When may a fire apparatus be driven over a downed power line?

A fire apparatus should never be driven over a downed power line due to the significant hazards involved. Downed power lines can still carry electrical current, posing a serious risk of electrocution to both the vehicle occupants and any nearby personnel. The best practice in such situations is to maintain a safe distance from the downed line and to wait for utility companies to respond and deal with the hazard.

Driving over a power line, even if precautions are taken or conditions seem favorable, can result in catastrophic consequences. It's essential for firefighters to prioritize safety and follow established protocols to prevent accidents and injuries when dealing with electrical hazards. The focus should always be on ensuring safety first, which is why the correct stance is that a fire apparatus should never traverse over fallen power lines.
