What should be done before shutting off power to a vehicle?

• A. Lower windows and unlock doors
• B. Remove keys from ignition
• C. Disconnect battery
• D. Lower windows only

Answer: (A)

Before cutting power to a vehicle, the priority is to ensure anyone inside can exit and responders can access. Unlocking the doors and lowering the windows accomplishes this by removing entry barriers and providing a clear path for evacuation, as well as ventilation for heat and smoke. Lowered windows also improve communication with occupants and reduce the risk of entrapment if systems still hold power. Removing the keys or disconnecting the battery are useful safety steps, but they don’t directly guarantee immediate access or escape like unlocking doors and opening windows do.
