23. How is truck driver drug or alcohol use handled?

Truck driver drug or alcohol use is taken very seriously because it can directly contribute to accidents and catastrophic injuries. Commercial drivers in the U.S. are subject to federal regulations under the FMCSA, which strictly prohibit operating a commercial vehicle under the influence of alcohol or controlled substances. If a truck driver is found to be impaired, it can serve as strong evidence of negligence in an accident case, significantly strengthening the claim for compensation. Law enforcement may conduct field sobriety tests, blood or urine tests, or review post-accident toxicology reports to determine impairment.

When a truck driver is found to be under the influence, it can also impact liability and insurance coverage. Trucking companies can be held responsible under the legal theory of “respondeat superior,” meaning they may be liable for the actions of their employees performed within the scope of employment. Insurance companies often treat alcohol- or drug-related crashes differently, and in some cases, policies may have clauses limiting coverage if the driver was grossly negligent or intoxicated. This makes prompt investigation and documentation crucial for building a strong case.

From a legal standpoint, evidence of drug or alcohol use can also influence punitive damages in addition to compensatory damages. Punitive damages are designed to punish particularly reckless behavior and deter similar conduct in the future. Attorneys handling truck accident claims will often request driver records, DOT logs, toxicology reports, and maintenance or training records to determine whether the company failed to properly screen, train, or supervise the driver. This combination of evidence can significantly increase the value of a personal injury or wrongful death claim.
