Utah CAR DMV Practice Test 3

In Utah, a driver with a minimum blood alcohol concentration (BAC) of 0.05 percent may not legally operate a vehicle. It is also against the law for a driver in Utah to drive while impaired, even with a BAC that is below the legal limit.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

If you are being followed by an emergency vehicle that is not using its siren or flashing lights, you do not need to clear a path. Continue driving in a normal manner.

When approaching an intersection with a steady green traffic light, yield to pedestrians in the crosswalk and vehicles still in the intersection. You may continue driving, but should approach the intersection at a speed that will allow you to slow down and stop if the light changes before you get there.

This sign prohibits U-turns. Do not make a U-turn where this sign is posted.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

You should allow more space in front of your vehicle than usual when you are stopped on an uphill slope. If the vehicle in front of you rolls backward toward your vehicle when traffic begins to move again, it is less likely that there will be a collision.

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.

A solid line along the side of the road indicates where its edge is, marking the boundary between the travel lane and the shoulder. If the edge line angles toward the center of the road, this means that the road is narrower ahead.

A flashing red light means that you must come to a full stop, and then proceed when the way is clear.

Children who are age 12 and younger should be safely restrained by a seat belt or in the appropriate child safety seat in the rear seat of a moving vehicle.

When turning left at a traffic signal, you must yield the right-of-way to pedestrians and oncoming traffic.

If you are involved in an accident, you must stop at or near the scene. Move your vehicle out of the way of traffic, if possible. Do not stand or walk in traffic lanes as you could be struck by another vehicle. Turn off the ignitions of wrecked vehicles.

This sign indicates that a T intersection is ahead.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

On a traffic signal arranged vertically, red is always on top and green on the bottom. When arranged horizontally, red is always on the left and green on the right.

Yield to pedestrians and cars that may be caught in an intersection when you have a green light. Be careful around pedestrians under every circumstance.

Pennant-shaped signs usually indicate no passing zones. Text will also be on the sign to confirm that it is a no passing 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.

Most warning signs are diamond-shaped and yellow with black markings. These signs warn drivers about unexpected conditions that may not be readily apparent.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

This sign indicates a low ground railroad crossing. Where this sign is present, railroad tracks cross the road at a steep slope and the bottom of low vehicles may drag or get caught on the tracks.

When passing another vehicle on a two-lane roadway, you must return to the right side of the roadway when there is enough room between you and the vehicle you have passed.
