Does Commercial Auto Insurance Cover Trailers?
Commercial auto often extends liability to certain trailers; physical damage is separate and weight limits may apply.
Often, a commercial auto policy extends liability to certain trailers, but the cited ISO form’s example is limited to trailers under 2,000 pounds. Physical damage may require separate coverage or scheduling. That is a form-specific example, not a universal rule for all trailers or all coverages. The form also treats trailer physical damage differently from liability arising from towing.
A heavier or specialized trailer may need to be scheduled, and a trailer used as equipment or for a business-specific operation can raise classification questions. Physical damage to the trailer is not established just because liability coverage follows a covered towing auto.
Give the insurer the trailer’s VIN, ownership, value, load capacity, use, and towing vehicles. Check whether the declarations list the trailer or use a symbol that includes it, whether collision and comprehensive apply, and whether attached equipment or cargo needs separate coverage.
