DOT Drug & Alcohol Testing for Transportation Employers
Stay audit-ready. Avoid costly violations. Protect your operating authority.
We manage DOT-compliant testing programs for safety-sensitive employers, including random consortium management, Clearinghouse compliance, and full audit documentation support.
DOT-Regulated Employers
Fully managed DOT drug & alcohol testing programs designed to keep safety-sensitive employers compliant with U.S. Department of Transportation regulations across highway, aviation, rail, transit, and pipeline industries. Includes pre-employment, random, post-accident, reasonable suspicion, and return-to-duty requirements.
Non-DOT Employers
When people hear that DOT drug testing is highly regulated, they sometimes assume non-DOT drug testing is less important. For many employers, a well-designed non-DOT drug testing program is one of the most important steps they can take to protect employees, reduce risk, and put safety first.
