49 U.S.C. § 31303 — Notification requirements

(a) Violations — A commercial driver who holds a state-issued license and breaks a state or local traffic law (other than a parking violation) must tell their employer about it. If the violation happened in a state other than the one that issued the license, the driver must also notify an official the issuing state has designated. Either notice must happen within 30 days of being found to have committed the violation. (b) Revocations, Suspensions, and Cancellations — If a state revokes, suspends, or cancels an employee's driver's license, or the employee loses the right to drive a commercial motor vehicle in a state for any length of time, or is disqualified from driving one for any length of time, the employee must tell their employer within 30 days of that action. (c) Previous Employment — When applying for a job driving a commercial motor vehicle, an applicant must tell the prospective employer about their previous jobs driving commercial motor vehicles, at the time of the application. The Secretary of Transportation sets, by regulation, how far back that disclosure must go — but it can never be less than the 10 years right before the application.
