District Of Columbia CAR DMV Practice Test 4

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

This sign marks the presence of a crosswalk. Be alert to any pedestrians that may be crossing the roadway.

After an accident, do not move the injured unnecessarily. Unskilled handling can make serious injuries out of minor ones. Keep the injured warm until skilled help arrives. If there is severe bleeding, attempt to stop the flow of blood with direct pressure.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

When driving on wet roads, drivers should increase their following distance.

Driving while impaired or intoxicated is a serious traffic safety problem. Safe driving is not possible when you drink alcohol or take other drugs. Driving under the influence is dangerous both to you and to others on the road.

It is important to remember that driving is a privilege and that all drivers play a role in ensuring that everyone remains safe on the roadways. If you prove to be abusive of that privilege, the privilege may be revoked.

Pentagonal signs indicate that you are in or are approaching a school zone and/or school crossing. Be aware of children when driving near a school zone and follow posted speed limits.

When you are turning left from a two-way street, begin in the lane closest to the centerline and start your turn just before the front of your car reaches the center of the intersection. Do not cut the corner. Steering hand-over-hand, turn into the first available legal lane.

You are required to use your headlights during the day when visibility is reduced to 500 feet or less. When you first turn on your headlights, be sure they are adjusted to the low beam setting. Using high beams in fog or rain will cause the light to reflect back into your eyes, lowering visibility even more.

If your vehicle’s accelerator sticks open, your vehicle will continue to maintain its speed or accelerate, even if you remove your foot from the gas pedal. Turn off the ignition, using care to move the ignition switch only far enough to stop the engine and not engage the steering wheel locking mechanism. Apply your brakes and move off the road to a safe area.

Signs providing information about destinations are green with white letters or symbols.

"No zones" are areas around trucks or buses in which cars disappear into the larger vehicle's blind spots. "No zones" can also be defined as areas in which cars are so close to the larger vehicle that they restrict the truck or bus driver’s ability to stop and maneuver safely. A car being in a "No zone" greatly increases the potential for a crash.

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.

Stop before the stop line or crosswalk at any intersection that is controlled by a stop sign. If there is a stop sign but no stop line or crosswalk, stop before entering the intersection and proceed when it is safe to do so.

Flashing red lights, lowered crossing gates, and/or bells at a railroad crossing mean that you must come to a complete stop. You must not go across the tracks until the lights and bells have stopped and the crossing gates are completely up. Do not drive around or under a gate that is moving up or down.

An arrow painted on the pavement within a traffic lane indicates that drivers in the lane must make the movement indicated by the arrow. Drivers should follow directions given by any traffic signs or signals before proceeding in the direction indicated by the arrow.

A round sign always indicates that you are approaching a railroad crossing.

A broken yellow centerline means that a driver may cross the centerline to pass another vehicle on the left as long as there is no oncoming traffic. Drivers should never cross a solid yellow centerline in order to pass.

Stopping suddenly can make it difficult for drivers behind you to avoid a rear-end collision. When stopping, release the accelerator to allow your vehicle to slow. Press the brake pedal by applying steady pressure, activating your brake lights and causing the vehicle to stop smoothly.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

When turning, you should reduce to a speed that allows you to maintain control of your vehicle, stay in your lane, and react to unexpected situations.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

If possible, try to only deal with one roadway hazard at a time. If you want to pass a pedestrian but an oncoming vehicle is approaching, slow down and let the vehicle pass. You may then pass the pedestrian if it is safe to do so.
