Michigan CAR DMV Practice Test 18

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

There are a number of locations where it is unlawful to park, including on a crosswalk or in a marked bicycle lane. When parking on the street, you must be within 12 inches of the side of the road.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. U-turns are not permitted where this sign is posted.

You should allow more space in front of your vehicle than usual when you are stopped on an uphill slope. If the vehicle in front of you rolls backward toward your vehicle when traffic begins to move again, it is less likely that there will be a collision.

After a minor collision, move your vehicle off the traveled portion of the roadway, if possible. Do not leave the scene of an accident without identifying yourself and rendering assistance.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

After an accident, do not move the injured unnecessarily. Unskilled handling can make serious injuries out of minor ones. Keep the injured warm until skilled help arrives. If there is severe bleeding, attempt to stop the flow of blood with direct pressure.

In general, vehicles at a four-way stop should proceed in the order that they arrive. However, if two vehicles arrive to the intersection at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

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.

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

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).

Diamond-shaped signs warn drivers of existing or potential driving hazards. You will usually see these signs in yellow or orange.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

This sign indicates that the road ahead turns sharply to the right and then sharply to the left.

This sign indicates that there is a traffic signal ahead.

You must always bring your vehicle to a complete stop and yield to approaching traffic before proceeding past a stop sign. Don't feel pressured by surrounding traffic to avoid making a complete stop.

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.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

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.

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

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers to be extra careful when the pavement is wet because the road may become slippery, making vehicles more difficult to control.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.

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.

If you miss your turn or exit, do not back up, but go on to the next turn or exit where you can safely turn around. It is illegal to back up on a shoulder or a freeway.

Wet roadway surfaces can be dangerously slick, especially immediately following a rainfall. When you are driving on wet roads, your vehicle is traveling on a thin layer of oil, dirt, and water. Slow down when there is heavy rain, standing water, or slush on the road to reduce the risk of your wheels losing traction on the slick surface.

When using a freeway exit ramp, do not slow down until you move onto the exit ramp.

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.

A flashing yellow arrow indicates that left turns are allowed in the direction of the arrow. However, the oncoming traffic has a green light and you must yield to oncoming traffic and pedestrians.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

Pentagonal signs indicate that you are in a school zone. Be extra alert to children and pedestrians when driving near a school.

Chevron signs like this indicate that the road curves sharply in the direction indicated by the chevron (in this case, to the left). There may be several chevron signs placed throughout a curve.

This sign indicates that U-turns are prohibited.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.
