DOT alcohol testing isn't one-size-fits-all. Knowing which DOT-approved method to use—and when—can save your business from compliance headaches and costly penalties.
Here are the main DOT-approved alcohol testing methods and their best uses:
• **Breath Alcohol Test (BAT):** The standard choice for most pre-employment, random, reasonable suspicion, and post-accident testing. It's fast, accurate, and federally approved.
• **Evidential Breath Testing (EBT):** Used by trained technicians with certified devices. Required for all DOT alcohol tests to ensure precision and legal defensibility.
• **Saliva Testing:** Occasionally used as an initial screening method but not DOT-approved for definitive testing.
• **Urine Testing:** Not accepted by DOT for alcohol testing but used for drug screening.
Choosing the right method means understanding your testing scenario and DOT regulations. For example, random testing programs rely heavily on breath tests with EBT devices to meet federal standards.
