NHTSA Rejects Probe into Trailer Side-Crash Risks
Published Date: 4/1/2025
Notice
Summary
NHTSA said no to a request to investigate van-type semi-trailers for side crash dangers. They believe current rules and new projects under the Infrastructure Investment and Jobs Act already tackle these safety issues. This means no new investigations or costs for truck owners right now, but safety efforts keep rolling forward.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
No New Investigation for Box Trailers
NHTSA denied a petition (DP24-004) filed July 3, 2024 and opened August 26, 2024 asking the agency to investigate van‑type (box) semi‑trailers for side underride guard problems. Because the petition was denied, there will be no new NHTSA investigation and no immediate new compliance costs for truck owners right now.
Safety Work Continues via Rulemaking and IIJA
NHTSA said the side underride issues raised are best addressed through its recent rulemaking and ongoing projects under the Infrastructure Investment and Jobs Act (IIJA). That means safety improvements for van‑type semi‑trailers will proceed through existing rulemaking and IIJA activities rather than through a new defect investigation by NHTSA.
