6.2.5 Disqualification of Drivers (383.51)

If an employer knows, or reasonably should know, that a driver is disqualified, it must not allow the disqualified driver to operate a CMV. See 49 CFR 383.37. The disqualification period of a driver is determined by the offense and the driver’s record of prior convictions. There are separate disqualification tables for the following types of offenses in 49 CFR 383.51: major offenses, serious offenses, railroad-highway grade crossing offenses, and violations of out-of-service orders. Major and serious offenses require driver disqualification even if the CDL holder is driving a non-CMV.

Disqualifying Offenses

Major offenses require a minimum disqualification of one year and include the following:

  • Driving under the influence of alcohol as prescribed by State law.

  • Causing a fatality through the negligent operation of a CMV.
  • Using the vehicle in the commission of a felony involving the manufacturing, distributing, or dispensing of a controlled substance (mandatory lifetime disqualification).

  • Speeding excessively (15 mph or more over the speed limit).
  • Driving recklessly.
  • Making improper or erratic traffic lane changes.
