What should you do if you see flashing lights behind you while driving?

When you see flashing lights behind you while driving, it is important to pull over to the side of the road. This is the appropriate response because the flashing lights typically indicate that an emergency vehicle is trying to reach you or another vehicle. By safely maneuvering to the side of the road, you enable the emergency vehicle to pass, ensuring that both you and the emergency responders can stay safe on the road.

Additionally, pulling over demonstrates compliance with traffic laws and shows respect for emergency services that may need to address a critical situation. This action prevents confusion or potentially hazardous situations that could arise if drivers failed to yield.

The other options suggest actions that could lead to dangerous situations or legal repercussions, such as increasing speed or ignoring the lights, which would be inappropriate and disrespectful to the authority and urgency of emergency responders. Turning on hazard lights is also a part of the correct response but should be done while pulling over, not as a standalone action.
