The Department of Transportation is the Federal agency that regulates all modes of transportation as well as pipeline and hazardous materials safety in the United States.  As part of this regulation, DOT requires substance abuse testing and has very specific guidelines on how, when and why this testing is completed.  These guidelines are found in 49 CFR Part 40.  Each agency of the Department of Transportation, such as FMCSA, FTA, FRA, FAA, and PHMSA, has agency specific guidelines that must be followed by companies and agencies as well.

Compliance with the Department of Transportation regulations are critical to the well being and sustainability of your company.  Failure to comply with regulations can result in hefty fines and the potential for a Federal order to cease and desist all operations.  Carolina Testing works closely with its clients to insure that all aspects of the regulations as it pertains to 49 CFR Part 40 are being followed.
