Nevada CAR DMV Practice Test 20

Smoking while driving can create dangerous distractions by causing you to take your hands off the wheel and/or your eyes off the road.

Keep a space between yourself and parked vehicles. A person may step out of a parked vehicle or out from between the parked vehicles. A driver in a parked vehicle may not see you and may start to pull out suddenly.

Defensive driving is using safe driving strategies to prevent crashes. This means that you alter your driving to fit the weather conditions, the way you feel, and the actions of other drivers, bicyclists, and pedestrians.

If a yellow panel with the message "Exit only" is on a highway sign, the lane below the sign will not continue through the interchange. Instead, the lane will go off of the roadway to form a ramp. If you are in a lane directly under an "Exit only" sign, you may change lanes to move through the interchange or you must exit the highway.

At night, visibility is reduced. Take steps to make driving in the dark more safe for you and the other drivers on the road.

Drivers should not park within 20 feet of a crosswalk. Drivers should only park where it is legal to do so and where other drivers can clearly see their stopped vehicle.

This sign indicates that there is an intersection ahead. A road joins from the right.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

Drivers should always look down the road at least 12 seconds ahead of their vehicle, unless they are driving on a freeway. When on a freeway, drivers should look 20 to 30 seconds ahead of their vehicle. Looking ahead may help prevent sudden stops or turns.

Regulatory signs are white, rectangular signs with black markings. Drivers must obey the instructions posted on all regulatory signs. Where this sign is posted, it is prohibited for drivers to pass one another.

It is always unlawful to exceed the posted speed limit, even when passing another vehicle.

You should use your low beam headlights when driving in fog. High beam headlights may cause the light to reflect off of the fog and into your eyes.

Do not use your high beam headlights when approaching or following another vehicle at night. Switch to the low beam setting to ensure the safety of everyone on the road.

If you are following another vehicle at a railroad crossing, check to make sure you have enough room to get all the way across before you drive onto the tracks. You should never try to pass another vehicle as you approach or cross a railroad crossing. Always check for trains before crossing any railroad tracks.

When you hear the siren or see the flashing lights of an emergency vehicle coming from behind your vehicle, you must create a clear path for the emergency vehicle and stop. Reduce your speed and safely pull over to the side of the road. If the emergency vehicle is directly behind your vehicle when you are in heavy traffic, keep moving slowly until you can get out of its way.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

This sign warns that the road is slippery when wet.

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.

Yield the right-of-way to the driver on your right at a four-way intersection if you both arrive to the intersection at the same time. You may then proceed when it is safe to do so.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

This is a "Keep right" sign. It indicates that a traffic island, median, or barrier is ahead and that drivers must keep to the right of it.

Always signal for an appropriate amount of time before making a lane change or exiting a freeway. Before you make any move to the right or left, quickly turn your head and look over your shoulder to see if your blind spot is clear.

This sign indicates that right turns are prohibited.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

White lines are used to separate traffic moving in the same direction. Solid lines indicate that drivers are not permitted to pass.

Painted curbs indicate parking restrictions. When a curb is painted blue, it indicates a reserved handicap parking area. Only those with the proper license plate or hanging tag are allowed to park in the designated area.

Driving while impaired or intoxicated is a serious traffic safety problem. Safe driving is not possible when you drink alcohol or take other drugs. Driving under the influence is dangerous both to you and to others on the road.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers about an upcoming steep hill. They should adjust their speed accordingly to avoid brake damage or collision.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

Always stop before entering the roadway from a driveway and yield to any approaching vehicles or crossing pedestrians. The stop should be made before crossing the sidewalk area. Failure to stop is unlawful.

Whenever you park, always turn off the engine and set the parking brake. Take the keys and lock your vehicle. Do not rely on the transmission to hold your vehicle in place.

Warning signs that indicate approaching hazards are usually yellow with black lettering or symbols. Warning signs in work zones are orange with black lettering or symbols.
