Oregon Trailer Brake Laws 2026: Performance Rule
State towing-law summaries are educational only and are not legal advice. Verify your trailer type, actual weight or GVWR, and equipment requirements with official Oregon sources before towing.
Quick answer: verified stopping-distance performance rule
In Oregon, the verified source set does not show a simple universal numeric trailer brake threshold. The state is modeled as a verified stopping-distance performance rule. Breakaway equipment and safety chains may also be required depending on trailer type, weight, and coupling. Always verify with official Oregon sources before towing.
