Under IRC Section 4481, a federal excise tax applies to the use of heavy vehicles on public highways. Repair shops are not directly liable unless they operate such vehicles, but must ensure compliance if offering services tied to taxable use. Most standard auto repair services (e.g., passenger vehicles, light trucks) are not subject to federal excise tax.
Applies to all employers with employees. Auto repair shops must comply with hazard communication (chemicals like solvents, brake cleaners), respiratory protection (if sanding or painting), machine guarding, and emergency action plans.

Under Clean Air Act Section 608, all technicians who handle refrigerants must be certified by an EPA-approved program.
