Utah CAR DMV Practice Test 18

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

If a traffic light at an intersection is not functioning due to a power outage, yield to other drivers in the same manner as you would when approaching a four-way stop. When it is your turn, proceed through the intersection with caution.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

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.

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.

This sign warns that there is a steep hill or downgrade ahead.

If a vehicle skids while hydroplaning, the driver should try to regain control of the vehicle. If that is not possible, the driver should release the accelerator and ride out the skid. The driver should not immediately apply the brakes.

The faster you are driving, the longer it will take for you to stop to react to other drivers' unexpected moves.

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.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

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.

Warning signs advise drivers of potentially hazardous conditions. For your own safety, obey warning signs. Disregarding the information provided by a warning sign may result in an accident due to your negligence.

Your horn should be used to warn other drivers or pedestrians in situations where they may not see you. For example, if you think another driver is about to hit you, you should sound your horn.

Pedestrians have the right-of-way when crossing the road at an intersection. A crosswalk exists anywhere that two streets intersect, whether the crosswalk is marked or unmarked.

If you are on an entrance or acceleration ramp and are entering interstate traffic, you should yield to drivers already on the interstate highway. Merge safely into traffic when you are able to do so.

To check your blind spot before changing lanes, you should look over your shoulder in the direction that you plan to move.

In a situation requiring you to yield the right-of-way, you must also stop if you cannot merge safely into the flow of traffic.

Drivers must be especially careful when driving near a cyclist and should maintain a safe operating distance between their vehicle and the cyclist.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

Telltale signs of drunk driving include speeding, weaving, driving more slowly than the normal traffic flow, making jerking motions, and making quick and sudden stops.

Look over your shoulder to check your blind spot every time you want to change your vehicle's position. If you are turning, changing lanes, or pulling toward or away from a curb, you should check your blind spots.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

High speeds greatly increase stopping distances and severity of crashes. The faster you drive, the greater the impact or striking power of your vehicle, should you be involved in a collision.
