Washington CAR DMV Practice Test 21

A flashing yellow arrow indicates that left turns are allowed in the direction of the arrow. However, the oncoming traffic has a green light and you must yield to oncoming traffic and pedestrians.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before driving.

Pedestrians should walk on the side of the road facing the traffic in the lane nearest them.

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 a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

You must yield the right-of-way to all emergency vehicles using a siren, air horn, and/or flashing red, blue, or white lights. Where possible, you must pull over to the right edge of the road. If you are in an intersection, drive through the intersection before you pull over.

Crashes often happen because one driver does something that other road users are not expecting. You should communicate with other motorists, bicyclists, and pedestrians by doing things like signaling when slowing down, stopping, or changing direction. Use your emergency signals or horn when appropriate.

If you drive past these signs, you are going the wrong way and are at risk of a head-on collision. You should cautiously turn around.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that there is an upcoming sharp turn and that they should lower their speed accordingly.

If your brakes stop working, pump the brake pedal several times. This will often build up enough brake pressure to allow you to stop.

At a steady red light, you may turn right provided that no posted sign prohibits it. You must come to a full stop first. Always use your turn signal before making any turn.

Worn or bald tires can increase your stopping distance and make turning more difficult. Tires without adequate tread also increase the risk of hydroplaning.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

Because of their size, trucks need longer distances to stop than smaller vehicles do.

Chevron signs like this indicate that the road curves sharply in the direction indicated by the chevron (in this case, to the left). There may be several chevron signs placed throughout a curve.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.

Work zone signs are orange and indicate that some type of work is being performed on or alongside the roadway. Be extremely careful when you see these signs.

If there is no stop line or crosswalk, you should stop at the point nearest to the intersecting roadway where you can get a view of approaching traffic. You should not enter the intersecting roadway to gain a better view.

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.

Unless otherwise posted, the speed limit in cities and towns is 25 mph.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

Even if you are using the substance legally, operating a vehicle while under the influence of marijuana is not legal. Doing so can be dangerous because the substance can distort your perception of space, time, and speed.

This sign indicates that there is merging traffic entering from the right.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.
