What should you do when you see sirens or flashing lights from an emergency vehicle?

When you see sirens or flashing lights from an emergency vehicle, the appropriate action is to stop. Stopping allows the emergency vehicle the necessary space to pass safely and quickly, as they may be responding to urgent situations. By stopping, you not only comply with traffic laws but also contribute to public safety by reducing the risk of collisions.

Slowing down can sometimes be appropriate, especially if there's no immediate place to pull over, but it's crucial to ensure you are stopping when safe to do so. Keeping your speed, in this case, is considered dangerous and could obstruct the emergency vehicle's progress. Speeding up to avoid the vehicle is also irresponsible and hazardous, as it may lead to confusion and accidents as others may not know where the emergency vehicle is going. Therefore, stopping is the best and most responsible action to take.
