Texas CAR DMV Practice Test 23

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.

You must always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

This sign warns that there is a steep hill ahead.

Stop a safe distance behind motorcyclists at intersections, signals, or crossings. A full vehicle length is recommended to help prevent impact with the motorcycle should your vehicle be hit from the rear. In dry conditions, motorcycles can stop more quickly than cars, so being aware and alert at all times can help prevent a collision.

When you park on a downward-facing slope, turn your wheels sharply toward the side of the road. This way, if your vehicle starts to roll downhill, it will roll away from traffic.

It is prohibited to park on the shoulder of a freeway, except in an emergency.

Passing on a two-lane, two-way road requires good judgment because you must use the lane belonging to oncoming traffic to complete your pass. Only pass if you may safely and legally do so.

This sign warns of two-way traffic ahead.

Never stop on railroad tracks. If your car stalls on the tracks and you cannot restart it, get out and try to push the car off the tracks. If you cannot push the car off the tracks, get help. Do not begin to cross railroad tracks unless your car can entirely clear the tracks.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

It is illegal to drive so slowly that you disrupt the normal flow of traffic. You may receive a citation for driving too slowly.

When you wish to change lanes or make a turn, signal with arm signals or mechanical turn signals to inform other motorists of your intention. Signals should be activated at least 100 feet before you make a turn. If you are using mechanical signals, continue signaling until you have completed the turn or lane change.

Lane control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. When a lane control signal contains a green arrow, drivers may drive normally in the indicated lane.

After a minor collision, move your vehicle off the traveled portion of the roadway, if possible. Do not leave the scene of an accident without identifying yourself and rendering assistance.

When approaching an intersection with a steady green traffic light, yield to pedestrians in the crosswalk and vehicles still in the intersection. You may continue driving, but should approach the intersection at a speed that will allow you to slow down and stop if the light changes before you get there.

Carbon monoxide fumes are odorless and deadly. Symptoms of carbon monoxide poisoning are sudden weariness, yawning, dizziness, and nausea. The only cure is an adequate supply of fresh air.

Slow down when driving near a bicyclist with a flag on the back of their bicycle because the flag may indicate that the bicycle operator is hearing impaired. Use caution when driving near bicycles.

You should always reduce your speed and use extra caution when children are in the vicinity. They may fail to understand the danger and may run out in front of you without looking.

Always stop before entering the roadway from a driveway and yield to any approaching vehicles or crossing pedestrians. The stop should be made before crossing the sidewalk area. Failure to stop is unlawful.

Pedestrian hybrid beacons are used at pedestrian crossings. If the signal turns a steady red, drivers should come to a complete stop.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

Defensive driving is using safe driving strategies to prevent crashes. Defensive drivers should constantly be aware of their surroundings, be alert to trouble, and have plans of action prepared in case problems arise.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

If you become stranded in a snowstorm, the best thing to do is stay in your car and wait for help. You are most likely to be found if you don't leave your vehicle. Additionally, it may be unsafe to walk around outside in a snowstorm.

Any time you want to change lanes, you should properly signal your intentions well in advance, check your mirrors, and check your blind spot. You can check your blind spot by glancing over your shoulder in the direction that you plan to move.

When making a left turn where there is approaching traffic, you must wait for the approaching traffic to go through before you turn. You may enter the intersection to prepare for your left turn if the light is green and no other vehicle ahead of you plans to make a left turn.

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.
