Tennessee CAR DMV Practice Test 13

To avoid the dangers of fatigued driving, take breaks every hour or so during a long trip. If possible, share driving responsibilities with another person so you can each sleep while the other person drives.

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.

Orange is the standard color for work zone activity. If you see orange signs, cones, or barrels while driving, stay alert and be prepared for unexpected driving conditions. This sign alerts drivers to an upcoming flagger whose directions should be obeyed by all drivers.

Anytime you want to merge with other drivers, you need to find a gap large enough for you to safely enter into the flow of traffic. You should not stop on the entrance ramp to an interstate highway unless there are no gaps into which you may safely merge.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited. You should match the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

All temporary signs in work zones have an orange background with black letters or symbols. These signs are found on the right side of the road, or on both the left and right sides if the roadway is a divided highway.

Diamond-shaped signs are used to warn of actual or possible hazards. The color orange is used for warning signs usually found in construction or maintenance areas.

You may proceed in the direction that a green arrow signal is pointing if you are in the proper lane, regardless of any other signals that are displayed. Before turning, you must yield the right-of-way to pedestrians and vehicles already within the intersection.

Bicycles do not have turn signals so bicyclists use hand and arm signals to alert other drivers to their intentions. If a bicyclist puts their left arm straight out, they are signaling that they intend to turn left.

Using a cell phone while driving is dangerous because it occupies the user's eyes, hands, and mind. Even the most skilled drivers increase their risk of being involved in a crash by using a cell phone on the road.

Every time you want to change lanes or otherwise move your vehicle to the right or left, signal to alert other drivers to your intentions. Always check your mirrors and turn your head to check your blind spot before attempting any lateral move.

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.

Before changing lanes, check for drivers trying to pass you who may be trying to enter the same lane as you. Look over your shoulder to check your blind spot. You should never attempt to pass or otherwise change lanes in an intersection.

Drivers of trucks, buses, vans, or any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

A green arrow means "go." You must turn in the direction the arrow is pointing after you yield to any vehicles, bicycles, or pedestrians who are still in the intersection.

When driving in a work zone, adjust your speed for the traffic conditions and don't follow other vehicles too closely. Be attentive to workers and machines in the work zone.

Pedestrians using guide dogs or white canes (with or without a red tip) must be given the right-of-way at all times.

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

Although the right-of-way rules provide a guide to determine who should yield the right-of-way at an intersection, no one should assume they automatically have the right-of-way. The situation and circumstances at an intersection must always be considered. Drivers should yield their legal right-of-way if it can help prevent a collision.

A round yellow sign indicates that there is a railroad crossing ahead.

The stop sign is the only eight-sided sign you will see on any roadway. When you encounter a stop sign, you must come to a complete stop. You may not proceed until the way is clear for you to completely and safely pass through the intersection.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign is used to warn drivers about an upcoming curve to the right.

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

Never pass within intersections or at other intersecting points, such as parking lot entrances and alleyways. Any time your view is blocked by a curve or a hill, you should stay in your lane and assume that there is an oncoming vehicle just out of sight. Wherever signs and/or pavement markings permit passing other vehicles, you will have to determine whether or not you have enough space to pass in a safe manner.

Drivers should signal when pulling next to a curb or away from a curb.

Driving defensively means anticipating potential errors made by others and preparing to compensate for their mistakes.

If your vehicle begins to skid, release the accelerator or brake pedal to regain vehicle balance. Steer in the direction of the skid to regain control of the vehicle.

You must signal your intention to turn by activating your turn signal at least 50 feet before the location of the desired turn.

This sign warns a driver of a change in direction or a narrowing of the road. A driver may find several of these signs on the outside of a sharp curve or on approaches to a narrow bridge.

Your tires do not have as much traction on loose gravel and dirt roads as they do on concrete and asphalt roads. When driving on gravel or dirt, you must slow down. It will take you much longer to stop and it is much easier to skid when turning.
