July 6, 2022 – In its long-awaited rule on truck underride protection, the National Highway Traffic Safety Administration (NHTSA) appears to be out of sync with the Safe System strategy adopted by the U.S. Department of Transportation (DOT) earlier this year.
While the new standard is an improvement over the old one, nearly all newly manufactured guards on trailers already meet this new standard, which is similar to a longstanding Canadian requirement. Meanwhile, IIHS crash testing and the TOUGHGUARD award inaugurated in 2017 have pushed the largest trailer manufacturers to strengthen their underride guards well beyond this level, demonstrating that further improvements are feasible.
To truly reduce the number of lives lost in underride crashes, NHTSA needs to incorporate changes that would require crash testing of guards when mounted on trailers, allow fewer exemptions for other kinds of trucks and improve protection in offset crashes. The Safe System strategy, if it is to be more than words on paper, requires NHTSA to take all these steps.
