Utah CAR DMV Practice Test 24

Crashes often happen when some drivers go faster or slower than other vehicles on the road. Always try to drive with the flow of traffic, within the posted speed limit.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential bicycle cross traffic.

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

You must always yield to pedestrians who are in or about to enter a crosswalk. Be alert to pedestrians when driving across intersections or turning.

Every time you have to stop quickly, it takes time and fuel to accelerate and get your vehicle back up to the speed of traffic. Drivers who look far ahead of their vehicles can slow down gradually or change lanes to avoid unnecessary braking, leading to better gas mileage.

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 an intersection of two similar roads without a traffic control device, a driver must yield to a vehicle approaching from the right.

Many crashes are caused by drivers who are driving too fast for conditions. Always drive within the legal speed limits and decrease your speed any time conditions are less than perfect.

Drivers must always yield to pedestrians in the street, even if they are crossing against a red light or are otherwise being careless.

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

When two vehicles arrive to an uncontrolled intersection at the same time, the vehicle on the right has the right-of-way. Once the vehicle on the right has safely passed through the intersection, the other driver may proceed.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

Any eight-sided sign is a stop sign. At an intersection with a stop sign, you must stop completely and check for pedestrians and cross traffic in the intersection. Wait for the intersection to clear before proceeding.

A steady downward green arrow over a traffic lane means you may use the lane indicated.

An eight-sided sign always means "stop." You must come to a complete stop and wait for any vehicles or pedestrians to clear the way before proceeding.

You should avoid making any sudden changes in speed or direction when driving on a slippery surface. Reduce your speed on slippery roads and do not use cruise control.

Drive below the posted speed limit when safety demands it. Some traffic, weather, or visibility conditions may require you to drive as slowly as 10 miles per hour.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

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

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign tells drivers that they are approaching a school zone and that they should slow down and watch for children.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

Drivers are always required to stop for a stopped school bus when driving on a two-lane road, regardless of their direction of travel. You should exercise caution when driving near children.
