Arizona CAR DMV Practice Test 21

Night driving creates a unique set of problems for drivers. Due to the reduced visibility, it can be difficult to judge distance and the traveling speeds of other vehicles when driving at night. Drivers can see only as far as their headlights allow.

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

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.

Pavement on bridges and overpasses can become icy even when other surrounding pavement is dry. Bridges often freeze before, and thaw out after, the rest of a road.

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.

When driving a vehicle equipped with an Anti-Lock Braking System (ABS), a driver should press the brake pedal firmly when stopping on a snowy or icy surface. The ABS will pump the brakes more rapidly than a driver would be able to.

Drivers should leave a space cushion of three to six seconds between themselves and the vehicle directly ahead of them, under normal conditions. The distance should increase as speeds increase.

Always be aware of pedestrians near your vehicle. You must do everything you can to prevent striking a pedestrian, regardless of the circumstances.

Yellow lane markings indicate a separation of lanes where traffic is traveling in opposite directions. When you see double solid yellow lane markings, passing is prohibited from both directions.

Warning signs are usually yellow with black markings. This sign indicates that a divided highway is beginning and cars should keep to the right.

A flashing yellow traffic light means drivers must slow down, be more aware, and proceed with caution. Be alert to crossing traffic and pedestrians.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign is used to warn drivers about an upcoming curve to the right.

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.

Increase your following distance when it is difficult to see due to darkness. Use headlights to increase visibility, following the rules for proper use of high beams and low beams. Avoid looking directly at the headlights of an oncoming vehicle to avoid being blinded by the glare.

If you approach a stopped school bus that has its lights flashing and arm extended, you must come to a full stop and remain stopped until the signal arm is pulled back and the bus resumes motion. This law applies whether you are traveling in the same direction as the bus or if you are approaching from the opposite side of the street.

A roundabout is a circular intersection that usually does not include a traffic signal and flows in a counterclockwise direction around a central island. Motorists must enter from the right, yielding to traffic already in the roundabout, and follow the circle to the right until the desired roadway is reached.

When entering the interstate on a short entrance ramp where there is no acceleration lane, speed up only after you have identified a gap in traffic. In general, you should be stopped while waiting for a gap to appear.

If your vehicle is hit from the rear while you are in forward motion, your body will be thrown backward. Brace yourself by pressing against the back of your seat and putting 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.

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.

Drivers should check their rearview mirrors often to stay aware of the position of traffic behind them.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

If a tire blows out or suddenly goes flat while you are driving, grip the steering wheel firmly and keep the vehicle aiming straight. Take your foot off the accelerator and do not brake. Allow the vehicle to slow by itself and use the brakes gently, but only if necessary. Pull off the road when it is safe to do so.

At a stop sign, you must come to a full stop and check for traffic in all directions before proceeding.

A diamond-shaped yellow sign warns of possible danger ahead. Orange signs, which are mostly diamond-shaped, are used to warn of possible dangers in or near work areas.

Signs with a red circle and diagonal line over a black symbol indicate the the action represented by the symbol is prohibited. In this case, the sign indicates that right turns are prohibited.

This sign prohibits right turns. You cannot make a right turn at an intersection where this sign is posted.

A red arrow means "stop." You must remain stopped until a green light or green arrow appears. Do not turn against a red arrow.

A steady yellow light means that the signal is about to turn red. If the light is yellow and you have not yet entered the intersection, you should come to a safe stop. Speeding up to "beat the light" is illegal and dangerous.

You need a longer distance to stop your vehicle on a slippery road than you do on a dry road. Maintain an increased following distance when driving on slippery roads.
