Tennessee CAR DMV Practice Test 12

When changing lanes, look over your shoulder in the direction you plan to move. Check for obstructions near the rear corners of your vehicle. These areas are called “blind spots” because you cannot see them by using your mirrors.

If you approach a stopped school bus that has its lights flashing and arm extended, you must come to a full stop and remain stopped until the signal arm is pulled back and the bus resumes motion. This law applies whether you are traveling in the same direction as the bus or if you are approaching from the opposite side of the street.

When making a left turn, you must yield to pedestrians, bicyclists, or other vehicles moving on their green light.

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.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

You must activate your turn signal at least 50 feet from the place where you plan to turn.

The color orange is used only for construction and maintenance warning signs.

Regulatory signs provide notice to road users of traffic laws and must be obeyed. Where this sign is posted, making a right turn is prohibited.

Treat a flashing red light the same as a stop sign. Come to a complete stop at the stop line or, if there is no stop line, prior to the crosswalk and before entering the intersection. Yield to all other traffic and pedestrians.

Increase your following distance when it is difficult to see due to darkness. Use headlights to increase visibility, following the rules for proper use of high beams and low beams. Avoid looking directly at the headlights of an oncoming vehicle to avoid being blinded by the glare.

When in a moving vehicle, a child under one year old, or weighing less than 20 pounds, must be in a child passenger restraint system that is facing the rear of the car. Children who are between one and three years old, and who weigh more than 20 pounds, must be in a child passenger restraint system that is facing forward. Children who are between four and eight years old, and under 4' 9" tall, must be in a belt positioning booster seat system and wearing a seat belt.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

This sign indicates that a divided highway begins ahead.

When passing another vehicle, move back into your original lane only when you can see the passed vehicle’s headlights in your rearview mirror. This ensures that you will have enough room to safely pull back in front of the other vehicle.

Safe use of the interstate demands drivers be constantly alert and capable of driving at high speeds.

If your vehicle becomes disabled, you must (if possible) park with all four wheels off of the main-traveled portion of the road.

At a yield sign, you must slow down or stop, if necessary, and give the right-of-way to crossing or merging vehicles. Yield the right-of-way to any cross traffic that is close enough to cause conflict.

A three-sided yield sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. In this case, you do not have the right-of-way.

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.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

Whether or not your vehicle has an airbag, your body should be 10 to 12 inches back from the steering wheel. This will reduce the risk of serious head and neck injuries in the event of a collision.

You must yield the right-of-way to any emergency vehicle that is using its siren and lights. Drive to the right edge of the road and stop until the emergency vehicle has passed. If you are within an intersection, drive through the intersection first and then stop.

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

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. There may be an upcoming change in traffic direction, a steep downgrade, or another potentially hazardous situation that requires action on the part of the driver.

A driver should watch beside, ahead, and to the rear of their car. To be a good driver, you must know what is happening all around your vehicle.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.
