What is the proper distance to keep from a fire hydrant while parking?

Answer: C — 15 feet

The proper distance to keep from a fire hydrant while parking is 15 feet. This distance is important for ensuring that emergency services can access the hydrant quickly in case of a fire. Fire hydrants provide crucial water supply for firefighting, and if a vehicle is parked too close, it could hinder the ability of fire personnel to connect hoses and operate the hydrant effectively. Keeping a distance of 15 feet allows for enough space for firefighters to maneuver and access the equipment they need without obstruction. It is also a common standard across many regions, including Arizona, to promote safety and efficiency during emergencies. Following this rule also helps drivers avoid citations or penalties associated with obstructing access to fire hydrants.
