Wisconsin CAR DMV Practice Test 20

If you miss your exit, you should take the next exit. Do not stop or back up on the highway, swerve across multiple lanes to try to make the exit at the last second, or cross over the median to turn around. All of these maneuvers are illegal and extremely dangerous.

To avoid the dangers of fatigued driving, take breaks every hour or so during a long trip. If possible, share driving responsibilities with another person so you can each sleep while the other person drives.

If your vehicle begins to leave the road, continue to drive with the wheels off the pavement and reduce your speed by gently applying the brakes. When at a safe speed, turn the steering wheel to return to the pavement. Do not attempt to force your vehicle back onto the pavement by sharply turning the steering wheel.

To check your blind spot, glance over your shoulder in the direction that you want to move.

If your power steering stops working, additional effort will be required to maintain steering control. Reduce your speed and pull off the roadway to stop in a safe area.

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

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.

It is illegal to drive so slowly that you disrupt the normal flow of traffic. You may receive a citation for driving too slowly.

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

Drivers must respect and cooperate with all other road users and conform to specific rules in order to maintain order and to avoid crashes. When encountering an aggressive driver, it is safest to just get out of their way. Always avoid competing with other drivers.

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

Worn or bald tires can increase your stopping distance and make turning more difficult. Tires without adequate tread also increase the risk of hydroplaning.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

Traffic signs with three sides of equal length warn drivers to slow down when approaching an intersection and to be prepared to come to a complete stop to yield to other drivers or pedestrians. Drivers may proceed when it is safe to do so.

When driving near a blind pedestrian, using your horn may be dangerous. Yield to the pedestrian and proceed when it is safe to do so.

Many kinds of drugs can impair your ability to drive. This includes illegal drugs and legal prescription or over-the-counter medications. It can be a criminal offense to drive while impaired by any drug.

Orange, diamond-shaped signs are used to mark construction, maintenance, survey, and utility work areas. These signs help direct drivers and pedestrians safely through dangerous zones. Fines for traffic convictions may double in areas marked by these signs.

This sign indicates that there is a traffic signal at the intersection ahead.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

When parking on an incline where there is a curb, you should turn your wheels sharply to the left, away from the curb. This way, if your brakes fail, your vehicle will not roll into traffic.

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.

Use your low beam headlights when driving in fog, rain, or snow. High beam lights can reflect off the weather conditions, lowering visibility even more.

Drivers turning left must yield to oncoming vehicles that are driving straight ahead. A turning driver may only proceed when they can safely turn without affecting oncoming traffic.

Your horn should be used as a warning in situations where you think another driver or a pedestrian does not see you. For example, if a child begins to run into the street in front of your vehicle, you should sound your horn.

Guide signs, sometimes known as destination signs, have a green background and provide directional and mileage information to specific destinations. They can be a helpful resource when driving in unfamiliar locations.

White lines between lanes indicate that the lanes are traveling in the same direction. Broken white line markings indicate that it is legal to pass another vehicle when safe.

Being under the influence of alcohol affects your judgment. Good judgement is necessary to react appropriately to things that you see or hear while on the road. Even if you are below the legal blood alcohol limit, consuming any amount of alcohol is likely to affect your ability to drive safely.

You should avoid passing other vehicles on two-lane roads. Every time you pass a vehicle, your odds of being in a collision increase.

Because your tires will not grip the road under wet, snowy, or icy conditions as well as they will under dry conditions, you should slow down if the roadway is wet or icy.

This sign indicates that U-turns are prohibited. You may see a sign like this at an intersection that commonly has oncoming traffic.

To obtain a probationary license, an applicant under the age of 18 must have accumulated 30 hours of behind-the-wheel driving experience. 10 of those hours must have been completed at night.

When driving under snowy or icy conditions, you should make speed and directional changes gradually. Never use cruise control when driving on snow or ice because your tires may lose contact with the road and you will lose control of your vehicle.

Blind spots are areas that a driver cannot see if they look in their mirrors. Large trucks have large blind spots that drivers of other vehicles should avoid.

To ensure that you can see clearly while on the road, remove snow, ice, and frost from all windows before driving. Always keep your headlights, brake lights, and taillights clean.

When a steady yellow light appears on a traffic signal, you should prepare to stop. If you are already within the intersection, you should clear the intersection as quickly as possible.
