Tennessee CAR DMV Practice Test 18

By definition, blind spots are areas that cannot be seen using your mirrors. To check your blind spots, you should look over your shoulders.

Do not go around or under any lowered gate at a railroad crossing. Once the gate is raised, do not proceed across the tracks until you can see clearly in both directions and are sure there are no trains coming.

The only way to remove the impairing effects of alcohol is to give the body time to remove it from the body. Drinking coffee, physical activity, or taking a cold shower will not speed up this process. It takes about one hour to cancel the effects of one drink.

Only the passage of time can remove alcohol and its impairing effects from the body.

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.

Before you enter an intersection, look to both the left and right for approaching vehicles or crossing pedestrians. Look to your left a second time, as vehicle approaching from your left will be closer than those approaching from your right. Look across the intersection before you start to move to make sure the path is clear all the way through.

Even if your light is green, you must not enter an intersection unless you can get completely through the intersection before the light turns red. If you block the intersection, you can be cited.

As daylight begins to fade, turn on your low beams to help others see you. Only use your high beam headlights in an open area where no other drivers are present.

Holding a driver license is not a right. It is a privilege that must be earned and maintained.

At a green light, you must give the right-of-way to any vehicle, bicyclist, or pedestrian in the intersection. If a pedestrian begins crossing the street after the traffic signal light starts flashing, wait until they have crossed the street before proceeding.

Signs with a red circle and diagonal line over a black symbol indicate that the action represented by the symbol is prohibited. In this case, the sign indicates that left turns are prohibited.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

It is illegal to cross the centerline to pass when driving on hills, in curves, and in other locations where you cannot see ahead far enough to pass safely. You may not pass at street crossings, at railroad crossings, where signs indicate no passing zones, or where a solid yellow line is next to your lane. You may not pass when the vehicle in front of you has stopped for a pedestrian or when driving in work zones where passing would be hazardous.

Bicycles are considered vehicles when used on roadways. Bicyclists and motorists are expected to follow the same rules of the road.

Drivers must always yield the right-of-way to pedestrians in the roadway, even if there is not a marked crosswalk.

Slow down before you enter a curve because you do not know what may be ahead. Braking on a curve may cause you to skid.

The only way to remove the effects of alcohol from the body is to let time pass. Eating, drinking coffee, or taking a shower will not speed up this process.

Avoid "rubbernecking," or slowing down to look at collisions or anything else out-of-the-ordinary. This helps to relieve traffic congestion.

If you experience a tire blowout, you should slow down gradually by taking your foot off of the accelerator. Don't apply the brakes until the vehicle has slowed considerably.

Low beam headlights should be used when driving in rainy or foggy weather. Even if they do little to help you see, low beams will make it easier for others to see you.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

On cold, wet days, shaded spots on a roadway can become icy. Shaded areas often freeze before, and thaw out after, the rest of a road.

Orange warning signs are used in and around work zones. Use special caution when you see orange signs, cones, or barriers on a roadway.

If you are driving under the influence and are involved in a crash that results in death, you will be charged with vehicular homicide. A conviction for vehicular homicide may result in a fine and prison sentence.

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

Warning signs are usually yellow with black markings. This sign warns drivers about an upcoming steep hill. Drivers should slow down and be ready to control their speed and protect their brakes from damage.

Warning signs are usually yellow with black markings. This sign warns drivers that the upcoming road will curve right, followed by a curve to the left. Drivers should adjust their speed to safely continue on the road.

You need a longer distance to stop your vehicle on a slippery road than you do on a dry road. Maintain an increased following distance when driving on slippery roads.

It is important to remember that driving is a privilege and that all drivers play a role in ensuring that everyone remains safe on the roadways. If you prove to be abusive of that privilege, the privilege may be revoked.
