Who completes designated portions of the SF-91 after the vehicle operator?

The correct response is that the vehicle operator's supervisor completes designated portions of the SF-91 after the vehicle operator. This practice follows the standard protocol for accident reporting and documentation within military and federal operations. The supervisor’s involvement is crucial as they ensure that all aspects of the report are completed accurately and comprehensively, reflecting any relevant observations or comments regarding the incident.

The supervisor may have additional context about the vehicle's operation, maintenance history, or the location of the incident, enhancing the accuracy and integrity of the report. They play a vital role in verifying details that the vehicle operator may have noted and ensuring that the report meets all necessary regulatory requirements.

Other roles involved, such as the investigating officer or dispatcher, do have important functions in the overall accident reporting process. However, it is specifically the supervisor who follows up on the operator's report and provides authoritative input regarding the operational status and accountability of the vehicle and its operator in the context of the incident.
