Texas CAR DMV Practice Test 20

Do not use your high beam headlights when approaching or following another vehicle at night. Switch to the low beam setting to ensure the safety of everyone on the road.

The more distance between your vehicle and others, the more time you will have to react if another driver makes a mistake. Keep a minimum following distance of four seconds when driving faster than 30 mph, under normal conditions.

Slow down and increase your following distance when the road is wet, when the road is crowded, and/or when your vision is limited. You should always be able to stop within the area you can see ahead of your car.

You should slow down and activate your right turn signal before making a right turn. Be careful not to turn too wide for your lane, as this may interfere with other vehicles.

To avoid the dangers of road rage, you should never take it personally if another driver cuts you off in traffic. Just let it go and continue driving safely.

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

Stop lines are usually painted on the roadway at a distance from an intersection to give pedestrians a walkway in front of stopped cars. Stop your car before the painted stop lines.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.

Pedestrian hybrid beacons are used at pedestrian crossings. If the signal is flashing yellow, drivers should slow down and be prepared to stop.

A flashing red light means the same thing as a stop sign. If you encounter a flashing red light, you should come to a complete stop, yield to appropriate traffic and pedestrians, and only proceed when it is safe to do so.

If an aggressive driver cuts you off on the roadway, stay calm and get out of their way. Trying to get even with an aggressive driver risks escalating the situation and increasing the danger.

When a truck passes you, help the truck driver by keeping to the far side of your lane. You’ll make it easier for the truck driver to pass safely if you slightly reduce your speed. Don’t speed up while a truck is passing your vehicle.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

A green arrow has the same meaning as a circular green traffic light, but traffic in the indicated lane must turn in the direction shown by the arrow.

"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

In the state of Texas, the driver and all passengers in a passenger vehicle are required to use safety belts if the vehicle is equipped with safety belts. This law applies to all passengers, regardless of age.

This sign warns of the presence of a crossroad ahead.

If you come to a roadway that is flooded, turn around and find another way to go. Do not attempt to drive through the water. It is impossible to determine the depth or current and your vehicle could become submerged or swept away.

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. U-turns are not permitted where this sign is posted.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

If you encounter an aggressive driver, you should make every attempt to get out of their way. You should avoid making eye contact with a hostile driver. Challenging a hostile driver by speeding up may only make them angrier, thereby increasing their danger.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

A steady yellow traffic light indicates that a red light is about to appear. Stop unless you are already within the intersection.

To avoid road rage, it is a good idea to plan ahead and allow extra time for unexpected things to go wrong on your trip. If you are trapped in traffic congestion, just relax and listen to some music you enjoy. Always drive friendly.

A flashing red light means that you must come to a full stop, and then proceed when the way is clear.
