How far should a vehicle be parked from a fire hydrant?

Answer: B — 15 feet

A vehicle should be parked at least 15 feet away from a fire hydrant to ensure that firefighters have adequate access to the hydrant in the event of a fire. This distance allows for the necessary room to operate the hydrant and connect hoses without obstruction. Maintaining this distance is crucial for public safety, as any delay in accessing water can hinder firefighting efforts. Being aware of the proper distance not only complies with local laws but also promotes the safety of the community by ensuring that emergency services can respond effectively when needed.
