Commercial Truck Driver DUI

Commercial Driver BAC Limit

A commercial driver may not report for or remain on duty with an alcohol concentration of 0.04 or greater under 49 CFR 382.201, half the 0.08 limit for other drivers. 49 CFR 392.5 goes further: a driver may not use alcohol within four hours before duty or have any measured alcohol concentration while on duty, and a driver who violates that rule is placed out of service for 24 hours. NHTSA found that 2% of large-truck drivers involved in fatal crashes in 2019 were alcohol-impaired, with a BAC of .08 or higher.

Post-accident testing remains the carrier’s obligation when the truck driver was not given a breathalyzer at the scene. A carrier that failed to arrange the required tests, or tested and is concealing the results, faces discovery on those records.

Carrier Failures Behind Impaired Truck Driving

A carrier that ignores warning signs, skips required testing, or puts an impaired driver back behind the wheel bears direct liability for what happens next. Impaired commercial driving rarely happens in isolation: behind almost every DUI truck case is a carrier that failed its obligations and often knew the risk existed. Carrier failures include:

• Failure to conduct reasonable suspicion testing when supervisors observed warning signs
• Incomplete or falsified drug and alcohol testing records
• Hiring a driver with a known history of substance abuse violations without required SAP (Substance Abuse Professional) clearance
• Ignoring prior DUI convictions or CDL disqualifications that should have prevented hiring
• Returning a driver to safety-sensitive functions before completion of required return-to-duty testing

CDL Disqualification and Punitive Damages

Under 49 CFR 383.51, a first conviction for driving a commercial vehicle under the influence disqualifies the driver for one year, and a second conviction disqualifies the driver for life. Under 49 CFR 391.15, the driver is also disqualified from driving for a motor carrier for one year, or three years for a second offense within three years. State criminal charges run parallel to these federal consequences. In the civil case, disqualifications and prior violations are strong evidence of both the driver’s negligence and the carrier’s knowledge of the risk.

Punitive damages under KRS 411.184 require clear and convincing evidence of oppression, fraud, or malice. A carrier answers for punitive damages based on its driver’s conduct only if it authorized, ratified, or should have anticipated that conduct, which is where a carrier’s ignored warning signs and skipped testing become evidence.
