Wisconsin CAR DMV Practice Test 18

Double solid yellow lines are used to mark roadways where passing is prohibited from both directions. You may cross these lines only to make a left turn into or from an alley, private road, or driveway.

When making a left turn, you must yield to pedestrians, bicyclists, or other vehicles moving on their green light.

You should always slow down before entering a curve. You may not be able to see hazards ahead and braking in a curve may cause your vehicle to skid.

When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

When turning left from a one-way street onto another one-way street, you should begin the turn from the far left lane.

If your wheels drop off the pavement and onto a low shoulder, you should reduce your speed without braking and very carefully turn back onto the pavement. Be aware of any nearby traffic when re-entering the road.

Alcohol and other drugs can negatively effect a number of skills needed for safe driving, including a driver's reaction time, coordination, alertness, and ability to concentrate.

When traffic permits, you should make room to allow vehicles to merge into your lane.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

When a school bus is flashing its red lights and has its stop arm extended, motorists must come to a full stop until the lights are turned off, the stop arm is withdrawn, and the bus begins moving again.

This sign is used with a traffic signal to tell drivers that left-turning traffic does not have the right-of-way and must instead wait for oncoming traffic to clear.

Before changing lanes, it is very important to check behind you. You should look over your shoulder to ensure that you are not getting in the way of vehicles in the lane you want to enter. Before changing lanes, you should also ensure that no drivers are attempting to drive into the same spot from a different lane.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

Warning signs are usually yellow with black markings. This sign indicates that you are approaching a steep hill. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

If you hear the siren or see the flashing lights of an emergency vehicle, you must slow down, provide a clear path for the vehicle, and stop. Don't try to outdrive the emergency vehicle.

If you are stopped by the police, keep your hands on the wheel and ask any passengers to keep their hands in view as well. You should remain in the vehicle unless the police officer asks you to get out. Wait until the officer asks you to retrieve your driver license, registration, and insurance cards.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.

Highway work zones are established according to the type of work underway along the roadway. Signs in work areas are typically diamond-shaped, orange, have black letters or symbols, and serve as a warning that people are working on or near the highway.

This sign warns that there is a flag person ahead. Always follow directions given by a flagger. Flaggers normally wear orange or yellow vests, yellow-green shirts, or bright jackets. They use paddles and red flags to direct traffic through the work zone and to let workers or construction vehicles cross the road.

Regulatory signs display laws that drivers must always obey. Right turns are not permitted where this sign is present.

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

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign alerts drivers to the right lane ending and tells them to prepare for potential merging traffic.

Other cars and motorcycles are often hidden in a vehicle’s blind spot, so be sure to glance over your shoulder before you begin a lane change. Begin signaling 100 feet before changing lanes or turning in a residential area. Signal five seconds in advance when changing lanes on a freeway.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

If your vehicle’s accelerator sticks open, your vehicle will continue to maintain its speed or accelerate, even if you remove your foot from the gas pedal. Turn off the ignition, using care to move the ignition switch only far enough to stop the engine and not engage the steering wheel locking mechanism. Apply your brakes and move off the road to a safe area.

When leaving an alley, driveway, or parking lot to enter a roadway, you must stop before driving onto a sidewalk or sidewalk area. Pedestrians and existing traffic have the right-of-way.

After coming to a full stop, vehicles should proceed through a four-way stop in the order in which they arrive to the intersection. If multiple vehicles arrive at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

When passing another vehicle on its left, you may move back into the right lane when the headlights of the passed vehicle can be seen in your rearview mirror. Always signal before changing lanes.

You cannot pass safely when driving on a two-way, two-lane street unless you can clearly see the road ahead, you can return to your lane before meeting oncoming traffic, and your vehicle is capable of the speed necessary to pass. Do not pass where it is illegal and unsafe to do so.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).
