Tennessee CAR DMV Practice Test 15

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

When driving on an interstate highway, be aware of upcoming on-ramps. When traffic permits, move out of the right-hand lane to allow vehicles to enter from the on-ramps to your right.

This sign means drivers cannot make a left turn. It is unsafe and unlawful to make a left turn at an intersection where this sign is posted.

When approaching a yield sign, drivers must give the right-of-way to traffic already in the lanes that they intend to enter or cross. Drivers should be prepared to stop when approaching a yield sign but may continue without stopping if there is no conflicting traffic.

A three-sided yield sign indicates that you are approaching an intersection where you must wait for vehicles on the other roadway to pass before you proceed. You do not need to come to a complete stop if you are sure that no other vehicles are coming, but you should still always slow down and enter the intersection with caution.

An advisory letter will be sent to adult drivers who accumulate between six and 11 points on their driving record within 12 months. The same letter will be sent to juvenile drivers who accumulate between one and five points within 12 months.

Drivers should be alert to the presence of crossing guards when near a school and must always obey their instructions.

When traffic permits, you should make room to allow vehicles to merge into your lane.

Before changing lanes, signal, look in all your mirrors, and look over your left or right shoulder to make sure the lane next to you is clear. Looking over your shoulder is a way to check your blind spot to be sure there is no vehicle, motorcycle, or bicycle traffic in the next lane.

When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

Pavement is particularly treacherous when it first begins to rain. Accumulations of dirt and oil mix with the rainwater, creating a greasy film on the roadway.

Excessive vehicle speed can have disastrous effects. As a vehicle's speed increases, the potential impact of a collision also increases, elevating the possibility of serious injury and death. Increase your following distance as your speed increases to ensure that you will be able to stop safely if needed.

If you see an emergency vehicle approaching while using its flashing lights, pull over to the right edge of the road and stop. Position yourself parallel to the curb. On one-way streets, drive toward the road edge nearest you.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

Use high beam headlights only when driving in rural areas and when other cars are not nearby. Lower your headlights to their low beam setting when you are following closely behind another driver.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

A broken yellow line alongside a solid yellow line means that traffic in the lane next to the broken line may cross the line to pass, while traffic in the lane next to the solid line may not.

Drivers traveling at speeds above the safe and legal speed limit is a major contributing factor to fatal traffic accidents in Tennessee.

To avoid being blinded when driving at night, do not look directly at the headlights of oncoming cars. Instead, look toward the right edge of the road until the oncoming driver has passed.

A flashing red traffic light means the same thing as a stop sign. When arriving at an intersection with a flashing red light, you must come to a full stop and proceed when it is safe to do so.

Alcohol reduces all of the important abilities you need to drive safely. Alcohol goes from your stomach to your blood, then from your blood to all other parts of your body. Alcohol affects the areas of your brain that control judgment and skill.

Driving during the first half hour of rainfall is dangerous because roadways become extremely slippery when the water mixes with oil and other chemicals on the road surfaces that have not yet washed away. Use extra caution when driving on slippery roads.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.

If stopping at a curb to park, you must be within 18 inches of the curb. Only park where it is safe and legal to do so.

Dashed yellow lines separate single lanes of traffic moving in opposite directions. Passing is allowed when there is no oncoming traffic in the passing lane.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

You must turn on your headlights any time conditions prevent you from seeing other vehicles. Other drivers may have trouble seeing you, too.

Some warning signs have a fluorescent yellow-green background. These signs warn of upcoming conditions, including roads with curves and sharp turns.
