Texas CAR DMV Practice Test 21

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

Driving While Intoxicated is a problem affecting all Texans. Alcohol-related crashes represent 29 percent of the total number of persons killed in motor vehicle traffic crashes.

This sign indicates that there is a traffic signal ahead.

When entering a roundabout, you must yield to pedestrians, bicyclists, and vehicles that are already in the roundabout.

A roundabout is a circular intersection that flows in a counterclockwise direction around a central island and usually does not include a traffic signal. Motorists must enter from the right, yielding to traffic already in the roundabout, and follow the circle to the right until the desired roadway is reached.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Texas drivers are required to have license plates attached to both the front and rear of the vehicle. Any motor vehicle owned by a Texas resident cannot be parked or driven on a public street or highway unless it is properly registered and displays license plates.

You should slow down and activate your left turn signal before making a left turn. Be careful not to cut the corner short, as this may interfere with other vehicles.

Special child seats are available for children who are too small to wear regular safety belts. No person is strong enough to safely hold onto a child of any size during an accident or sudden stop. Never allow a child to ride in a vehicle unless they are properly fastened into a seat.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

The distance that a vehicle needs to stop depends on the motorist's reaction time, weather and visibility conditions, the vehicle's weight, the conditions of the vehicle's brakes, the condition and type of the vehicle's tires, roadway conditions, and speed.

This sign indicates that there is merging traffic entering from the right.

If a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

Safety belts can double your chance of surviving a crash and more than double your chance of avoiding serious injury. Airbags, when used properly with safety belts, provide additional protection in a front-end crash. You should wear both shoulder and lap belts.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

This sign indicates that an intersection with a crossing road is ahead.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

You should not park within 30 feet of a traffic control signal, such as a stop sign, a flashing signal, or a yield sign. An improperly parked vehicle may cause a crash.

When two vehicles arrive to an uncontrolled intersection at the same time, the vehicle on the right has the right-of-way. Once the vehicle on the right has safely passed through the intersection, the other driver may proceed.

A reflective orange triangle on the rear of a vehicle means the vehicle is traveling at speeds slower than 25 mph. You may see this decal on construction equipment, farm vehicles, and horse-drawn wagons or carriages.

A flashing yellow traffic light indicates that you should drive with caution.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane.

Operating a motor vehicle is a privilege. If this privilege is abused, it may result in a driver license suspension or revocation.

A flashing yellow arrow indicates that left turns are allowed in the direction of the arrow. However, the oncoming traffic has a green light and you must yield to oncoming traffic and pedestrians.

A motorcycle is a full-size vehicle with the same privileges as any other vehicle on the roadway. You should allow a motorcyclist a full lane width. Although it may seem as though there is enough room in the traffic lane for a larger vehicle and a motorcycle, remember that the motorcycle needs room to maneuver safely.

If you pass on the right, do so only when conditions permit you to do so legally and safely. You should never pass another vehicle on the right by leaving the main paved road.

Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

Pedestrian hybrid beacons are used at pedestrian crossings. If the signal is flashing red, drivers should come to a complete stop before proceeding.
