Pennsylvania CAR DMV Practice Test 12

On slippery roads, you should increase your following distance. It may take more time to stop your vehicle than it would under normal conditions.

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.

While it is always dangerous to drive too fast on slippery roads, this is especially true when driving in turns and curves. Be sure to approach them more slowly in slippery conditions than you would under normal circumstances.

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

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.

Because large trucks must make wide turns, it may initially look like a truck is turning left when it is actually turning right. This makes it dangerous to try to pass a turning truck. Truck drivers cannot see vehicles that try to squeeze between them and the curb.

When roads become slippery, you should reduce your speed by five to ten miles per hour.

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

Penalties for a first offense of driving under the influence include a fine of between $300 and $5,000, depending on your blood alcohol concentration level.

Teenagers who get less than eight hours of sleep per night are at an increased risk of crashing their vehicles when driving.

If your vehicle begins to leave the road, continue to drive with the wheels off the pavement and reduce your speed by gently applying the brakes. When at a safe speed, turn the steering wheel to return to the pavement. Do not attempt to force your vehicle back onto the pavement by sharply turning the steering wheel.

This sign warns that there is a steep hill or downgrade ahead.

On dry pavement, four seconds of space is generally a safe following distance to allow between you and the vehicle ahead. You should always allow plenty of space when following a motorcycle.

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.

Before passing, make sure the passing lane is clear and activate the proper turn signal to show you are going to change lanes. Signal early enough for other drivers to know your plans in advance.

When you hear the siren of an emergency vehicle, you must pull over to the curb or side of the road and stop.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

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.
