Nevada CAR DMV Practice Test 23

Regulatory signs are often rectangular and white with black markings and are used to indicate what things a driver must or must not do in a designated area. They may display speed limits, prohibit passing or turning, or clarify any other driving regulation.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

A flashing red traffic light means the same thing as a stop sign. You must come to a complete stop, yield to cross traffic and pedestrians, and then proceed when the way is clear.

When on the road, drivers should not use cell phones, computers, or other distracting devices, except to report a crash or emergency. Your full attention should be devoted to driving.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

If your vehicle begins to leave the road, continue to drive with the wheels off the pavement and reduce your speed by gently applying the brakes. When at a safe speed, turn the steering wheel to return to the pavement. Do not attempt to force your vehicle back onto the pavement by sharply turning the steering wheel.

If you stop along the road at night, turn on your emergency flashers and leave your low beam headlights turned on. Be sure that other road users will be able to clearly see your vehicle.

This sign indicates that the road ahead will turn sharply to the right and then to the left.

Pentagonal signs indicate that you are in a school zone. Be extra alert to children and pedestrians when driving near a school.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

If you wish to change lanes or make a turn, signal to inform other motorists of your intentions. Signals should be activated at least 300 feet before you make a turn when you are driving on an open highway. When using a mechanical turn signal, continue signaling until you have completed the turn or lane change.

One strategy to avoid driving while impaired or intoxicated is to arrange for a ride home with a friend who does not drink. Drinking coffee or taking a cold shower cannot reduce your blood alcohol content or reduce the effects of alcohol. On average, it takes about an hour for the body to eliminate the alcohol from a single drink.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.

You must always yield the right-of-way to pedestrians. Be aware of the possibility that pedestrians may misjudge traffic signals and cross against a light.

You should not use cruise control when driving on snowy or icy roads. Your tires may lose contact with the road and you will no longer have control of your vehicle.

Pennant-shaped warning signs like this are only used to indicate a no passing zone.

Drivers should never park within 50 feet of a railroad crossing. Drivers should only park where it is legal to do so and where drivers from both directions can clearly see the stopped vehicle.

You must yield the right-of-way to police cars, fire engines, ambulances, or any other emergency vehicles using a siren or air horn and a red or blue flashing light. Follow any instructions given over the emergency vehicles' loudspeakers. Emergency vehicles often follow each other so you should proceed only when you are certain the way is clear.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

Your ability to handle dangerous traffic situations depends largely on searching for and identifying problems before meeting them. Looking far ahead of your vehicle does not mean you should simply stare at the center of the road. You need to continually scan the entire road, including the sides of the road.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

Never make last-minute turns. If you reach an intersection where you wish to turn but you are not in the proper lane to make the turn, drive to the next intersection and then make the turn from the proper lane.

Construction and maintenance signs are orange-colored and are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. This sign warns drivers that they are approaching a construction zone and that they should prepare to lower their speed and drive with extraordinary caution.

At intersections that are controlled by signs or signals and at intersections that are uncontrolled, the driver on the left must yield the right-of-way to the driver on the right when two vehicles arrive to the intersection at the same time.

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

If you miss your exit, you should take the next exit. Do not stop or back up on the highway, swerve across multiple lanes to try to make the exit at the last second, or cross over the median to turn around. All of these maneuvers are illegal and extremely dangerous.

Ramps and bridges are suspended in the air, causing them to become icy very quickly in cold weather. Drive with extra caution when crossing a bridge in freezing temperatures.

Work zone signs are orange and indicate that some type of work is being performed on or alongside the roadway. Be extremely careful when you see these signs.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.
