Statistics show that the number of serious or fatal injuries is still high. To reverse this trend, new regulations from the UN’s Economic Commission for Europe (ECE) were implemented in 2019-2021. To get approval under the new regulations, manufacturers must build rear impact guards that can absorb roughly double the test force for trucks (classes N2, N3 over 3.5 t) or trailers (classes O3, O4 over 3.5 t) compared with the old directive.
These stricter ECE R58 03 regulations was fully implemented in September 2021. Vehicle body builders will need to equip newly registered commercial vehicles with rear underrun protection devices and rear impact guards that comply with this regulatory update.
In terms of strengthening safety performance in the U.S., the Federal Motor Carrier Safety Administration (FMCSA) required starting in December 2021 that rear impact guards be inspected annually for commercial motor vehicles.
With the right RUPD design and Strenx® steel, fleet owners and bodybuilders can comply with ECE R58 regulations, while getting a better strength-to-weight ratio compared with aluminum.
