Pennsylvania CAR DMV Practice Test 23

This sign indicates that the road ahead curves to the right.

You should allow more space in front of your vehicle than usual when you are stopped on an uphill slope. If the vehicle in front of you rolls backward toward your vehicle when traffic begins to move again, it is less likely that there will be a collision.

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.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

If you are going to brake where other drivers may not expect it, quickly tap your brake pedal three or four times.

Solid white lines are used to mark the right edge of a road.

If the police arrest you for driving while under the influence of alcohol or drugs and you refuse to take one or more chemical tests of breath, blood, or urine, your driving privilege will be automatically suspended for one year. This suspension will remain in place even if you are found not guilty of driving under the influence.

On a traffic signal arranged vertically, red is always on top and green on the bottom. When arranged horizontally, red is always on the left and green on the right.

In the absence of signs, signals, or police instructions, drivers turning left at an intersection must yield to vehicles going straight.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

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.

Your tires become less effective at clearing water from the road as you increase your speed. If you drive too fast, they may lose their grip entirely, leaving the vehicle sliding on a film of water. This is known as "hydroplaning."

Drivers entering a roundabout or traffic circle must yield the right-of-way to drivers already in the circle.

Using a cell phone (including a hands-free phone) or any kind of audio device (including a radio or CD player) can be a dangerous distraction and contributes to the risk of a crash.

White lines separate traffic lanes traveling in the same direction. You may cross broken white lines to pass, as long as the passing lane is clear.

"No zones" are the large blind spots around trucks and other large vehicles. Drivers of smaller vehicles should avoid lingering in "No zones."

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

When two vehicles arrive to an uncontrolled intersection at the same time, the vehicle on the right has the right-of-way. Once the vehicle on the right has safely passed through the intersection, the other driver may proceed.
