Indiana Fleets • Dry Van, Reefers, and Equipment Trailers
A straightforward PM checklist for keeping trailers safe, compliant, and out of the breakdown lane.
Trailers do not complain the way power units do. They quietly take abuse until a light is out, a wire is hanging, or a hub fails on the road. A simple, repeatable PM checklist catches most of those problems long before the DOT officer or the trooper behind you does.
At minimum, every trailer PM should include a full light check, plug condition, breakaway and ABS function where equipped, safety chains or gladhand seals, and a close look at wiring for rub-through or amateur repairs. Underneath, hubs, bearings, seals, and brake components tell the real story of how that unit has been treated.
The goal of an on-site trailer PM is two-fold: keep the unit safe for whoever is pulling it and keep it ready to pass a roadside inspection without drama. Photo documentation and clear notes tied to the unit number give owners and safety managers confidence that the work was actually done, not just checked on a clipboard.
