When is it legal to turn right on red in Washington?

In Washington, it is legal to turn right on red after coming to a complete stop and ensuring that it is safe to do so. This means that drivers must first stop at the red light, just as they would at a stop sign, and then proceed only when it is clear of oncoming traffic and pedestrians. This rule is designed to enhance safety by ensuring that drivers are fully aware of their surroundings before making the turn.

The requirement of a complete stop allows for better assessment of road conditions and potential hazards, which is crucial in preventing accidents. Drivers must yield to any traffic or pedestrians present before proceeding with the turn, reinforcing the importance of vigilance while navigating intersections.

The other options do not capture the necessary conditions for making a right turn on red, such as the lack of requirement for a complete stop or the necessity of yielding to other road users.
