FAQ
DOT Compliance Questions
General answers about DOT drug and alcohol testing. For requirements specific to your operation, please call us.
49 CFR Part 40 is the U.S. Department of Transportation regulation that sets the procedures for drug and alcohol testing across all DOT-regulated industries. Each DOT agency (such as FMCSA) adds its own rules for who is tested and when.
We support employers regulated by FMCSA, FAA, FRA, FTA, PHMSA, and the USCG, all of which follow the Part 40 testing procedures.
DOT testing can be required for pre-employment, random selection, reasonable suspicion, post-accident situations, return-to-duty, and follow-up testing, as defined by regulation. Please call for more information about your specific obligations.
The FMCSA Drug and Alcohol Clearinghouse is a federal database of drug and alcohol program violations for CDL drivers. FMCSA-regulated employers are required to run Clearinghouse queries as part of their compliance program. Please call for more information about your query requirements.
The Medical Review Officer is a licensed physician who reviews and verifies drug test results before they are reported, protecting the integrity and confidentiality of the process.
