If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

This sign indicates that the road curves ahead in the direction of the arrow and that driving at the indicated speed of 35 mph is recommended.

Yield the right-of-way to the driver on your right at a four-way intersection if you both arrive to the intersection at the same time. You may then proceed when it is safe to do so.

Washington State has an implied consent law, which means that by operating a motor vehicle in the state, you have given your consent to take a breath test determining your blood alcohol content (BAC). You will lose your license for at least one year if you refuse to take such a test.

You must dim your high beams whenever you are within 500 feet of an oncoming vehicle.

You should avoid making any sudden changes in speed or direction when driving on a slippery surface. Reduce your speed on slippery roads and do not use cruise control.

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

If a vehicle approaching you is using its high beams and fails to dim them, you should glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see well enough to stay on your course until the vehicle passes.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

When the driver behind you wants to pass, you should slow down so that there is enough room in front of your vehicle for the other driver to complete their pass. This will allow them to complete the passing maneuver in less time and more easily.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

When you see an emergency vehicle using its lights or hear it using its siren, you must immediately pull over to the curb or side of the road and stop.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

This sign means that it is not safe for drivers to enter the indicated road or driveway from their current direction. If you come across one of these signs, you should immediately turn around and drive a different way.

To avoid the dangers of road rage, you should never take it personally if another driver cuts you off in traffic. Just let it go and continue driving safely.

When changing lanes, you should check your vehicle's blind spots by looking over your shoulder in the direction that you want to move. Always check your mirrors and turn on your directional signal before beginning a lane change.

It is against the law in Washington State to use a hand-held cell phone while driving. This law is not intended to encourage hands-free cell phone use. If a driver must talk on the phone, it is recommended that they leave the roadway and make the phone call after their vehicle is safely stopped.

It takes about one hour for the body to get rid of the alcohol in a single drink.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

Drivers entering a road from a driveway, alley, parking lot, or roadside must yield to vehicles already on the main road.
