Minnesota CAR DMV Practice Test 21

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

Do not drive in someone else’s blind spot. Move forward or drop back so that the other driver can see you.

Before changing lanes, you should activate your turn signal in the appropriate direction and check your rearview and side mirrors. Look over your shoulder in the direction you plan to move in order to check your blind spot and check the far lane to be sure no one else is trying to enter the same lane as you. Change lanes when you are sure it is safe to do so.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

A steady yellow light indicates that a steady red light will soon appear. If you are driving toward an intersection and a yellow light appears, slow down and prepare to stop. If you are already within the intersection or cannot stop safely before entering the intersection, continue through carefully.

Because large vehicles have large blind spots on both sides, you should avoid driving beside a large vehicle for a long period of time. It is safest for you to either drop back or move forward when you find yourself directly next to a large vehicle.

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

If planning to back up your vehicle, you should check behind your vehicle before you get in. Children or small objects are difficult to see from the driver’s seat.

A "Merging lanes" sign indicates that two lanes of traffic going the same direction will soon merge into one lane. Drivers should be ready to either change lanes or allow other traffic to merge into their lane.

Lane use control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. When a lane control signal contains a flashing yellow X, drivers may only use that lane to complete a left turn.

Regulatory signs are often rectangular and white with black markings and are used to indicate what things a driver must or must not do in a designated area. They may display speed limits, prohibit passing or turning, or clarify any other driving regulation.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow and black. This sign tells drivers that a lane is ending and that they should prepare to allow traffic to merge safely.

This sign indicates that a T intersection is ahead.

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

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.

When stopped for a traffic violation or at an equipment check, the driver is responsible for producing their license, proof of registration, and proof of insurance. Drivers are required to have all three of these documents in a vehicle when it is being driven.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

A pedestrian with a disability who is utilizing a guide dog, a white cane, a wheelchair, or another assistive device, whether on a sidewalk or roadway, has the right-of-way and is granted the same rights as any other pedestrian.

Use your right turn signal after passing and before returning to your previous lane. Return to the right lane when you can see the entire vehicle you have just passed in your rearview mirror.

This sign warns of two-way traffic ahead.

When approaching an unmarked railroad crossing, slow down and be prepared to stop. Before you cross, be sure that no trains are approaching from either direction on any track. If you see or hear a train coming, stop at a safe distance from the nearest track and wait to proceed until after the train passes.

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.

This sign warns of the presence of a crossroad ahead.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that left turns are prohibited.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

In dry conditions, motorcycles can stop more quickly than cars. Therefore, a driver behind a motorcycle should allow at least three to four seconds of following distance so that the motorcyclist has time to maneuver in an emergency.

When passing, you should not return to your original lane until the entire vehicle you've just passed is visible in your rearview mirror.

When you hear the siren of an emergency vehicle, you must pull over to the curb or side of the road and stop.

A stop sign means that you must come to a full stop and yield the right-of-way to vehicles and pedestrians in or heading toward the intersection. Go again when it is safe.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. It is not affected by the type of alcoholic beverages you drink, your level of physical fitness, or how well you can "hold your liquor."

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

When merging into traffic, you should signal and enter at the same speed that traffic is moving. Always yield to other traffic when entering a roadway.

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

Smoking while driving can create dangerous distractions by causing you to take your hands off the wheel and/or your eyes off the road.

Passing on a two-lane, two-way road requires good judgment because you must use the lane belonging to oncoming traffic to complete your pass. Only pass if you may safely and legally do so.

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.

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

A yield sign means that you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.
