What should be avoided until a vehicle's system is fully deactivated?

The correct answer is to avoid cutting the steering column until a vehicle's system is fully deactivated. This is crucial because the steering column may be integrated with electronic systems that can become hazardous if tampered with while the vehicle is still active. For example, cutting the steering column may inadvertently trigger airbag deployment or affect the function of other electronic components that are still receiving power.

In general, ensuring that a vehicle's systems are completely deactivated helps in reducing the risk of injury to first responders, occupants, or bystanders during the extrication process. Properly following protocols for deactivating all vehicle systems, such as disabling the battery and ensuring the vehicle is in a safe state, is essential to prevent unexpected hazards.
