Maryland CAR DMV Practice Test 19

When driving in a work zone, adjust your speed for the traffic conditions and don't follow other vehicles too closely. Be attentive to workers and machines in the work zone.

Treat a flashing red light the same as a stop sign. Come to a complete stop at the stop line or, if there is no stop line, prior to the crosswalk and before entering the intersection. Yield to all other traffic and pedestrians.

Use high beams on open roads, which are unlit by streetlights, in order to see persons or vehicles ahead. You must change to low beams at least 500 feet before meeting oncoming vehicles. You must also change to low beam lights when following a vehicle at a distance of 300 feet or less.

This sign is displayed on slow-moving vehicles.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

The only way to remove the effects of alcohol from the body is to let time pass. Eating, drinking coffee, or taking a shower will not speed up this process.

If you must stop on the shoulder of the interstate or highway, turn on your emergency flashers to warn other drivers and stay inside your vehicle, if you can. The extremely high speed of traffic makes standing or walking along an interstate highway very dangerous.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

When passing is permitted, look for both headlights of the passed vehicle in your rearview mirror. Only then may you safely return to your original lane.

When being passed, you must yield to the passing vehicle and not increase your speed. Allow the vehicle to safely merge back into your lane.

When entering a roundabout, you must yield to pedestrians, bicyclists, and traffic already in the roundabout.

A truck's blind spots are much larger than a smaller car’s blind spots. The driver cannot see your car behind their vehicle and you can't see what’s happening in traffic ahead if you're driving too closely behind the truck. Whether you are driving behind or to the side of the truck, if you can’t see the driver’s face in their side view mirror, then they can’t see you.

If there is danger, you may need to sound a sharp blast on your horn. Do this when a child or any other pedestrian is about to enter into the street in front of your moving vehicle.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

If you approach a stopped school bus that has its lights flashing and arm extended, you must come to a full stop and remain stopped until the signal arm is pulled back and the bus resumes motion. This law applies whether you are traveling in the same direction as the bus or if you are approaching from the opposite side of the street.

When encountering a flashing yellow light at an intersection, you should slow down and proceed with caution. You do not need to come to a complete stop when approaching a flashing yellow light.

Treat a flashing red traffic signal the same as you would treat a stop sign. Come to a complete stop, yield to oncoming traffic or pedestrians, and proceed when the way is clear.

Large trucks take longer to stop than other vehicles traveling at the same speed. The average passenger vehicle traveling at 55 mph can stop within 400 feet. However, a large truck traveling at the same speed can take almost 800 feet to stop.

When turning left at an intersection, yield the right-of-way to oncoming traffic and pedestrians. Once the intersection is clear and applicable signals allow, you may complete the turn.

Use your low beam headlights when following a vehicle at a distance of 300 feet or closer. High beams can reduce visibility when shining directly into a driver's face or mirrors.

A red sign informs drivers that an action is prohibited. If you see this sign, you are traveling in the wrong direction on the road and should turn around immediately.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about an upcoming winding road.

If you see an emergency vehicle approaching while using its flashing lights, pull over to the right edge of the road and stop. Position yourself parallel to the curb. On one-way streets, drive toward the road edge nearest you.

Before you drive, both you and your vehicle should be ready. You must have a valid learner's permit or driver license and vehicle registration card in your possession. You should properly adjust your seat and mirrors and ensure that all passengers are wearing a seat belt before driving.
