What is one reason for maintaining the trip ticket after an incident?

Maintaining the trip ticket after an incident is important primarily because it serves as a record of the vehicle's condition and any relevant details up until the point of the incident. This documentation is crucial until the necessary repairs are completed, as it provides a clear account of any pre-existing issues or the state of the vehicle. It helps ensure accountability and assists in determining the extent of damage post-incident. Additionally, the trip ticket can help in verifying maintenance records and following up on repairs, ensuring that any issues are properly addressed before the vehicle is put back into service.
