Washington CAR DMV Practice Test 15

A shared center lane may not be used for passing or for travel of farther than 300 feet. Drivers should use these lanes to safely turn left from a multilane roadway.

You must yield to any transit vehicle that is signaling to pull back onto the main roadway after it has stopped to load or unload passengers. Change lanes, slow down, or stop to allow the bus safe re-entry into traffic.

Before backing up, you should turn to look directly through the rear window to check for hazards. Do not rely only on your mirrors. You should look left and right and yield to any vehicles, bicyclists, or pedestrians.

If your vehicle's turn signals do not work, you should use hand signals to indicate when you intend to change direction.

You must always stop before crossing railroad tracks if flashing red lights are activated, a crossing gate is lowered, a stop sign is posted, a flagger signals you to stop, or a train is visible or so close to the crossing that it would be hazardous to continue driving. If you are unsure if a train is too close for you to safely cross the tracks, stop. Never race a train.

Stopping distances increase on wet or icy roads. Stopping distances also increase on road surfaces covered in loose gravel or stones.

This sign warns that especially slippery conditions exist when the road is wet.

The purchaser of a vehicle must transfer ownership within 15 days to avoid penalty fees. If the vehicle is sold by a dealer, the transfer is the dealer’s responsibility.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

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.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

You must stop for a school bus that has its red lights flashing, whether it is the same or the opposite side of a two-lane road. You are not required to stop if the bus is on the opposite side of a road that has three or more marked traffic lanes, or that is divided by a median or physical barrier.

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.

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

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

Anytime you want to merge with other traffic, you need a gap of about four seconds. If you move into the middle of a four-second gap, both you and the vehicle behind you have a two-second following distance. You need a four-second gap whenever you change lanes, enter a roadway, or when your lane merges with another travel lane.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

This sign warns of the presence of workers on or near the roadway. Use extra caution when driving in work zones.

Any time you want to change lanes, you should properly signal your intentions well in advance, check your mirrors, and check your blind spot. You can check your blind spot by glancing over your shoulder in the direction that you plan to move.

It is illegal for a driver who is age 21 or older to operate a vehicle with a minimum THC level of five nanograms per milliliter of blood. A driver who is under the age of 21 may not operate a vehicle with any detectable amount of THC in their blood. The use of marijuana while driving can be extremely dangerous.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they are approaching an area with low clearance.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

A flashing yellow traffic light indicates that you should drive with caution.

If you are being followed by an emergency vehicle that is not using its siren or flashing lights, you do not need to clear a path. Continue driving in a normal manner.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.
