When are you allowed to park over a fire hydrant?

Parking over a fire hydrant is strictly regulated because it can obstruct access for emergency services when immediate access to water may be crucial for firefighting efforts.

Having someone capable of moving the vehicle stay with it implies that if an emergency arises, that person can quickly relocate the vehicle, allowing firefighters to access the hydrant without delay. This scenario is the only situation where parking over a fire hydrant could be considered acceptable, as it provides a safeguard against potential emergencies.

In contrast, other circumstances do not provide the same level of assurance that the hydrant will remain accessible for emergency services. Parking whenever it's convenient always poses a risk to public safety. Indicating that it's safe to do something does not account for the responsibilities drivers have regarding emergency equipment. The option stating it's permissible only in an emergency overlooks the fundamental rule that hydrants should always remain accessible. Thus, having someone present who can move the vehicle aligns with the principle of maintaining clear access to critical emergency resources.
