Mobile Trailer Repair & Service
Trailer lights, air leaks, brakes, or landing gear causing trouble? Describe the trailer and its location, then confirm whether a provider can assess it safely on site.

Give a clear location and trailer brief
Gather details from a safe position. Follow your carrier's roadside procedures and applicable warning-device requirements.
- Share the highway, travel direction, exit or mile marker, and a location pin if available. Describe access restrictions and whether a lane is blocked.
- Give the commercial trailer type, length, make, and unit number. Say whether it is loaded, attached to a tractor, or parked separately.
- Describe what you observed: affected lights, ABS warning, audible air leak, brake symptoms, door, or landing-gear problem. Avoid guessing which part failed.
- Have the fleet repair-authorization contact and any defect or inspection report ready. Do not approach traffic or go underneath the trailer to collect information for a call.
Ask about the exact service
Ask whether the provider works on this trailer type and fault, can reach it safely, and has the necessary equipment and likely parts. Confirm whether the load and attached tractor affect access. A mobile visit may result in diagnosis or repair; ask what would require a shop, recovery, or another specialist.
Confirm charges and approval
Request the call-out fee, travel charges, diagnostic charge, labor minimum and rate, after-hours fees, and taxes. Ask about parts procurement or a second trip, accepted payment, fleet authorization, and what is owed for diagnosis alone. Agree that further work needs approval, and ask for an arrival estimate and delay updates.
Keep brake work with qualified hands
Do not attempt a brake adjustment or repair from this guide. Ask for a technician qualified for the specific task. FMCSA distinguishes limited brake-task qualification from qualification for other brake repairs. A service visit alone does not prove the trailer is compliant or ready to return to service.

FAQ
Sometimes. The fault, parts, technician qualifications, and work location determine the answer. Describe the symptoms and have the provider assess the next step.
Request an itemized invoice describing the diagnosis, completed work, parts, and unresolved defects. Ask your carrier and provider how applicable defect or inspection paperwork should be handled before returning to service.
