Pennsylvania CAR DMV Practice Test 22

This sign indicates that a T intersection is ahead.

This sign indicates that there is a traffic signal at the intersection ahead.

The most common type of crash in work zones is the rear-end collision. To avoid this hazard, it is recommended that you double your following distance as you approach a work zone.

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.

If you miss your turn or exit, do not back up, but go on to the next turn or exit where you can safely turn around. It is illegal to back up on a shoulder or a freeway.

You should never start a left turn until you can see that all the lanes you need to cross are clear and that you can safely make the turn.

Carelessness and speeding are the main causes of traffic-related fatalities in work zones.

This sign indicates that the road that you are on intersects with a divided highway. A divided highway is two one-way roadways separated by a median or guide rail.

Do not exceed the school zone speed limit during indicated times. The end of a reduced speed school zone will be indicated by an "End school zone" regulatory sign.

If you are stopped at a railroad crossing with more than one track, do not start moving as soon as a train passes. Wait until you have a clear view down all tracks before you start across. Even where there is only one track, do not start across immediately after a train passes; check again for another train that may be approaching.

When the flashing yellow lights on a school zone sign are activated, or during an indicated school zone time period, you may travel no faster than 15 mph.

Even at a railroad crossing with only one track, you should not immediately start across after a train has passed. Always check for other approaching trains before proceeding.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

Your horn should be used to warn other drivers or pedestrians in situations where they may not see you. For example, if you think another driver is about to hit you, you should sound your horn.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

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

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.
