Nevada CAR DMV Practice Test 3

Work zones are often stationary, but they may also be present in the form of moving vehicles striping lines, mowing, or removing snow. Work zones are marked by orange signs with black lettering or symbols. Slow down and pay extra attention when approaching or driving through a work zone.

You cannot enter an intersection if traffic is backed up on the other side and you cannot get completely through the intersection. Wait until traffic ahead clears so you do not block the intersection.

This type of triangular sign means drivers must yield. You must slow down as you come to an intersection marked with this sign and be prepared to stop. Let any other vehicles, bicyclists, or pedestrians pass safely before you proceed.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that they are approaching a T intersection and should prepare to turn either right or left.

In rainy conditions, you should use your low beam headlights.

The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that there may be pedestrians crossing the road ahead.

You should use your low beam headlights when driving in fog. High beams will reflect back at the driver and lower visibility.

Crashes often occur when one driver does not see another vehicle or when a driver does something unexpected. Communicate with other drivers on the road to help prevent traffic crashes.

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.

This sign marks a high occupancy vehicle (HOV) lane. HOV lanes are reserved for use by buses and vehicles with a driver and one or more passengers, as indicated on the sign.

Alcohol is a depressant that negatively affects judgment, vision, concentration, understanding of reality, and reaction time. It is never safe to consume alcohol in any amount before getting behind the wheel of a car.

Even the most experienced drivers can be distracted while driving. A defensive driver looks out for the actions of other drivers and anticipates potential problems.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

A "No standing" sign means that you may only make a temporary stop to load or discharge passengers.

A driver must come to a complete stop and yield when a pedestrian is in a marked crosswalk. A driver must also yield to a pedestrian who is in an unmarked crosswalk on the driver’s side of the roadway when there are no traffic control signals.

A steady yellow light indicates that a steady red light will soon appear. If you are driving toward an intersection and a yellow light appears, slow down and prepare to stop. If you are already within the intersection or cannot stop safely before entering the intersection, continue through carefully.

This one-way sign indicates that traffic flows only in the direction of the arrow.

A wide variety of intoxicants can impair your ability to drive. These include all types of alcoholic beverages, illegal drugs, inhalants, and many legal medications (both prescription and over-the-counter).

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

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

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.

Do not drive in someone else’s blind spot. Move forward or drop back so that the other driver can see you.

Many over-the-counter medications can affect your ability to drive safely. If you take medication, even a remedy for colds or allergies that is not prescribed, check the label for warnings about its effects. If you are unsure, ask your doctor or pharmacist about driving while on the medication.

A bicycle is difficult to see in the dark, even when the cyclist is wearing a proper headlight and reflector. Both motorists and bicyclists should be especially alert when driving at night in order to prevent dangerous collisions.

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 are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

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

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.

Drivers should not parallel park within 15 feet of a fire hydrant. Drivers should only park where it is legal to do so and where other drivers can clearly see their stopped vehicle.

If you are stopped at a railroad crossing with more than one track, do not start moving as soon as a train passes. Wait until you have a clear view down all tracks before you start across. Even where there is only one track, do not start across immediately after a train passes; check again for another train that may be approaching.

This sign indicate that the right lane ends ahead.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

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.
