Arizona CAR DMV Practice Test 20

Driving defensively means anticipating potential errors made by others and preparing to compensate for their mistakes.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

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.

Unless there are signs prohibiting it, you may make a right turn on a red light after coming to a complete stop and waiting for other vehicles and pedestrians to clear the intersection.

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.

Drivers should not park within 50 feet of a railroad crossing. Drivers should only park where it is legal to do so and where other drivers can clearly see their stopped vehicle.

Every 0.02 percent increase in blood alcohol concentration nearly doubles a driver's risk of being in a fatal crash.

Head restraints are designed to prevent whiplash if you are hit from behind. They should be adjusted so the head restraint contacts the back of your head.

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.

Avoid "rubbernecking," or slowing down to look at collisions or anything else out-of-the-ordinary. This helps to relieve traffic congestion.

Instructions given by police officers directing traffic always override posted traffic signals and signs. Follow the officer's instructions.

Treat a flashing red traffic signal the same as you would treat a stop sign. Come to a complete stop, yield to oncoming traffic or pedestrians, and proceed when the way is clear.

A flashing red traffic light means the same thing as a stop sign. When arriving at an intersection with a flashing red light, you must come to a full stop and proceed when it is safe to do so.

The only situation where it is permitted to turn left at a red light is from a one-way road to another one-way road (unless posted signs prohibit this). Before turning, you must stop and yield to other traffic and pedestrians.

When turning, you should look to the rear and both sides of your vehicle to ensure it is safe to proceed before making the turn. Adjust your speed to safely complete the turn.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

This sign warns of a winding road ahead.

When being tailgated, create extra space in front of your vehicle and do not brake suddenly. Slow down gradually or merge into another lane to prevent a collision with the tailgater.

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.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

Bring your vehicle to a complete stop at a crosswalk to yield the right-of-way to any vehicle or pedestrian already in the intersection. You may carefully proceed if your lane is completely clear.

As daylight begins to fade, turn on your low beams to help others see you. Only use your high beam headlights in an open area where no other drivers are present.

This sign warns of the possible presence of merging traffic.

If multiple vehicles arrive at the same time to an intersection that is not controlled by signs or signals, the driver on the right has the right-of-way. Drivers should then proceed in the order that they arrive to the intersection.

While driving, you should remain aware of the actions of surrounding drivers. If you notice an aggressive driver nearby making erratic or improper lane changes, you should not challenge them. The safest way to handle an aggressive driver is to get out of their way.

At a green light, you must give the right-of-way to any vehicle, bicyclist, or pedestrian in the intersection. If a pedestrian begins crossing the street after the traffic signal light starts flashing, wait until they have crossed the street before proceeding.

If you experience a tire blowout, you should slow down gradually by taking your foot off of the accelerator. Don't apply the brakes until the vehicle has slowed considerably.

Driving more slowly than other traffic can be dangerous. Drivers behind you may become impatient and will be tempted to take dangerous risks to pass you.

You may not stop, stand, or park at a red-painted curb.
