Tennessee CAR DMV Practice Test 23

Large vehicles require longer distances to stop and accelerate than smaller vehicles do. Making a sudden stop in front of a large vehicle is dangerous because the other driver may not be able to stop in time to avoid a collision.

Blue signs on the roadway are service signs. They are used to provide information about motorist services, such as upcoming rest areas, food options, or nearby hospitals.

A white rectangular sign indicates that you must obey the stated rule. This sign means that drivers should not pass other vehicles for any reason.

Not getting enough sleep is a cause of poor driving behavior. Just like drugs and alcohol, sleepiness slows reaction time, decreases awareness, and impairs judgment.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

Even if you are facing a green traffic light, do not start across the intersection if there are other vehicles blocking your way. If you are caught in the intersection when the light changes to red, your vehicle will block cross traffic. You can get a ticket for blocking an intersection.

This sign indicates that there is a yield sign ahead. You should begin to slow down when you see this warning sign.

When turning, you should look to the rear and both sides of your vehicle to ensure it is safe to proceed before making the turn. Adjust your speed to safely complete the turn.

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.

When encountering a flashing yellow light at an intersection, you should slow down and proceed with caution. You do not need to come to a complete stop when approaching a flashing yellow light.

The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

After coming to a complete stop, you may turn left at a red light only if you are traveling on a one-way street and turning onto another one-way street. Only make the turn if there are no posted signs prohibiting such a turn.

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

If an oncoming driver fails to dim their high beams, you should avoid looking directly at the headlights. Instead, look toward the right edge of your lane and watch the oncoming vehicle out of the corner of your eye.

Regardless of who is to blame, the operator and/or owner of any vehicle involved in a reportable crash in Tennessee must file a report with the Department of Safety and Homeland Security within 20 days of the incident.

When broken yellow lines separate the lanes of traffic on a two-lane roadway, any driver may pass when there is no oncoming traffic.

Drinking alcohol before driving drastically increases the chance of collision. A driver with a blood alcohol content (BAC) of 0.10 percent is seven times more likely to be involved in a crash than a sober driver. A BAC of 0.15 percent increases the risk of collision 25 times, and a BAC of 0.17 percent increases the risk of collision 50 times.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

A wet, slippery road does not allow your tires the traction they need, so it is necessary to drive more slowly on a wet road than you would on a dry road. To reduce the risk of skidding, you should avoid fast turns or stops.

Tailgating is a common behavior that can lead to aggressive driving, and so it should be avoided. Drivers may face legal consequences for driving unsafely.

To avoid the need for last-minute braking or turning, consistently watch the road far ahead of your vehicle. By looking ahead and being ready to stop or change lanes if needed, you can drive more safely, save fuel, and help keep traffic moving at a steady pace.

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.

Slow down and proceed with caution if you see animals that are standing near the roadway. They may unexpectedly bolt or change direction at the last moment. Some animals travel in packs, so there may be more animals just out of sight that are also near the road.

If your vehicle begins to skid, stay off the brakes. Continue to correct your steering until the vehicle is back under your control and moving safely down the road.

The two-second rule holds true when driving at any speed on state and US highways with moderate speed limits. However, during inclement weather, interstate highway driving, and night driving, your following distance should be increased to a minimum of four seconds to supplement the increased stopping distances.

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

A DUI conviction, when the violator has not previously been convicted of a DUI, is punishable by a 48-hour jail sentence (or seven days in jail for driving with a BAC of 0.20 percent or more), a fine of between $350 and $1,500, and a one-year license revocation.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).

If your vehicle leaves the roadway, hold the steering wheel firmly, release the gas pedal, and gently apply the brakes. Wait until your speed has reduced, check the traffic, and look for a place to safely return to the roadway by merging back into traffic. Overcompensating by jerking the wheel to return to the roadway can cause you to lose control of your vehicle or may cause your car to go into other lanes of traffic.

If you are the first person to arrive at the scene of a crash, you should immediately call 911. Otherwise, if you are not professionally trained to render aid, cautiously continue on. This will ensure that you do not interfere with the arrival of emergency services and will prevent you from being the victim of a secondary collision caused by other drivers distracted by the crash scene.
