Other Research Which Should Not Be Ignored in Current Underride Rulemaking

NHTSA, in the Preliminary Regulatory Evaluation of the NPRM issued in December 2015 for Rear Underride on Trailers, requested information about underride guard crash tests at higher speeds (than the 35 mph currently being proposed). This is what they said,

We recognize, however, that benefits may accrue from underride crashes at speeds higher than 56 km/h (35 mph), if, e.g., a vehicle’s guard exceeded the minimum performance requirements of the FMVSS. NHTSA requests information that would assist the agency in quantifying the possible benefits of CMVSS No. 223 rear impact guards in crashes with speeds higher than 56 km/h (35 mph)See: NPRM Rear Impact Guards, Rear Impact Protection December 2015 document; A Summary of Some of the Highlights

Here are some additional links to underride research around the world which should be taken into consideration when developing improved underride designs and standards.

  1. Evaluation of Energy Absorbing Pliers Underride Guards for Rear and Sides of Large Trucks
  2. DEVELOPMENT OF NEW UNDERRIDE GUARDS FOR ENHANCEMENT OF COMPATIBILITY BETWEEN TRUCKS AND CARS
  3. NHTSA NCAP #00248 Truck Underride Guard (Quinton Hazell Guard)

These links supplement the more lengthy list of underride research, which I posted previously here: Underride Roundtable To Consider Underride Research From Around the Globe.
