Title 49 › Subtitle SUBTITLE VI— MOTOR VEHICLE AND DRIVER PROGRAMS › Part B— COMMERCIAL › Chapter 313— COMMERCIAL MOTOR VEHICLE OPERATORS › § 31310
A driver of a commercial motor vehicle is considered to be driving under the influence when their blood alcohol level is .04 percent or higher. The Secretary of Transportation must take away a person’s commercial driving privileges for at least 1 year for a first offense like driving a commercial vehicle under the influence of alcohol or drugs, leaving the scene of a crash, using the vehicle in a felony, driving while the commercial license is revoked/suspended/cancelled for a CMV reason, or causing a death by careless or criminal driving. If the vehicle was carrying hazardous materials that must be placarded under section 5103, the minimum ban for those first offenses is 3 years. A person can lose their commercial driving rights for life for repeat offenses (two or more of the offenses above), for certain drug- or human-trafficking felonies involving a commercial vehicle, or for other combinations of serious violations. The Secretary can make rules to reduce a life disqualification to no less than 10 years in some cases. Two serious traffic violations in 3 years means at least 60 days off the road; three in 3 years means at least 120 days. The Secretary may order up to 30 days off immediately for an imminent hazard, and longer after notice and a hearing. States’ own disqualifications count, so the Secretary does not always have to act if a State already did. The Secretary must also set rules for 24-hour out-of-service orders for certain violations, require drivers to report those orders to their employer and licensing State, and impose penalties: first out-of-service violation is at least 180 days off and at least $2,500 fine; a second is at least 2 years and up to 5 years off and at least $5,000 fine. Employers face civil fines up to $25,000 for knowingly allowing violations, and a willful violation can bring up to one year in jail or a criminal fine. Rules also require at least a 60-day disqualification for certain railroad-highway crossing violations and allow employer fines up to $10,000. Foreign commercial drivers are subject to these disqualifications too.
