Worker Impairment and Liability (Drugs, Alcohol, Fatigue, Stress)

ASP written lesson, 11 min read. ASP Domain 9: Legal

Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.

What you'll learn

  • Describe DOT alcohol prohibitions and testing types for commercial drivers
  • Apply hours-of-service limits to a driver's day
  • Explain what the ADA allows employers to do about illegal drug use and alcohol
  • List Drug-Free Workplace Act elements for federal contractors
  • Explain why drug-testing and reporting policies must not deter injury reporting

What this lesson covers

The federal rules that shape how employers handle worker impairment: Department of Transportation (DOT) drug and alcohol rules for commercial drivers, hours-of-service limits for fatigue, the Americans with Disabilities Act (ADA) on drugs and alcohol, the Drug-Free Workplace Act and the OSHA anti-retaliation rule. Impairment in a safety-sensitive job is a hazard, and the response has legal limits.
