Drunk & Drugged Truck Driver Accidents

Commercial drivers are legally impaired at a 0.04% blood alcohol concentration, half the 0.08% limit for other drivers. They may not use alcohol within 4 hours of going on duty (49 CFR 392.5). Carriers must run drug and alcohol testing, including post-accident testing, and check the FMCSA Drug & Alcohol Clearinghouse. Impaired driving can support punitive damages in Texas.
