When must you yield to an emergency vehicle?

Answer: B — When it is using sirens and lights

You must yield to an emergency vehicle when it is using sirens and lights because this indicates that the vehicle is responding to an emergency situation. The law requires drivers to take immediate action to allow the emergency vehicle to pass safely. This often involves pulling over to the right side of the road and stopping until the emergency vehicle has passed. Yielding helps maintain the safety of emergency responders as well as others on the road, facilitating quick access to situations where they are needed. Recognizing the importance of this rule contributes to effective traffic management and enhances public safety. Other situations, such as the emergency vehicle being directly behind you or only approaching from a specific direction, do not encompass the full responsibility drivers have when emergency vehicles are in operation.
