Pennsylvania CAR DMV Practice Test 21

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.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

When stopped at a stop sign where you cannot see cross traffic, yield to any pedestrians and then carefully pull forward past the stop line until you can see clearly. Check for traffic and pedestrians. Go ahead when the intersection is clear.

When driving near a blind pedestrian who is carrying a white cane or walking with a guide dog, you must slow down, yield the right-of-way, and then proceed with caution. Be prepared to stop your vehicle in order to prevent injury or danger to the pedestrian.

This sign indicates that right turns are prohibited. Do not make a right turn at an intersection where this sign is posted.

You must do everything you can to prevent striking a pedestrian or another vehicle, regardless of the circumstances. It is the driver’s basic responsibility to be alert to pedestrians and to yield the right-of-way to all pedestrians, even if the pedestrian is crossing the street where they should not be.

The law requires you to allow at least four feet of space between your vehicle and a bicyclist when passing them.

A steady green light means you may drive through the intersection if the road is clear. You may also turn right or left on a steady green light unless a sign prohibits the turn. When turning, you must yield to other vehicles and pedestrians within the intersection.

Because of their size, trucks need longer distances to stop than smaller vehicles do.

As alcohol builds up in your system, it will slow your reactions, make you feel more confident, and cause you to make more errors.

A solid yellow line next to your lane means that passing is not permitted from your direction.

To ensure that you will have time to react to hazards on the roadway, it is best to keep a cushion of space on all sides of your vehicle. Do not crowd vehicles to your left and right sides.

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.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

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.

In addition to other penalties, attending an Alcohol Highway Safety School will be required for first or second offenses at any level of impairment.

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.

Pennant-shaped warning signs like this are only used to indicate a no passing zone.
