Fleet Vehicle Preventive Maintenance Checklist [FREE PDF]

FMCSA regulations under 49 CFR Part 396 require motor carriers to systematically inspect, repair, and maintain all commercial motor vehicles under their control. Preventive maintenance (PM) programs reduce roadside inspection failures, out-of-service orders, and liability exposure while meeting federal and state safety requirements. A documented PM checklist supports compliance during FMCSA compliance reviews and state DOT audits.
