Rear Impact Guard Testing

Rear Impact Guards are required by Transport Canada and US D.O.T. to protect the driving public in the event of a collision at the rear of a trailer, heavy truck or other large vehicles. Requirements are clearly stated in the Federal and Canadian Motor Vehicle Safety Standards (FMVSS/CMVSS).


Standards Testing



  • CMVSS 223: Test Method 223 — Rear Impact Guard (December 2003) is to be used for demonstrating compliance with the requirements of Section 223 of Schedule IV to the Motor Vehicle Safety Regulations (MVSR).
