle ahead (cars, four seconds).
•Use your headlights on low beam.
•Wait a short time after the rain starts before you turn your windshield wipers on. This will avoid smearing your windshield. Replace the blades if they smear or streak the windshield.
•Be careful during the first half hour after the rain begins. Dust and oil mix with the water and make the roadway slippery.
•Hydroplaning may occur during rainstorms. This is a condition where the tires ride on a thin film of water instead of the road. To prevent hydroplaning, SLOW DOWN.

Snow or ice

•Equip your car with snow tires or chains to prevent skidding and to reduce stopping distance.
•DO NOT change speed or direction suddenly.
•Watch for ice on bridges and in shady areas.
•Triple your space cushion ahead on snow (cars, six seconds). Quadruple the distance on ice (cars, eight seconds).
•Keep your windows clear so that you can see and communicate with others.
•Slow gradually and smoothly before stopping or turning.
•Never lock your brakes. You have no steering control unless the wheels are turning.
•DO NOT use cruise control.


•Wind can be a problem for all drivers, and is especially hazardous for trucks, recreational vehicles, campers, and drivers towing trailers. Driving at slower speeds is the best defense.
•Watch for open spaces after driving in a protected area. Be ready to make steering corrections because of changes in the wind.
•When meeting large trucks and buses, be prepared to make steering corrections for sudden changes in the wind.
•Be very alert and careful on wet or slippery surfaces.


A blizzard is perhaps the worst of all possible conditions for driving. It combines the limited visibility of fog, the slippery roads found with ice and snow, and unexpected steering corrections. Because of this, a defensive driver simply avoids driving in a blizzard, if at all possible. Listen to your local radio station for severe weather information. If you are caught driving in a blizzard and end up in a ditch, or are stranded on the road, use the following rules:

•Do not panic. Stay with the car so you can be found more easily.
•Keep a window open for a bit of fresh air. Freezing wet snow can completely seal out oxygen.
•Be aware of carbon monoxide. Run the engine and heater sparingly, and only with a window open for ventilation. Make sure that snow has not blocked the exhaust pipe.
•Do not remain in one position. Clap your hands and move your arms and legs vigorously periodically.
•Use your emergency flashers to make your car more visible to working crews. Turn on your dome light at night.
•Take turns keeping watch. If more than one person is in the car, do not all sleep at one time.
•Beware of over-exertion and over-exposure.

Emergency situations
When a crash seems imminent

Crash situations do arise. Remember these three things to make an inevitable collision less dangerous. First, slow as fast as possible and, second, turn away. Third, when appropriate, speed up.

Slow quickly to minimize impact

Pump conventional brakes for better control and steer-ing. Pushing the brake pedal too hard and steadily can cause a skid.

Anti-lock brakes adjust automatically so apply hard, steady brake pressure when using this type of braking system.

Turn away quickly

If it is not possible to avoid a collision, make sure you do not hit the other vehicle head-on. Turn away and run off the road if necessary. The rule of thumb is to turn right. If the other driver does the same, the crash may be entirely avoided. Try not to use the brakes while turning away to lessen the chance of skidding and therefore not being able to turn away.

An alternative: speeding up

Speed up to avoid a collision from the side or from be-hind if there is room to do so. Push the gas pedal to the floor, but be sure to slow once the danger has passed.

In the last short seconds, remember:

• Do not panic;
• Turn away from oncoming traffic, choosing a glancing blow rather than a head-on crash; and
• If necessary, choose to hit something that will more likely give way.

Gas pedal sticks

If your gas pedal sticks:
• Concentrate on steering (Keep your eyes on the road.);
• Try to free the pedal with your foot (If this does not work, push in the clutch or shift to neutral.);
• Use your brakes, stop at the nearest safe place and turn off the ignition; and
• Find out what caused the problem and have it repaired.


The main thing to remember in a skid is to keep calm and not overreact.

• Stop doing whatever you did to start the skid:
1. If you slammed on the brakes, ease up on them.
2. If you accelerated too fast, ease up on the gas pedal.
• Steer to keep going straight down the road.
• Be careful not to over steer. Be ready to steer in the opposite direction as your vehicle begins to come out of the skid.
• Refer to the owner’s manual for special instruction about skids when operating front-wheel-drive vehicles.
NOTE: The information above pertains to vehicles with conventional brakes. Procedures for driving vehicles with ABS braking systems are different. In an emergency situation, ABS pumps the brakes for the driver — much faster than the driver can. All drivers need to do is press down hard on the brake pedal, hold it and steer out of danger. Drivers should be aware that removing steady pressure from the brake pedal or pumping the brakes will disengage or turn off the ABS system. Make sure you are aware of the type of braking system your vehicle has.

Brake failure

If your brakes fail:

• Pump the brake pedal rapidly;
• Use the parking brake, but hold the brake release so you can ease up on the brake if the rear wheels lock and you begin to skid;
• Shift to a lower gear, and look for a place to slow and stop off the roadway;
• Do not try to drive the car to a garage.

Be cautious with vehicles with steering-lock devices

Never turn your ignition key to the lock position while the vehicle is in motion. That will cause the steering to lock and, quite possibly, loss of control of the vehicle.

Steering lock operation

If you have a tire blowout, you should:

•Hold the steering wheel tightly, and keep the car going straight down the road.
•Ease your foot off the gas pedal but do not hit the brakes.
•After the car is under control, brake gently, and pull off the road at the nearest safe spot.
•Use caution when changing the tire.

Oncoming car in your lane

If another vehicle is coming at you in your lane:

•Slow down and try to warn him by flashing your headlights.
•If he keeps coming, pull as far right as possible.
•If he still keeps coming, and there could be a collision, steer off the road to the right.

If an oncoming or stopped vehicle should suddenly appear in your lane of travel and there is immediate danger of a collision, STEER OFF THE ROAD TO THE RIGHT.

Wheels off the road

If you should run off the road, there are certain things you can do that could save your life:

•Do not panic.
•Grip the steering wheel tightly, and be prepared to withstand sudden shocks.
•Stay on the shoulder. Ease off the accelerator.
•Brake gently and slow gradually.
•After speed has been reduced, check behind as well as ahead for oncoming traffic.
•Turn sharply onto the pavement.

Wet brakes

Wet brakes may pull your vehicle to one side or the other, or they may not hold as well as usual. You should always test your brakes after driving through deep water. Brake gently several times until your brakes are dry and work properly.

Hazardous situations

If your vehicle is not working properly and you need to stop, you should stop with all four wheels on the shoulder. Then:

•Turn on your emergency four-way flashers;
•Get out of the side of the vehicle away from the traffic;
•To indicate vehicle problems, tie a white cloth to an antenna or door handle and raise your hood or trunk lid; and
•DO NOT walk for help if you are on the Interstate.

If you are driving and see a disabled vehicle parked on the shoulder, move to the left lane if possible. The driver might not have seen you, and may open the door or pull onto the road.

Carbon monoxide

Carbon monoxide is a colorless, odorless and poisonous gas. Signs of carbon monoxide poisoning are weariness, yawning, dizziness, nausea, headache and ringing in the ears. If you feel any of these symptoms, stop your engine and open the windows to get fresh air. To avoid carbon monoxide poisoning:

•Have the exhaust system checked regularly for any leakage;
•Avoid parking for long periods of time with the engine running; and
•DO NOT start your vehicle, or warm up the engine, in a closed garage.

Railroad crossings (highway-rail intersections)

Highway-rail intersections require special caution on the part of the driver. They are marked with advance warning signs and markings. When approaching or entering a highway-rail intersection:•Always expect a train at every highway-rail intersection;

•Do not get trapped on a highway-rail intersection. NEVER drive onto a highway-rail intersection until you are sure you can clear the tracks on the other side without stopping;
•When gates are down, realize the road is closed. Stop and wait until the gates go up and the red lights stop flashing before proceeding. NEVER drive around gates;
•Stay alert, especially when you are at a multiple-track crossing. Before crossing, look and listen carefully for another train coming from either direction;
•If your vehicle stalls on the highway-rail intersection, get everyone out of the vehicle and far away from the tracks immediately. NEVER try to start your vehicle or push it off the track with passengers inside. Call 911 to report the emergency situation;
•NEVER race a train to a highway-rail intersection. To do so is foolish. If you lose, you and your passengers may never have another chance; and
•NEVER pass another vehicle at a highway-rail inter-section.

Road construction

Special care is needed whenever the normal pattern of highway traffic is changed by construction. A flag per-son may be stationed on the shoulder of the road near the work site to protect the lives of the traveling public and the highway workers. If the flag person directs you to stop, do not proceed until you are directed to do so. Drive slowly and keep alert for workers or equipment that may enter into the traffic stream, causing you to slow or change lanes. Extra care should be maintained through construction work zones even though there is no apparent work activity in the immediate vicinity.

When approaching a construction zone, if you pass a heavy vehicle at a high speed and then cut back in front of the truck so you won’t be trapped behind it, the truck driver is forced to use emergency braking. If there is not enough braking distance between the truck and your passenger vehicle, the truck will rear end your vehicle, causing a serious or fatal crash.


Pedestrians are people who use and cross public road-ways and paths by means other than motor vehicles and bicycles. This includes, but is not limited to, walkers, joggers, skaters and people using wheelchairs.

•Expect frequent encounters with pedestrians in business districts, residential areas, school zones, park settings and shopping areas.
•In situations where encounters with pedestrians are likely to occur, slow your motor vehicle to a speed allowing adequate sight distance to respond to possible situations.
•Yield the right of way to pedestrians when driving through intersections, changing lanes or passing, turning through intersections, and when entering or leaving a public roadway.


Animals, both large and small, present a hazard if the motorist takes an action that results in losing control of the vehicle. Regretfully, the safest thing for you and other drivers that may be near you, may be hitting the animal. Concentrate on keeping control of your vehicle before, during, and after the collision.


Some persons have severe physical, mental or emotional problems that prevent them from driving safely. Other persons impose physical and mental problems upon themselves through the use of alcohol and other drugs. Although most drivers have some type of limitation, they can compensate and be a safe driver. It is important that all drivers recognize their limitations and compensate or simply not drive when they are impaired.


We have degrees of emotions. For example, we can be upset, angry or enraged. A person’s ability to control himself and drive safely is affected by the degree of his emotion. However, persons have different degrees of control. Some persons lose control of their emotions for very little reason. Whenever persons lose control of themselves while driving, they make more driving errors. These errors greatly increase the possibility of crashes.

IT IS DIFFICULT, IF NOT IMPOSSIBLE, FOR A PER-SON TO DRIVE SAFELY WHEN THEY ARE GRIEF STRICKEN, ENRAGED OR TERRIFIED. These and other deep emotions can overcome a person’s power to think clearly. The ability to identify critical objects and make sound decisions is lost. Persons tend to react to a situation rather than respond to it in a reasonable manner. Deep emotions are not turned off and on easily. Whenever anyone is overcome with emotion and not in control of themselves, they should not drive.

Even mild emotional feelings can affect your driving. Driving requires your full attention. You cannot identify critical objects and make sound decisions when your mind is occupied with something other than driving.


All drivers use their eyes to search out and identify vehicles, persons and objects that could cause them to change speed or to turn. How well they do it often depends on how well they can see. Drivers with good vision can identify critical objects sooner. Therefore, they have time to predict what could happen, decide what they need to do, and still have time to execute their decision.

Good vision means:

•seeing clearly so you can identify critical objects ahead and do something about them;
•having good side vision to alert you to objects moving in from the sides;
•being able to judge distances to enable you to make good decisions;
•being able to see clearly at night; and
•recovering your ability to see clearly after being blinded by headlights.
Persons who cannot see clearly can compensate by wearing glasses or contact lenses. Persons with poor side vision, distance judgment, night vision and glare recovery must find ways to adjust or compensate for their poor vision or STOP DRIVING.
•Drivers with POOR SIDE VISION must look to the sides by moving their head as well as their eyes. They must be especially careful to look back over their shoulder when changing lanes.
•Drivers with POOR DISTANCE JUDGMENT must allow more following distance to compensate for their inability to accurately predict what’s happening 10 to 15 seconds ahead of them. They also have to allow more distance when deciding to pass.
•POOR NIGHT VISION is a major problem. Drivers can compensate by driving at slower speeds. Driving at speeds 10 to15 mph slower than other traffic can be extremely hazardous, however. These persons should limit their driving to slower speeds on well-lighted streets or to daytime driving only.
•Persons whose eyes do not adjust quickly after pass-ing glaring bright lights have a very serious problem. Looking to the right side of the road, away from the glare, can help. The best solution is to limit driving to daylight hours only.


Hearing is more important for driving than many per-sons realize. We identify many sounds as CRITICAL. The sound of screeching tires, trains, a siren, a tap of a horn, the sound of a motor from a car in your blind spot, all could cause you to decide to change speed or to turn.

Drivers with poor hearing can learn to compensate. Hearing aids and outside rearview mirrors are often the best way to compensate for loss of hearing. Being extra alert, looking farther to the sides and using side-view mirrors are the other ways to adjust for loss of hearing.

Drivers with normal hearing may not realize they do not hear critical sounds. Many vehicles are built for quiet rides. They keep sound out and provide radios and CD players to fill your car with music. The very things that provide enjoyment prevent you from hearing critical sounds. Drivers should limit the loudness of sounds within their vehicle.

Cell phones

Cell phones are everywhere. In emergencies they can be lifesavers, and, at other times, they can simply be a great communications tool. But using a cell phone while driving is dangerous.

Federal studies have shown that using cell phones, including the hands-free variety, has precipitated many crashes and near misses. And, in fact, using hands-free cell phones provides little safety benefit over hand-held phones, according to the National Highway Traffic Safety Administration. In addition, the research shows that it is the actual process of conversing that proves to be among the greatest driver distractions.

Wyoming law prohibits reading or sending a text message from a cell phone or other device while operating a vehicle. Some cities and towns in Wyoming have ordinances against using a cell phone phone while operating a vehicle within city limits, so be sure to check ahead and watch for notifications banning use of cell phones. WYDOT recommends vehicle operators pull well off the highway and STOP before making a cellular call or texting.

Always remember, your first responsibility when you are driving is to pay attention to the road.

•If you must dial while driving on a road on which cell phone calls are allowed, dial a few numbers, look back at the highway and in your mirrors for any developing safety problems, and then dial the last numbers.
•Do not engage in extended, emotional or otherwise distracting conversations. Tell the person you will call back when it is safe to do so.
•NEVER read or send text messages on your cell phone while driving. It is illegal and dangerous and has caused numerous preventable crashes.


Some drivers have an illness, disease or a disability that may prevent them from driving safely. It is apparent that, when persons are unable to control themselves, they simply should not drive. A doctor’s advice is helpful in determining if a person is capable of driving safely. However, physical, mental and emotional conditions change daily. As a driver, you must judge your condition and decide to drive only if you are FULLY able.

Traffic signals

Red light

You must stop behind the crosswalks or stop line. You can turn right at a RED light unless there is a sign that prohibits the turn. You may turn RIGHT only after STOPPING AND YIELDING to persons and other vehicles. You may also, after stopping and yielding, turn left from a one-way street onto a one-way street.

Amber light

If possible, you MUST stop before entering the intersection. If you can-not stop safely, you should carefully go through the intersection.

Green light

You may enter the intersection when the way is clear. You MUST yield the right of way to other vehicles and persons already in the intersection.

Flashing red light

You must come to a complete stop before entering the intersection. This light has the same meaning as a “STOP” sign.

Flashing amber light

You must use caution. This light warns of a dangerous intersection or location.

Turn arrows

1. A RED arrow prohibits turning in the direction of the arrow. It is used to remind drivers that they must turn in the direction the arrow is pointing when the light turns green.

2. An AMBER arrow may appear after a GREEN arrow and warns you to clear the intersection.

3. A GREEN arrow means that you may turn in the direction shown by the ar-row without stopping if the way is clear.

You MUST yield the right of way to persons and other traffic within the intersection.

Above all else, drive safely

Welcome to the latest edition of Wyoming’s Rules of the Road driver’s manual. This book has been revised to include some of the most recent changes enacted by the Wyoming State Legislature effective July 1, 2014.

You will find information on how to obtain a driver license or ID card, the penalties for drinking and driving, requirements for insurance, what to do in the case of a crash, rules for driving on streets, highways, and railroad crossings, and other driving related subjects. You will also find information on other driver services offered by the Wyoming Department of Transportation.

Safe driving involves obeying traffic rules and regulations, being courteous on the road, driving defensively and making sure that you and your passengers wear a seat belt.

If you have any questions, don’t hesitate to contact Driver Services at (307) 777-4800 or 4810, or write to WYDOT at Wyoming Department of Transportation, Driver Services, 5300 Bishop Boulevard, Cheyenne, WY 82009-3340.

Traffic signs

The shapes and color of signs have meaning. If fading light, fog, rain, snow or darkness makes it difficult to see the letters, you should still know what to look for or what to do.

Pavement markings provide the driver with important information about the proper position of vehicles on the roadway.

Regulatory signs

These signs tell you what to do. You must always obey them.


Rectangular signs regulate traffic and direct the driver’s speed and direction.

Octagon (eight sides)

This shape is reserved for stop signs. You must come to a complete stop.

Triangle pointing down

This shape requires that you yield the right of way to cross traffic or to merging traffic.

Warning signs

Warning signs alert you to conditions ahead. They are usually diamond shaped and warn you about road hazards, construction sites, schools or other situations which require your special attention. While most warning signs are yellow, construction and maintenance warning signs are orange.


These signs are yellow with black letters. They warn of a possible danger ahead.


This sign warns of a school zone ahead or marks a school crossing. The absolute speed limit in a school zone is 20 mph.


Pennant-shaped signs are located at the beginning of a no-passing zone.


A round sign warns of a railroad crossing ahead. Instead, a stop line or an “X” with the letters “RR” may be painted on the pavement before a crossing. Or any combination of the above may warn of an upcoming railroad crossing.


Construction signs have black lettering on an orange back-ground. They warn motorists of temporarily dangerous or unusual conditions on construction or maintenance projects.

Emergency Notification Sign

The ENS (Emergency Notification Sign) is for those emergencies that would require stopping train traffic due to an obstruction on the tracks, or any other problem at the cross-ing like if the lights or gates are not working properly.

Guide signs

Guide signs are very helpful. They tell you where you are, what road you are on and how to get where you want to go. Most guide signs are rectangular. However, guide signs for county roads and route markers on freeways are different in shape. The type of information given determines the color of the sign.
