What UN Regulation No. 13 - Braking Systems for Heavy Vehicles (M, N, O Categories) requires
UN Regulation No. 13 (UNECE WP.29) is the international uniform standard for braking systems on heavy-duty motor vehicles and trailers (Categories M2, M3 buses; N1-N3 trucks; O1-O4 trailers); it specifies performance requirements for service brake, secondary brake, and parking brake, mandates Anti-lock Braking Systems (ABS) for vehicles over 3.5 tonnes, establishes Electronic Braking System (EBS) requirements, and defines braking compatibility between trucks and trailers - forming the mandatory type approval framework for commercial vehicles in 57 UNECE contracting states.
