Which technique ensures safety when a high-voltage power line is on a vehicle?

When a high-voltage power line is on a vehicle, it is crucial to prioritize the safety of everyone involved. Keeping passengers calm and inside the vehicle is the safest course of action because the vehicle acts as a shield from electrical current. The metal structure of the vehicle can provide a safe zone, as long as no part of the vehicle is in contact with the ground or any conductive materials that could create a path for electricity.

Encouraging passengers to jump out of the vehicle poses a significant risk, as doing so can create a pathway for electrical current to travel through their bodies, which can result in severe injury or death from electrocution. Attempting to move the vehicle carries similar risks—if the driver comes into contact with the vehicle while grounded, they could also be injured. Using a fire extinguisher on downed lines is not advisable, as it is not designed to deal with live electrical wires and may exacerbate the situation, leading to more hazards.

By ensuring passengers remain calm and inside the vehicle until professional help arrives, you minimize exposure to electrical hazards and allow time for emergency responders to evaluate and manage the situation safely.
