What should you do if there are no emergency signals but a fire engine is behind you?

When a fire engine is behind you, the appropriate response is to change lanes to the right and stop, allowing the emergency vehicle to pass safely. Emergency responders need to reach their destination quickly in order to attend to urgent situations, such as fires or accidents. By moving to the right and stopping, you are ensuring that the fire engine has a clear path to proceed without delay.

This action not only conforms to traffic laws and regulations regarding emergency vehicles but also reflects responsible driving behavior in ensuring public safety. On the other hand, speeding up or maintaining your speed could hinder the fire engine's progress and potentially create a dangerous situation. Pulling over to the left, contrary to the expectation of yielding to an emergency vehicle, may also obstruct the engine's maneuvering space, depending on the road layout. Thus, giving way by changing lanes to the right and stopping is the safest and most legally sound choice.
