What drugs are commercial drivers tested for?

The substances covered by an FMCSA-mandated panel and the scope of any hospital toxicology test depend on the testing program and rules in effect. An attorney can compare the actual test with the applicable requirements and any medications relevant to driving ability.

Federal Drug and Alcohol Testing Requirements

FMCSA rules may require testing in circumstances such as pre-employment screening, qualifying post-accident events, random programs, reasonable suspicion, and return-to-duty or follow-up monitoring. The exact requirement depends on the driver's role, the event, and the rule in effect.

Commercial-driver alcohol standards and testing procedures can differ from those applied to non-commercial motorists, so the records should be evaluated under the applicable rule rather than a general assumption.

Evidence Used to Evaluate Impairment

Drug and Alcohol Testing Records: Available testing and Clearinghouse records may bear on compliance and driver status.
Pre-Employment Screening: The review may ask whether required testing and queries occurred.
Post-Crash Toxicology: Available blood or urine results require interpretation in context.
Carrier Compliance: Records may show whether the carrier maintained the testing program required for the driver.
Driver History: Relevant prior records may matter if the carrier knew or should have known about them and they are legally discoverable.

Testing RecordsSome post-crash testing rules use event-specific collection periods. Whether a missed or delayed test matters depends on the rule, circumstances, and other evidence.
