NHTSA delays heavy‑truck seat‑belt deadline

The National Highway Traffic Safety Administration has proposed giving heavy-truck manufacturers three more years to comply with part of a 2024 seat-belt rule, reopening a regulatory timeline that had been set to take effect in 2027. The proposal, published June 26 in the Federal Register, would move the compliance date to Sept. 1, 2030, for vehicles with a gross vehicle weight rating above 4,536 kilograms, or 10,000 pounds. NHTSA said it reconsidered the 2024 rule after receiving a petition from the Truck and Engine Manufacturers Association. ### What exactly did NHTSA change? The June 26 proposal does not rewrite federal seat-belt use laws for truck drivers. It changes the compliance date tied to Federal Motor Vehicle Safety Standard No. 210, the rule covering seat-belt assembly anchorages. NHTSA said the 2024 final rule updated test procedures for existing test devices and added an alternative test device as a compliance option. (federalregister.gov) The proposed delay applies only to vehicles above 10,000 pounds GVWR. For vehicles at or below that threshold, NHTSA said the compliance date would remain Sept. 1, 2027. For multi-stage manufacturers and alterers of lighter vehicles, the compliance date would remain Sept. 1, 2028. The agency said voluntary early compliance would still be allowed. (federalregister.gov) ### Why are heavy trucks being treated differently? NHTSA said the change follows a petition for reconsideration filed after the Sept. 17, 2024 final rule. The agency identified the petitioner as the Truck and Engine Manufacturers Association and said it was responding to issues raised in that filing by proposing a later deadline for heavier vehicles. (federalregister.gov) The Federal Register notice frames the move as a timing adjustment, not a retreat from the underlying standard. NHTSA left the lighter-vehicle dates in place while proposing a separate schedule for heavier trucks, which indicates the agency sees the compliance burden as different across weight classes. That is an inference from the structure of the proposal, based on the agency’s published dates and vehicle categories. (federalregister.gov) ### Does this affect fleets already operating trucks? The proposal is aimed at manufacturers’ compliance with vehicle equipment standards, not at day-to-day enforcement against drivers currently on the road. The Federal Register notice addresses how future vehicles must meet the anchorage rule and when those compliance obligations begin. (federalregister.gov) For fleets, the practical effect is that equipment planning tied to new-vehicle specifications may get more time if the proposal is finalized. NHTSA has not finalized that extension yet; it is still taking comments. ### Where does the rule stand now? The proposal is an NPRM — a notice of proposed rulemaking — and not yet a final rule. (federalregister.gov) NHTSA said comments must be received by July 27, 2026. The docket number is NHTSA-2025-0048, and the agency directed commenters to submit through Regulations.gov or by mail, hand delivery or fax. The next concrete step is the close of that comment period on July 27. After that, NHTSA can decide whether to finalize the Sept. 1, 2030 deadline for heavy vehicles, modify the proposal, or leave the 2027 date in place. (federalregister.gov)
