What should you do if you see an emergency vehicle with its lights flashing?

Answer: C — Pull over to the right side and stop.

When you see an emergency vehicle with its lights flashing, the appropriate action is to pull over to the right side of the road and stop. This response is crucial for several reasons. First, it allows emergency responders to navigate the roadway safely and reach their destination without delays. Pulling over provides a clear path for them and reduces the risk of an accident involving the emergency vehicle and other drivers. Additionally, stopping ensures that you are in compliance with Washington State laws, which mandate that drivers must yield to emergency vehicles in this manner. By pulling over and stopping, you help maintain safety for everyone on the road. It is also important to stay attentive and continue observing the movement of the emergency vehicle, as it may need to change lanes and could potentially require additional room.
