Pennsylvania CAR DMV Practice Test 9

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

When you see an emergency vehicle using its lights or hear it using its siren, you must immediately pull over to the curb or side of the road and stop.

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

If there are no signals at an upcoming railroad crossing, you should slow down and be prepared to stop if you see or hear a train approaching.

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.

If your vehicle starts to skid on a wet or icy road, look and steer in the direction you want to go. If the rear of your vehicle is skidding to the left, turn the wheel to the left. If the rear of your vehicle is skidding to the right, turn the wheel to the right.

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

Check the traffic behind you several times a minute to know if another driver is tailgating, approaching too fast, or trying to pass. If another car is following you too closely, slow down and let it pass. Most rear-end collisions are caused by vehicles following too closely.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

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.

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.

Compared to signs and other roadside objects, pedestrians are hardest to see at night.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

Anything that causes you to take your attention away from driving, take your eyes off the road, and/or take your hands off the wheel is a distraction.

To determine a safe driving speed, you must take into account many factors, including road conditions, visibility, and the flow of other traffic. When conditions are less than perfect, safety may require you to drive more slowly than the posted speed limit.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

On narrow roads, you must allow vehicles traveling in the opposite direction at least one-half of the main-traveled portion of the road. Both vehicles must have adequate space in order for the drivers to safely pass one another.
