If you see an emergency vehicle with flashing lights, what action should you take?

When you see an emergency vehicle with flashing lights, the appropriate action is to move to the right edge of the road and stop. This action is crucial because it allows the emergency vehicle to pass safely and quickly.

By moving to the right, you are creating a clear path for the emergency vehicle, which may be responding to a critical situation that requires immediate access to the area. Stopping also ensures that you do not interfere with the response of the emergency personnel, which could delay their crucial work and potentially endanger lives.

Moving to the left side of the road, as suggested in another option, could place you in the path of the emergency vehicle and create unnecessary hazards. Similarly, speeding up to go through an intersection or continuing at the same speed does not prioritize safety and could lead to dangerous situations for both you and the emergency responders. Thus, stopping at the right edge of the road is the safest and most responsible action you can take in this scenario.
