These requirements apply to both interstate and intrastate operations whose drivers are subject to the commercial driver’s license requirements found in Part 383 of the Federal Motor Carrier Safety Regulations.
The drug and alcohol testing requirements are very extensive, as you will see on the following pages. For that reason, we would suggest that small carriers join a drug and alcohol testing program and/or consortium. Such programs/consortiums will usually provide all necessary materials and help to ensure compliance.
| Table 3.1: REQUIRED TESTS FOR DRUGS & ALCOHOL | |
| Drug Tests | Pre-Employment, Post-Accident, Random, Reasonable Suspicion, Return-to-Duty, and Follow-Up. |
| Alcohol Tests | Post-Accident, Random, Reasonable Suspicion, Return-to-Duty, and Follow-Up. |
