This sign is displayed on slow-moving vehicles.

If your vehicle is hit from the rear while you are in forward motion, your body will be thrown backward. Press yourself against the back of your seat and put your head against the head restraint to prevent whiplash. Maintain a firm grip on the steering wheel and be ready to apply your brakes to avoid being pushed into another vehicle.

When turning left at an intersection, yield the right-of-way to oncoming traffic and pedestrians. Once the intersection is clear and applicable signals allow, you may complete the turn.

A number of drugs can impair your ability to drive, including depressant medications like tranquilizers and sedatives; over-the-counter cough syrups, cold tablets, and allergy medications (which may contain impairing substances like alcohol, codeine, or antihistamines); and illegal drugs.

This sign marks the presence of a crosswalk. Be alert to any pedestrians that may be crossing the roadway.

Before you enter an intersection, look to both the left and right for approaching vehicles or crossing pedestrians. Look to your left a second time, as vehicle approaching from your left will be closer than those approaching from your right. Look across the intersection before you start to move to make sure the path is clear all the way through.

Fatigue causes errors related to speed and distance, increases your risk of being in a crash, and causes you to take more time to make decisions. When you are fatigued, you could fall asleep behind the wheel and crash, injuring or killing yourself or others.

This sign warns of two-way traffic.

This sign warns that two lanes of traffic going the same direction will soon merge into one lane.

Alcohol reduces all of the important abilities you need to drive safely. Alcohol goes from your stomach to your blood, then from your blood to all other parts of your body. Alcohol affects the areas of your brain that control judgment and skill.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

Legal prescription and over-the-counter drugs can impair your ability to drive, including drugs taken for colds, hay fever, allergies, or to calm nerves or muscles. It is illegal to drive while under the influence of any drug that impairs your ability to drive safely; this law does not differentiate between illegal, prescription, or over-the-counter drugs.

Any time that you merge into city or highway traffic, you should wait for a gap in traffic large enough for your vehicle to get up to the speed of other traffic.

Yellow lines separate lanes of traffic moving in opposite directions. A broken yellow line next to your driving lane means that you may pass.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

When making a left turn, you should always begin signaling about 100 feet before the turn. You should keep your front wheels aiming straight ahead until it is safe to start your turn. This ensures that you will not be pushed into oncoming traffic if another vehicle hits you from behind.

You should always slow down before entering a curve. You may not be able to see hazards ahead and braking in a curve may cause your vehicle to skid.

Before you return to the driving lane when completing a pass, be sure there is a safe gap between your vehicle and the passed vehicle. When you can see both headlights of the vehicle in your rearview mirror, it is safe to return to the driving lane.

All temporary signs in work zones have orange backgrounds with black writing and/or symbols.

The term “distracted driving” refers to driving while anything takes your eyes, hands, or mind away from the task at hand. Distracted driving is the most common contributing factor to reported traffic collisions. Distractions of any sort cause drivers to miss key visual and audio cues needed to avoid a crash.

Reserved handicap parking spaces should be used by persons with a mobility disability or other disability as defined under state law. In order to park in a handicap parking space, you must have either the appropriate license plate with the international symbol or the designated hang tag.

Tailgating is a common behavior that can lead to aggressive driving, and so it should be avoided. Drivers may face legal consequences for driving unsafely.

When parking on a hill, you should always leave your vehicle in gear or in the "park" position. If there is no curb, you should turn your front wheels so that the vehicle will roll away from the center of the road if the brakes fail. If there is a curb, the front wheels should be turned toward it (if headed downhill) or away from and gently touching it (if headed uphill).

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

You should be extra careful when turning and stopping during the first half hour of rain. At this point, the oil from cars has not yet washed off the pavement and could be forming a slippery mixture with the rain.

While airbags provide supplemental protection for adults in the event of a crash, they pose a severe safety risk for children. Anyone age 12 or under should sit in the back seat of a vehicle with airbags.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

When making a left turn, you must yield to pedestrians, bicyclists, or other vehicles moving on their green light.
