Minnesota CAR DMV Practice Test 17

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

Speed limit signs indicate the maximum or minimum safe speed that is allowed to be driven on a roadway. The maximum limits are for ideal conditions and you must reduce your speed when conditions require it.

Stop lines are solid white lines painted across traffic lanes at intersections and pedestrian crosswalks. They indicate the exact location at which approaching drivers must stop.

When on a roadway with two or more lanes, you should make room for entering vehicles. If there is no one driving next to you, move over one lane.

Your turn signals should always be used when you make any movement to the left or right. You should use your signal when pulling into traffic from a curbside parking space, moving into a new lane, or passing another vehicle.

In a situation requiring you to yield the right-of-way, you must also stop if you cannot merge safely into the flow of traffic.

A U-turn is a 180-degree turn resembling the shape of the letter U and reversing the direction of travel. You may not make a U-turn unless you can do so safely and without disrupting other traffic.

Drivers may not use a cell or mobile telephone for text messaging while driving, except in the case of an emergency. Looking away from the road for any amount of time increases the possibility of a collision.

Driving faster than the posted speed limit is illegal. The posted speed limit is the maximum speed permitted on a particular road. However, the speed limit on a multilane highway with a posted speed limit of 55 mph or higher is increased by 10 mph when the driver is lawfully passing another vehicle in the same direction.

Pedestrians should not enter a street or crosswalk when vehicles are approaching. Though pedestrians have the right-of-way in crosswalks, a vehicle approaching from a close distance may not have the time to stop before entering the crosswalk.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

Pedestrians have the right-of-way when crossing the road at an intersection. A crosswalk exists anywhere that two streets intersect, whether the crosswalk is marked or unmarked.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

Regulatory signs regulate the movement of traffic. They are usually white with black markings and must always be obeyed by motorists.

You must not drive at a speed that is faster than is reasonable and prudent. You must drive at a speed that is appropriate for the area where you are driving, the type and condition of surrounding traffic, the presence of pedestrians, the weather, the quality of the road, and light conditions. You must drive within legal speed limits.

This sign is placed at the beginning of one-way streets and ramps to indicate that you must not continue driving in your current direction.

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 a green arrow is shown with a red light, you can only drive in the direction of the arrow and only if the intersection is clear.

One multilane roadways where passing is permitted, you may pass on the left side of vehicles ahead of you. You should not exceed the posted speed limit to complete a pass unless the speed limit is 55 mph or above.

Double solid lines indicate that you may not pass or change lanes. You cannot cross the lines unless it is to turn left to enter or exit a highway, to turn into or from a driveway, or to make a U-turn (where permitted).

If a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

This sign indicate that the right lane ends ahead.

A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

This sign indicates that right turns are prohibited. Do not make a right turn at an intersection where this sign is posted.

When approaching a flashing red signal, you must stop and yield to all traffic that does not have to stop.

Drivers may not park within 10 feet of a fire hydrant. Park where drivers can clearly see your vehicle from both directions.

When heavy rain reduces visibility, reduce your speed. Turn on your headlights so other drivers can see your vehicle. If the rain is so heavy that you are unable to see clearly, drive onto the shoulder and stop until the rain lets up.

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.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

You must never attempt to share a lane with a motorcyclist, even if it looks like there is enough room to do so. Motorcyclists need to have a full lane width to be able to maneuver safely.

Distractions cause drivers to react more slowly to traffic and hazards on the roadway. Distracted driving is never safe.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

When entering a roundabout, you must yield to pedestrians, bicyclists, and vehicles that are already in the roundabout.

You are responsible for driving with extreme caution where children are present. Slow down near schools and playgrounds and in residential areas.
