No person shall park within how many feet of a fire station?

The correct answer is 20 feet. The regulation regarding parking near a fire station is designed to ensure that emergency vehicles can exit the station quickly and safely without obstruction. By requiring that vehicles not be parked within 20 feet of a fire station, this distance provides enough clearance for fire trucks to maneuver out of the station. This rule is crucial for public safety, as it allows for rapid response times to emergencies.

Parking too close to a fire station could impede the movement of emergency response vehicles, potentially causing delays that could endanger lives or property. The distance of 20 feet has been determined to strike an effective balance between allowing regular parking while ensuring safe and convenient access for emergency services. This rule is generally well-established in traffic laws to enhance overall community safety.
