Michigan CAR DMV Practice Test 22

A reflective orange triangle on the rear of a vehicle means the vehicle is traveling at speeds slower than 25 mph. You may see this decal on construction equipment, on farm vehicles, and horse-drawn wagons or carriages.

This sign warns of the presence of a hill ahead.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

A sign with a red circle and slash over a symbol indicates that the action represented by the symbol (in this example, a right turn) is not allowed.

This sign warns of an upcoming winding road with three or more curves.

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

The combination of alcohol and drugs, in some cases, can increase the effects of both the drugs and alcohol. It can be unsafe to drive after consuming either alcohol or drugs and is even more dangerous after combining them.

A truck or bus has blind spots on each side, in the rear, and in the front. An automobile cannot be seen in these blind spots. These blind spots are referred to as the “No zone.”

If you are turning left from a two-way street onto a one-way street, you should complete the turn into the lane closest to the lane you have just left.

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.

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.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

Pumping the brakes is generally the best way to stop a car in an emergency. The car will stop quickly and you will also be able to continue steering.

When you drive, make sure each person in your vehicle wears a seat belt. In the event of a crash, a person without a seat belt becomes a flying object and a danger to each person in the vehicle.

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.

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.

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.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. If there is a flagger at a crossing, you must obey all of their instructions.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

Fog can greatly reduce your ability to see other vehicles, pedestrians, and traffic signals. When driving in fog, drive cautiously and at reduced speeds. Do not use high beam headlights. Low beams better illuminate the road and objects ahead in foggy conditions.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

This sign indicates that there is a sharp right turn ahead.

Double solid yellow lines in the center of the road mean that passing is not allowed from either direction. You may not cross the lines unless you are making a left turn or passing pedestrians, bicyclists, and riders of scooters or skateboards when the opposite lane is clear and you can pass safely.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

Motorcycles are entitled to the width of a full lane. Be sure your vehicle is entirely in the left lane before attempting to pass a motorcycle on the left.

If a driver's left arm and hand are extended downward, they are indicating that they intend to stop. Adjust your driving accordingly if following a driver who is using this hand signal.

If a tire blows out while you are driving, hold the steering wheel tightly and keep the car headed straight down the road. Ease your foot off the gas pedal and do not apply the brakes until you have complete control. When the car is under control, brake gently and pull off the road at the nearest safe location.

A "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

When you see an emergency vehicle using its lights or hear it using its siren, you must immediately pull over to the curb or side of the road and stop.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

It is important to stay alert on highways and be ready to react to unexpected hazards. To avoid "highway hypnosis," you should avoid looking at any one thing for more than a few seconds.

As alcohol builds up in your system, it will slow your reactions, make you feel more confident, and cause you to make more errors.
