Utah CAR DMV Practice Test 20

At night, you must dim your headlights to their low beam setting when you are within 300 feet of the vehicle in front of you.

A flashing yellow light means that you should proceed through the intersection slowly and with caution. Scan your eyes across traffic in both directions.

The maximum speed limit on a rural interstate highway may be 65, 70, 75, or 80 mph. Rural interstate highway speed limits vary by location, so always be aware of the posted speed limit where you are driving.

Double solid lines indicate that you may not pass or change lanes. You cannot cross the lines unless it is to turn left to enter or exit a highway, to turn into or from a driveway, or to make a U-turn (where permitted).

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.

If you encounter an aggressive driver, you should make every attempt to get out of their way. You should avoid making eye contact with a hostile driver. Challenging a hostile driver by speeding up may only make them angrier, thereby increasing their danger.

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.

It is unlawful to drive at night using only your parking lights. You must use your headlights when driving in lowered visibility.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

White lines are used to separate traffic moving in the same direction. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

You may practice driving with a valid learner's permit only if you are accompanied by an approved driving instructor, parent, or legal guardian. A responsible licensed adult who has signed for financial responsibility may also be allowed to supervise a learning driver.

You must always bring your vehicle to a complete stop and yield to approaching traffic before proceeding past a stop sign. Don't feel pressured by surrounding traffic to avoid making a complete stop.

If two vehicles arrive at the same time to an uncontrolled intersection, the driver on the left must yield to the driver on the right. The driver on the left may then proceed when it is safe to do so.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. Continue scanning the road, checking your mirrors, and looking at the instrument panel at regular intervals. Developing these safe habits will keep you attentive as a driver.

Because it is dark, drivers cannot see as well at night as they can during the day. From one half hour after sunset until one half hour before sunrise, or at any other time when persons or vehicles are not visible for 500 feet, drivers must use their headlights.

Emotions can have a great effect on your driving ability. You may not be able to drive well if you are overly worried, excited, afraid, angry, or sad. Stress can lessen your concentration on the task of driving. It is better to wait to drive than to risk driving while you are emotionally unstable.

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

Before changing lanes, you should look in your rearview and side mirrors to make sure no one is trying to pass you. You should also look over your shoulder to make sure that no one is in your blind spot.

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.

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

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

Before changing lanes, you should always verify that there are no other vehicles in the lane you want to enter by checking your mirrors and looking over your shoulder in the direction you plan to move. You should signal every time you change lanes.

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

When roads are wet, cars take a longer distance to stop and may skid on quick turns. Do not use cruise control when driving under wet or icy conditions. Reduce your speed and drive with caution.

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