It screens a urine sample for five classes of drugs: Marijuana (THC), Cocaine, Amphetamines (including MDMA), Opioids (like heroin, codeine, morphine, oxycodone), and Phencyclidine (PCP).<\/p>\n<h3>What happens if you refuse a DOT drug test?<\/h3>\n<p>Refusing a test is treated the same as failing one. You will be immediately removed from all safety-sensitive duties. You will not be allowed to return to duty until you have completed the full return-to-duty process with a Substance Abuse Professional (SAP), just as if you had tested positive.<\/p>\n<h3>Can a CDL driver be fired for a first-time failed drug test?<\/h3>\n<p>Yes. While the DOT rules require you to be removed from driving duties, they do not require your employer to fire you. However, most company policies have a zero-tolerance rule, and a failed test is often grounds for immediate termination. This is up to the individual employer.<\/p>\n<hr \/>\n<h2><b>Want to actually drive like a pro?
