District Of Columbia CAR DMV Practice Test 7

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

When being approached by an emergency vehicle that is using its lights and/or sirens, you must immediately pull to the right side of the road and allow it to pass.

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.

At a four-way stop, you must yield the right-of-way to drivers who arrived before you. Wait your turn to enter the intersection.

Diamond-shaped signs are used to warn drivers about upcoming hazards or special conditions. Construction areas are usually indicated by orange-colored warning signs.

Yellow centerlines are used to separate traffic moving in opposite directions. Broken lines may be crossed to pass slower-moving traffic when it is safe to do so.

If your vehicle begins to skid, stay off the brakes. Continue to correct your steering until the vehicle is back under your control and moving safely down the road.

Only the passage of time will allow a person to overcome the influence of alcohol.

The only way to remove the impairing effects of alcohol is to give the body time to remove it from the body. Drinking coffee, physical activity, or taking a cold shower will not speed up this process. It takes about one hour to cancel the effects of one drink.

When parking downhill, turn your front wheels toward the curb or edge of the road. When parking uphill on a road without a curb, turn your wheels toward the edge of the road. When parking uphill on a road with a curb, you must turn your front wheels away from the curb.

When turning left from a one-way street onto another one-way street, you should begin the turn from the far left lane.

When driving on an interstate highway, be aware of upcoming on-ramps. When traffic permits, move out of the right-hand lane to allow vehicles to enter from the on-ramps to your right.

A railroad crossing crossbuck sign is considered a yield sign and a driver must yield the right-of-way to any oncoming trains and railroad equipment.

This sign indicates that you are approaching a railroad crossing.

A broken yellow centerline next to your side of the road indicates that traffic may cross the centerline to pass from your side of the road.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

The only way to avoid the risks of drinking and driving is to decide before you start drinking that you are not going to drive. Because alcohol affects your judgement, it will be harder for you to make safe decisions after you have started drinking.

This sign is used with a traffic signal to tell drivers that left-turning traffic does not have the right-of-way and must instead wait for oncoming traffic to clear.

Your driver license can be revoked in the District of Columbia if you are convicted of a drug offense, even if it is not driving-related.

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

When on a roadway with two or more lanes, you should make room for entering vehicles. If there is no one driving next to you, move over one lane.

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.

You must use your headlights at any time when conditions prevent you from seeing other vehicles and when it may be difficult for other drivers to see you. Always use your low beam headlights if weather conditions require you to use your windshield wipers.

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

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.
