Drug & Alcohol Testing

Drug & Alcohol Testing

Managing a DOT Drug and Alcohol Testing Program can be complex. Between random selection requirements, test scheduling, employee records, and audit documentation, it’s easy for compliance gaps to appear. Our in-house DOT Compliance Team, MROs, and nationwide testing network make it easy to stay compliant and audit-ready — without adding to your workload.


If you fall into one of the following jurisdictions the DOT requires you to be a part of a Drug and Alcohol Testing Program or Consortium.

Federal Motor Carrier Safety Administration (FMCSA)
Federal Aviation Administration (FAA)
Federal Railroad Administration (FRA)
Federal Transit Administration (FTA)
Pipeline and Hazardous Materials Safety Administration (PHMSA)
United States Coast Guard (USCG)

This is where CNS and our partners CNS Occupational Medicine come in. Our comprehensive Drug and Alcohol Consortium Administration Services (C/TPA) are available for companies that are regulated by Federal and State governments.
