Texas CAR DMV Practice Test 4

Before passing another vehicle, check your mirrors and blind spots. Before changing lanes, activate the appropriate turn signal. Re-enter the lane when you can see the front of the passed vehicle in your rearview mirror.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

When driving in an urban district, the speed limit is 30 miles per hour. If a different speed limit is posted, follow the posted speed limit.

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

Lap belts should fit snugly across your hip bones and the lower part of your abdomen. Shoulder belts should sit comfortably so that you can insert your fist between the belt and your chest.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

Use caution when leaving any parking space and check all of your mirrors to make sure nothing is obstructing your vehicle’s path, especially children or other pedestrians. Be sure to use your signal to notify other drivers that you are leaving your current parking spot.

If you are turning onto a one-way street, enter into the lane that interferes the least with other traffic. Do not make a dangerous turn into traffic.

As you approach a left turn, signal your intentions three to five seconds in advance. Continually check your rearview mirror as you gradually slow down. On a multilane road, move into the left lane before reaching the intersection where you plan to turn. Yield to traffic and pedestrians and turn when your path is clear.

Backing requires extra caution because it is difficult for drivers to see behind their vehicles. Before entering a vehicle to back up, walk to the back of the vehicle to check for children and small objects.

This sign indicates that U-turns are prohibited.

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.

When approaching an intersection with a solid yellow traffic light, slow to a stop before entering the intersection, if it is safe to do so. If you can't stop safely, drive carefully through the intersection.

Pedestrians should not enter a street or crosswalk when vehicles are approaching. Though pedestrians have the right-of-way in crosswalks, a vehicle approaching from a close distance may not have the time to stop before entering the crosswalk.

If your vehicle goes into a skid, you should turn the steering wheel in the direction you want the vehicle to go. As soon as the vehicle begins to straighten out, turn the steering wheel back the other way.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

If you are entering traffic from a driveway or private road, you should yield to drivers already on the public road. Merge safely into traffic when you are able to do so.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

Pedestrian hybrid beacons are used at pedestrian crossings. If the lights on the signal turn black, drivers should proceed past the crosswalk with caution.

Use the entrance ramp to accelerate to the speed of freeway traffic and yield to traffic already using the freeway. Before entering traffic, use your mirrors and check your blind spots to verify that you have room to safely merge.

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

Crashes often happen when some drivers go faster or slower than other vehicles on the road. Always try to drive with the flow of traffic, within the posted speed limit.

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.

Slow down when driving at night and be sure you can stop within the distance illuminated by your headlights. You must use your headlights 30 minutes after sunset until 30 minutes before sunrise.

The only place where you may lawfully throw your trash on the highway is into a litter barrel. Litter barrels are also found at all rest/picnic areas. Signs may indicate when a litter barrel is ahead on the road.

Large flashing or sequential arrow panels are used in construction areas where a lane is closed. Prepare to slow down and merge in the direction indicated by the arrow.
