Commercial DUI Truck Accident Lawyers
Commercial truck drivers face a stricter BAC limit of 0.04% — and carriers face their own legal obligations for testing and oversight. When either fails, our dedicated trucking team pursues full accountability.
Commercial truck drivers are held to a stricter legal standard than passenger vehicle drivers. Under 49 CFR 392.5, a commercial driver is prohibited from driving with a blood alcohol concentration (BAC) of 0.04% or higher — half the 0.08% limit for regular drivers. The NHTSA found that 2% of large truck drivers in fatal crashes had a BAC of 0.08% or higher, while the FMCSA found 3.1% had a BAC of 0.01% or higher. When a carrier ignores warning signs, fails to conduct required testing, or puts an impaired driver back behind the wheel, the company bears direct liability for what happens. Our dedicated trucking team pursues the full picture of accountability.
Federal Alcohol and Drug Testing Requirements for Commercial Drivers
The FMCSA’s drug and alcohol testing program (49 CFR Part 382) requires commercial carriers to test drivers in these specific situations:
When Federal Law Requires Testing
- Pre-employment — mandatory drug test (negative result required before driving); optional alcohol test
- Random testing — carriers must maintain a random testing program; minimum 50% of drivers tested for drugs and 10% for alcohol annually
- Reasonable suspicion — when a trained supervisor observes signs of impairment: slurred speech, erratic behavior, odor of alcohol or drugs
- Post-accident — required following crashes involving fatalities, citations, or vehicles being towed. Drug test within 32 hours; alcohol test within 8 hours.
- Return-to-duty and follow-up — after a driver tests positive and completes a substance abuse treatment program

How Carriers Enable Impaired Driving
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. Our investigation targets:
- 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
Consequences of CDL DUI — and Why They Matter for Your Case
Under 49 CFR 391.15, commercial drivers face mandatory CDL disqualification for DUI — one year for a first offense, lifetime for a second offense. State criminal charges run parallel to federal regulatory consequences. In your civil case, these disqualifications and prior violations are powerful evidence of both individual driver negligence and carrier knowledge of the risk.
When a carrier put an impaired driver on the road in willful disregard of federal testing requirements, Kentucky courts may allow punitive damages — additional compensation designed to punish the carrier and deter others from the same conduct. Our team builds these aggravated damages cases when the facts support them.
Post-accident testing matters. If the truck driver was not given a breathalyzer at the scene, federal rules still required the carrier to arrange drug and alcohol testing within prescribed time windows. If the carrier failed to do so — or if they did test and are concealing the results — our team’s discovery process will uncover it.

Frequently Asked Questions
What is the legal BAC limit for commercial truck drivers in Kentucky?
Under federal law (49 CFR 392.5), commercial drivers are prohibited from operating with a BAC of 0.04% or higher — half the 0.08% limit for regular drivers. A commercial driver with a BAC between 0.01% and 0.039% faces a 24-hour out-of-service order. Driving a commercial vehicle with any detectable alcohol is a serious violation.
What if the driver wasn’t tested at the scene?
Federal regulations required the carrier to arrange post-accident drug and alcohol testing within specific time limits — alcohol testing within 8 hours, drug testing within 32 hours. If the carrier failed to arrange testing or if results were concealed, that failure is itself evidence of negligence and may raise an inference that testing was avoided for a reason. Our team pursues this through discovery.
Can I sue the trucking company, not just the driver?
Yes — and in most DUI truck accident cases, the carrier is the more important defendant. Carriers are liable for failing to test, hiring drivers with known substance abuse histories, ignoring warning signs, and returning drivers to duty before they complete required treatment programs. The carrier also typically carries far more insurance than the individual driver.
Are punitive damages available in commercial DUI crash cases?
Potentially, yes. When a carrier’s conduct shows conscious disregard for the safety of others — such as ignoring prior DUI violations, bypassing required testing, or retaining a driver whose impairment was known — Kentucky law allows the jury to award punitive damages beyond compensatory damages. These are assessed case-by-case but are a significant tool in egregious situations.
