What should an ambulance driver do when approaching a red light while responding to a call?

Answer: B — Come to a complete stop and proceed safely

When an ambulance driver approaches a red light while responding to a call, the appropriate action is to come to a complete stop and then proceed safely. This practice prioritizes safety for the ambulance crew, patients, and other road users. Stopping allows the driver to assess the intersection for potential hazards, such as other vehicles, pedestrians, or cyclists that may not yield despite the emergency vehicle’s presence. This action aligns with traffic laws that require emergency vehicles to stop at red lights to prevent accidents. After ensuring the intersection is clear, the driver can then proceed with caution. This responsible approach balances the urgency of responding to emergencies with the crucial need for safety and situational awareness to avoid collisions and ensure the safety of all road users. Other options, such as speeding through the intersection or ignoring the traffic signals, compromise safety and could lead to severe accidents or legal consequences. Waiting for a green light is impractical, as it would significantly delay the emergency response, but ensuring the intersection is safe after stopping is key.
