What Is FMCSA Drug and Alcohol Testing Rule 382.201?
FMCSA drug and alcohol testing rule 382.201 states that a driver cannot report for duty or remain on duty requiring the performance of safety-sensitive functions while having an alcohol concentration of 0.04 or greater.
The regulation applies to commercial drivers who operate vehicles requiring a CDL under FMCSA jurisdiction.
Safety-sensitive functions include activities directly related to operating and controlling a commercial motor vehicle.
The purpose of FMCSA drug and alcohol testing rule 382.201 is to improve highway safety by reducing impaired driving risks among commercial drivers.
What Does Rule 382.201 Say?
The regulation generally provides:
A driver shall not report for duty, remain on duty, or perform a safety-sensitive function with an alcohol concentration of 0.04 or greater.
This federal requirement establishes a stricter standard than most state DUI laws because commercial drivers are held to higher safety expectations.
Commercial truck drivers can face consequences even when alcohol concentrations remain below standard legal driving limits for passenger vehicles.
Who Must Follow FMCSA Drug and Alcohol Testing Rule 382.201?
FMCSA drug and alcohol testing rule 382.201 applies to drivers operating commercial motor vehicles requiring a CDL.

- Hazardous material transporters
The rule generally applies whenever drivers perform safety-sensitive duties.
What Are Safety-Sensitive Functions?
Under FMCSA regulations, safety-sensitive functions include activities involving direct responsibility for commercial vehicle operation.
Examples include:
Driving a Commercial Motor Vehicle
Operating a truck or commercial vehicle on public roads.
Waiting to Be Dispatched

Inspecting Equipment
Pre-trip inspections and vehicle checks.

Follow-Up Testing
Additional testing may continue after return-to-duty requirements.
Testing programs help enforce FMCSA drug and alcohol testing rule 382.201 compliance.
What Happens If a Driver Tests 0.04 or Higher?
If a commercial driver records an alcohol concentration of 0.04 or greater:
- Immediate removal from safety-sensitive duties
- Out-of-service status
- Required substance abuse evaluation
- Return-to-duty process requirements
- Possible employment consequences
- Potential FMCSA reporting obligations
Motor carriers must remove drivers from duty immediately.
What Happens If Alcohol Concentration Is Between 0.02 and 0.039?
FMCSA rules also address lower alcohol concentrations.
If a driver tests between:
0.02 and 0.039
The driver generally cannot continue performing safety-sensitive functions for at least 24 hours.
Although below the 0.04 violation threshold, drivers may still be temporarily removed from duty.
This requirement exists to support commercial transportation safety standards.
