A trailer tire failure can leave debris, damage an adjacent dual, or affect how the combination tracks. Keep the combination controlled and stay away from the tire assembly until the scene is safe.
Keep the combination straight
Hold the wheel steadily and avoid abrupt steering or braking. A trailer failure can create sway or a pull that takes time to manage.
Reduce speed with control
Ease off and brake progressively as conditions allow. Follow your training, road conditions, and company emergency procedure.
Check the trailer’s position
Move to a safer shoulder or stopping area only when clear. Account for the trailer’s length, traffic beside it, and the possibility of debris.
Mark the stopped combination
Use hazard lights and place required warning devices at the appropriate positions when it is safe to exit and your procedures require it.
Stay away from the dual-tire area
Do not approach a damaged dual assembly casually. Tire and wheel components can remain hazardous after a failure; keep people clear until service arrives.
Describe the trailer tire to dispatch
Report trailer number, axle and side, tire size, highway direction, nearest marker, and whether the combination is fully out of the lane.
Why trailer failures need their own check
The tractor may feel different from a steer-tire failure, but the trailer can still sway, drag, or expose a second tire or wheel to damage. Tell dispatch whether the failed tire is on an outside or inside position, which axle and side are affected, and whether debris remains in the lane.
