Michigan CAR DMV Practice Test 8

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

When approaching a roundabout, slow down. A roundabout is designed to be driven at a low speed.

An eight-sided sign always means "stop." You must come to a complete stop and wait for any vehicles or pedestrians to clear the way before proceeding.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

Work zones are often stationary, but they may also be present in the form of moving vehicles striping lines, mowing, or removing snow. Work zones are marked by orange signs with black lettering or symbols. Slow down and pay extra attention when approaching or driving through a work zone.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

This sign indicates that the road that you are on intersects with a divided highway. A divided highway is two one-way roadways separated by a median or guide rail.

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.

This signs indicate that U-turns are prohibited in the location where it is posted.

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.

This sign marks parking spaces that are reserved for people with disabled parking permits.

Unless otherwise posted, the speed limit on streets that are not designated highways, freeways, or subdivision roads is 55 mph. If a different speed limit is posted, you should follow that speed limit.

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.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers that the right lane is ending or that the road is narrowing ahead.

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

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.

You should not stop in a travel lane for any reason. Instead, keep moving until you can safely pull off of the road. If you miss your turn or exit, do not back up. Go to the next turn or exit or where you can safely turn around.

Do not exceed the school zone speed limit during indicated times. The end of a reduced speed school zone will be indicated by an "End school zone" regulatory sign.

If you miss your turn or exit, do not back up or try to turn around on the highway. Go to the next exit and safely turn around.

You must yield to other drivers when entering a street from an alley, driveway, or garage. You must also yield to pedestrians who are on an intersecting sidewalk.

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."

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.

Unless a posted sign indicates otherwise, a traffic signal displaying a red arrow means that drivers must come to a full stop and remain stopped until a green light or green arrow appears.

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.

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.

Warning signs advise drivers of potentially hazardous conditions. For your own safety, obey warning signs. Disregarding the information provided by a warning sign may result in an accident due to your negligence.

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

Drivers should always look down the road 12 seconds of their vehicle. Looking ahead may help prevent sudden stops or turns.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning devices, such as gates or flashing lights. Not all railroad crossings are equipped with such devices. It is against the law to drive around lowered railroad crossing gates.

This sign marks a high occupancy vehicle (HOV) lane. HOV lanes are reserved for use by buses and vehicles with a driver and one or more passengers, as indicated on the sign.

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.

The distance required to stop your vehicle depends on perception time, reaction distance, and braking distance. This changes with speed and road conditions.

This sign warns that especially slippery conditions exist when the road is wet.

You should not use cruise control on snow, in rain, in fog, or under similar hazardous conditions. Winter is the most difficult driving season and requires extra caution from drivers. It is important to consistently check your antifreeze and windshield washer fluid levels. Using snow tires can increase a vehicle's traction on the surface of slippery roads.
