Nevada CAR DMV Practice Test 22

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

When heavy rain reduces visibility, reduce your speed. Turn on your headlights so other drivers can see your vehicle. If the rain is so heavy that you are unable to see clearly, drive onto the shoulder and stop until the rain lets up.

Consuming any type of alcohol can have negative effects on your reflexes and judgment. It does not matter which type of alcohol is consumed, only how much alcohol has entered a person's bloodstream.

Regulatory signs display laws that drivers must always obey. Right turns are not permitted where this sign is present.

Signs providing information about destinations are green with white letters or symbols.

Drivers must always yield the right-of-way to a pedestrian when the pedestrian is a blind person who is using a white cane or guide dog.

You must slow down as you approach an intersection controlled by a yield sign. Yield the right-of-way to pedestrians and traffic by coming to a complete stop, if necessary. If it is safe to do so, you may proceed past a yield sign without first coming to a complete stop.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

This sign indicates that the road ahead curves to the right.

Many kinds of drugs can impair your ability to drive. This includes illegal drugs and legal prescription or over-the-counter medications. It can be a criminal offense to drive while impaired by any drug.

Decrease your speed as you approach an intersection with a yield sign. Prepare to stop and yield the right-of-way to vehicles and pedestrians in the intersection or crossroad. You must come to a full stop at a yield sign if traffic conditions require it.

Drive below the posted speed limit when safety demands it. Some traffic, weather, or visibility conditions may require you to drive as slowly as 10 miles per hour.

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.

Special child seats are available for children who are too small to wear regular safety belts. No person is strong enough to safely hold onto a child of any size during an accident or sudden stop. Never allow a child to ride in a vehicle unless they are properly fastened into a seat.

Painted curbs indicate parking restrictions. When a curb is painted white, it indicates that only short stops are permitted.

These signs indicate that the road curves to the right ahead and that drivers should slow down to the safe speed indicated (in this case, 35 mph).

Consuming even a small amount of alcohol will impair your vision, judgment, concentration, and coordination.

If stopped by law enforcement, you should stay in your vehicle with both hands clearly in sight on the steering wheel.

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

If a green arrow turns into a solid green light, you may still turn in the direction that the arrow was pointing but you must first yield to pedestrians and oncoming traffic.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

Flashing red lights are used at dangerous intersections. Treat them like stop signs.

When approaching an intersection with a solid yellow traffic light, slow to a stop before entering the intersection, if it is safe to do so. If you can't stop safely, drive carefully through the intersection.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that the divided highway is about to end.

As speed increases, the chance of a fatality increases. If you are moving faster than 80 miles per hour, you have almost no chance of living through a crash. Driving more slowly than other traffic can also be dangerous because other motorists may become impatient and make dangerous moves to pass you.

Stop lines are solid white lines painted across traffic lanes at intersections and pedestrian crosswalks. They indicate the exact location at which approaching drivers must stop.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

If an aggressive driver cuts you off on the roadway, stay calm and get out of their way. Trying to get even with an aggressive driver risks escalating the situation and increasing the danger.

Painted curbs indicate parking restrictions. When a curb is painted yellow, it indicates the presence of a loading zone, or another parking restriction.

A flashing yellow traffic light at an intersection indicates that drivers must slow down, proceed with caution, and be prepared to stop.

Most signs in work areas are orange and diamond-shaped, although some signs are rectangular. These signs and traffic control devices are commonly reflective to better attract your attention at night.

Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

You should always reduce your speed and use extra caution when children are in the vicinity. They may fail to understand the danger and may run out in front of you without looking.

It is important to stay alert on highways and be ready to react to unexpected hazards. To avoid "highway hypnosis," you should avoid looking at any one thing for more than a few seconds.
