Establish a review process where a supervisor signs off on all DVIRs daily and initiates repair orders for any defects. DVIR records must be kept for at least 90 days.

Best Practice: Document every compliance action with date, responsible party, and outcome. Documentation is your defense during South Carolina Highway Patrol audits.
