What should a driver do when they see an emergency vehicle with flashing lights?

Answer: B — Pull over and stop if it is safe to do so

When a driver sees an emergency vehicle with flashing lights, the appropriate action is to pull over and stop if it is safe to do so. This action allows the emergency vehicle to pass freely and helps ensure the safety of both the emergency responders and any nearby motorists. Stopping creates a clear passage for the emergency vehicle, which may be responding to an urgent situation where time is of the essence. Additionally, it demonstrates awareness and respect for the law, as many jurisdictions require drivers to yield to emergency vehicles. In situations where the roadway is too narrow or stopping poses a hazard, drivers should be cautious and utilize good judgment about how to safely navigate around the emergency vehicle without obstructing its path. This response aligns with the regulations and best practices of driving in the presence of emergency vehicles.
