DOT drug testing program setup for small fleets

Every motor carrier with CDL drivers must maintain a written DOT drug and alcohol testing program. We help small trucking companies put the right pieces in place — policies, consortium enrollment, random pool, supervisor training guidance, and reasonable suspicion procedures.

Which drivers are covered

A driver is generally a "covered employee" under FMCSA 49 CFR Part 382 if they operate a commercial motor vehicle that requires a CDL. This typically includes vehicles with a GVWR of 26,001 lbs or more, vehicles designed to transport 16+ passengers, and vehicles transporting placardable hazardous materials.

Required testing situations

Pre-employment

A negative DOT drug test result is generally required before a driver first performs a safety-sensitive function.

Random

Drivers must be in a random testing pool that meets FMCSA's minimum annual random testing rates.

Post-accident

Required after certain DOT-recordable accidents — typically those involving a fatality, citation plus injury, or citation plus tow-away.

Reasonable suspicion

Triggered when a trained supervisor observes specific indicators of drug or alcohol use.

Return-to-duty & follow-up

Required after a driver completes the return-to-duty process with a Substance Abuse Professional (SAP).

Employer responsibilities

The employer remains responsible for compliance with 49 CFR Parts 40 and 382.

We help you set this up and stay on top of it.
