When being passed, you must yield to the passing vehicle and not increase your speed. Allow the vehicle to safely merge back into your lane.

Airbags are important safety devices that provide protection in crashes. For best protection, a vehicle's lap and shoulder belts should be used in combination with airbags.

This sign indicates that turns in the direction of the arrow (in this case, to the right) are prohibited.

Warning signs alert drivers to upcoming hazards and are usually yellow with black markings. This sign warns drivers about potential traffic merging into their lane from the right.

If you experience a tire blowout, you should ease your foot off the gas pedal, keep a firm grasp on the steering wheel, pull safely off the roadway, and check the tires. You should not brake suddenly.

You should always dim headlights when following a truck at night. Bright lights will blind the drivers of large vehicles when they reflect off the large side mirrors.

This orange warning sign tells drivers that an area of roadwork is upcoming. When traveling through a work zone, stay alert for temporary traffic control devices.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

Alcohol is the number one killer on American roadways. Alcohol affects a person’s vision and slows their reaction time, so it takes longer to act in an emergency. Alcohol affects a person’s driving even if they are below the level of illegal intoxication.

You may be arrested, imprisoned for up to five years, or have your driving privileges suspended or revoked for 12 months if you sign a driver license/ID card application that includes false information.

At a four-way stop, you must yield the right-of-way to drivers who arrived before you. Wait your turn to enter the intersection.

Stopping distances are longer and crashes are more severe when traffic travels at higher speeds.

This sign indicates that a stop sign is ahead.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).

If a driver refuses to submit to chemical testing, driving privileges will be suspended for one year. If a driver under age 21 refuses to submit to testing, their driving privileges will be suspended for 6 months.

Although there may be enough room in the traffic lane for an automobile and a motorcyclist, a vehicle driver should remember that the motorcyclist needs the room to maneuver safely and is entitled to the entire lane. A vehicle driver should not share the lane with motorcyclists.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

It is illegal to cross the centerline to pass when driving on hills, in curves, and in other locations where you cannot see ahead far enough to pass safely. You may not pass at street crossings, at railroad crossings, where signs indicate no passing zones, or where a solid yellow line is next to your lane. You may not pass when the vehicle in front of you has stopped for a pedestrian or when driving in work zones where passing would be hazardous.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

When driving, do not develop a fixed stare. Frequently check your rearview mirrors so you know the positions of vehicles near you.

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

This sign warns that there is a flag person ahead. Always follow directions given by a flagger. Flaggers normally wear orange or yellow vests, yellow-green shirts, or bright jackets. They use paddles and red flags to direct traffic through the work zone and to let workers or construction vehicles cross the road.

If a vehicle skids while hydroplaning, the driver should try to regain control of the vehicle. If that is not possible, the driver should release the accelerator and ride out the skid. The driver should not immediately apply the brakes.

Not getting enough sleep is a cause of poor driving behavior. Just like drugs and alcohol, sleepiness slows reaction time, decreases awareness, and impairs judgment.

Warning signs are usually yellow with black markings. These signs alert drivers to areas where bicycles may be crossing.

To stay aware of hazards, you should scan the road and check your rearview mirrors every two to five seconds. Constantly staring at just the road ahead of you is dangerous. If you must drive in foggy conditions, you should use your low beam headlights, not your high beam headlights.

When stopping your vehicle on the roadway, first check your mirrors for traffic. Be aware of surrounding drivers as you release the accelerator and allow your vehicle to slow. Move your foot to the brake pedal and press with steady pressure for a smooth stop.

If the headlights of an oncoming vehicle are blinding, glance toward the right edge of the road instead of looking directly ahead. This should keep your vehicle safely on the road until you pass the oncoming vehicle.

This sign warns that the road ahead becomes slippery when wet.

Orange is the standard color for work zone activity. If you see orange signs, cones, or barrels while driving, stay alert and be prepared for unexpected driving conditions. This sign alerts drivers to an upcoming flagger whose directions should be obeyed by all drivers.

Regardless of the posted speed limit, weather and traffic conditions may make it necessary to drive more slowly. A driver must take care to slow down when approaching and crossing an intersection, going around a curve, approaching the top of a hill, or traveling on a narrow and winding roadway. A driver must be aware that there may always be dangers present due to pedestrians, traffic, weather, mechanical problems, or road conditions.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that the roadway is slippery when wet.

A three-sided yield sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. In this case, you do not have the right-of-way.

At a railroad crossing marked with this sign, a driver should look both ways, listen for any trains, and be prepared to stop if any trains are nearby. Never try to outdrive an oncoming train.

This sign indicates that a divided highway begins ahead.
