Pennsylvania CAR DMV Practice Test 1

Passing on a two-lane, two-way road requires good judgment because you must use the lane belonging to oncoming traffic to complete your pass. Only pass if you may safely and legally do so.

You should not use cruise control on snow, in rain, in fog, or under similar hazardous conditions. Winter is the most difficult driving season and requires extra caution from drivers. It is important to consistently check your antifreeze and windshield washer fluid levels. Using snow tires can increase a vehicle's traction on the surface of slippery roads.

You may turn left after stopping at a red light if you are in the left lane of a one-way street and are turning onto another one-way street, unless a posted sign prohibits it. You must first stop and yield to pedestrians and other traffic.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

If an emergency vehicle using its lights or siren approaches while you are driving on a one-way street, you must drive toward the nearest roadside and stop.

Wet roadway surfaces can be dangerously slick, especially immediately following a rainfall. When you are driving on wet roads, your vehicle is traveling on a thin layer of oil, dirt, and water. Slow down when there is heavy rain, standing water, or slush on the road to reduce the risk of your wheels losing traction on the slick surface.

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.

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

This sign warns that a road has one-way traffic and you must not enter from your current direction.

The minimum penalties for a first underage drinking offense are a fine of up to $500, plus court costs, and a 90-day suspension.

It takes a person of average weight at least one hour to process the alcohol in a single drink.

Even if you are not driving, your driving privilege will be suspended if you are under 21 years of age and are convicted of possessing alcohol, lying about your age to obtain alcohol, or carrying a false ID card. The minimum penalties include a fine of $500, plus court costs, and a 90-day license suspension for the first offense.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

Your ability to handle dangerous traffic situations depends largely on searching for and identifying problems before meeting them. Looking far ahead of your vehicle does not mean you should simply stare at the center of the road. You need to continually scan the entire road, including the sides of the road.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

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