We service all major trailer types for commercial carriers, fleet operators, and owner-operators across East Texas.
How Often Should I Have My Trailer Inspected?
Regular trailer inspections are crucial for safety and performance. Ideally, trailers should be inspected at least annually, or every 12,000 miles. However, for heavy-duty usage or in extreme conditions, more frequent checks are advisable to prevent unexpected breakdowns and costly repairs.

Trailer DOT Inspection & Compliance
For commercial carriers, trailer DOT compliance isn't optional - and an out-of-service violation costs far more than a preventive inspection. Hex 6 performs annual DOT safety inspections for all trailer types and handles all required repairs to bring your trailer into compliance.
Common DOT deficiency areas we repair:
- Brake adjustment and chamber replacement
- Lighting deficiencies - marker lights, stop/tail/turn, clearance lights
- Tire and wheel end defects
- Structural damage to frames and crossmembers
- Kingpin and fifth wheel wear
- Mud flap violations
After repairs are complete, we provide full documentation for your compliance records. If your trailer has been placed out of service, call us — we'll get it inspected, repaired, and back on the road.
How Often Should My Trailer Be Inspected?
At minimum, commercial trailers should receive a thorough inspection annually - this aligns with DOT annual inspection requirements for interstate commerce. For trailers in heavy use or extreme conditions, more frequent checks are advisable.
Recommended intervals:
- Pre-trip (every use): Lights, tires, brakes, coupling, cargo securement
- Every 25,000–30,000 miles: Brake adjustment, wheel bearing inspection, lubrication service
- Annually: Full DOT safety inspection, structural inspection, electrical system check
Trailers that sit idle for extended periods need inspection before returning to service - seals dry out, brakes can seize, and rodents can damage wiring in ways that aren't visible without a proper check.
Fleet Trailer Maintenance Programs
For carriers and fleet operators running multiple trailers, keeping every unit inspected, compliant, and road-ready is a full-time logistics challenge. Hex 6 works with fleet operators to build maintenance schedules that keep your trailers out of the shop and on the road.
Our Fleet Advantage program offers:
- Reduced labor rates on all trailer maintenance and repairs
- Personalized maintenance schedules aligned to your trailer types and mileage
- Priority scheduling to minimize time out of service
- Full maintenance records accessible through our online portal
- Dedicated account support - one contact who knows your fleet
