Ends the federal overtime exemption for workers covered by the Department of Transportation’s motor carrier hours‑of‑service rules. This means truck and bus drivers and certain helpers, loaders, and mechanics who were previously excluded from federal overtime would become eligible for time‑and‑a‑half pay after 40 hours in a workweek under federal law.

The measure does not add replacement language or specify when it takes effect. Employers in trucking, bus, and related motor carrier operations would likely need to reclassify affected employees, track hours, and pay overtime going forward, while DOT safety rules would continue to apply separately.
