The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

You may proceed in the direction that a green arrow signal is pointing if you are in the proper lane, regardless of any other signals that are displayed. Before turning, you must yield the right-of-way to pedestrians and vehicles already within the intersection.

After a collision, if no one has been injured or killed and you can safely do so, you should move your vehicle out of the traffic lane.

When a vehicle makes a turn, the rear wheels follow a shorter path than the front wheels. The longer the vehicle, the bigger the difference between the paths of the front and rear wheels. Therefore, long trucks often have to swing wide to complete a right turn.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

Drivers should be alert to the presence of crossing guards when near a school and must always obey their instructions.

A steady green traffic light indicates that the driver may continue through the intersection. The driver should yield to traffic or pedestrians already in the intersection and proceed when the intersection is clear.

If you experience a sudden tire blowout, do not panic. Grasp the steering wheel firmly and take your foot off the accelerator to allow the vehicle to roll to a stop. Lightly apply the breaks when it is safe to do so. Do not move to the shoulder of the road until the car has slowed considerably.

You should always change lanes gradually and carefully. Only change lanes when necessary. Every lane change increases the possibility of a traffic accident.

Warning signs are usually yellow with black markings. Warning signs may alert drivers to areas where animals, people, and vehicles are likely to cross traffic.

A driver should watch beside, ahead, and to the rear of their car. To be a good driver, you must know what is happening all around your vehicle.

When driving on an interstate highway, the speed limit is 65 miles per hour. If a different speed limit is posted, follow the posted speed limit.

Do not turn into an exit lane at the last moment. If you pass the exit you wish to take, you must go to the next one.

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.

Warning signs are usually yellow with black markings. This sign indicates that the road ahead will turn sharply to the right and then sharply to the left.

Alcohol takes effect quickly and is slow to leave your system. Cold showers, black coffee, and exercise will do nothing to reduce a person's blood alcohol content (BAC). The only way to lower your BAC is to wait.

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.

To avoid the need for last-minute braking or turning, consistently watch the road far ahead of your vehicle. By looking ahead and being ready to stop or change lanes if needed, you can drive more safely, save fuel, and help keep traffic moving at a steady pace.

When changing lanes, glance over your shoulder to check for traffic in your blind spot. You may need to look several times before changing lanes. You must keep track of what traffic is doing in front of you as well as what traffic is doing in the lane next to you.

Bicycles do not have turn signals so bicyclists use hand and arm signals to alert other drivers to their intentions. If a bicyclist puts their left arm straight out, they are signaling that they intend to turn left.

If your vehicle leaves the roadway, hold the steering wheel firmly, release the gas pedal, and gently apply the brakes. Wait until your speed has reduced, check the traffic, and look for a place to safely return to the roadway by merging back into traffic. Overcompensating by jerking the wheel to return to the roadway can cause you to lose control of your vehicle or may cause your car to go into other lanes of traffic.

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.

When changing lanes, you must be sure that there are no vehicles in the space you want to enter. Check for other vehicles behind and to the side of your vehicle by checking your mirrors and blind spots. Always use the proper turn signal before changing lanes to allow surrounding vehicles time to react to your movements.

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.

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.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must yield the right-of-way to a pedestrian with a guide dog or a white cane.

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

A distraction when driving is anything that takes your attention away from driving. Driver distractions may occur anytime and anywhere. Distracted driving can cause collisions, resulting in property damage, injury, and death.

Warning signs are usually yellow with black markings. This sign warns drivers that the roadway will be slippery when wet and they should reduce their speed accordingly.

You should enter a freeway at or near the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

On cold, wet days, shaded spots on a roadway can become icy. Shaded areas often freeze before, and thaw out after, the rest of a road.

Diamond-shaped signs are used to warn of actual or possible hazards. The color orange is used for warning signs usually found in construction or maintenance areas.

This sign is placed on roads near schools to warn drivers to slow down, drive with caution, and watch for children.

When parking downhill, turn your front wheels toward the curb or edge of the road. When parking uphill on a road without a curb, turn your wheels toward the edge of the road. When parking uphill on a road with a curb, you must turn your front wheels away from the curb.

At an intersection where traffic is not controlled by traffic signal lights, drivers are required to yield the right-of-way to pedestrians within any crosswalk, marked or unmarked. Even if there is no crosswalk, yield to the pedestrian.

A reflective orange triangle on the rear of a vehicle means it travels only at slow speeds. You may see this sign on roadwork equipment, farm vehicles, or horse-drawn wagons and carriages. It appears as a solid orange triangle during the day and a hollow red triangle at night.

Use high beam headlights only when driving in rural areas and when other cars are not nearby. Lower your headlights to their low beam setting when you are following closely behind another driver.

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.

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.

Solid yellow lines on two-lane roads indicate zones where passing is prohibited. If a solid yellow line appears next to a broken yellow line, drivers in the lane nearest to the solid yellow line may not pass. In some instances, both yellow lines will be solid, indicating that it is not safe to pass from either direction.
