Section 382.305 requires every motor carrier subject to Part 382 to implement a random drug and alcohol testing program. For 2026, the minimum random rates are 50% for controlled substances and 10% for alcohol.
What "implementing a program" means
- Enrollment in a Consortium / Third-Party Administrator, or operation of an in-house program with the same controls.
- Random selection process meeting the §382.305 specifications.
- Selections spread reasonably throughout the year.
- Tests administered as soon as possible after selection.
- Records retained per §382.401.
Severity weight
This is severity weight 10. Most new-entrant audit failures in the Controlled Substances and Alcohol BASIC are §382.305 issues — either no program at all, or a program with no selections in the prior 12 months.
How to comply
- Enroll in a C/TPA before your first driver runs a load.
- Confirm the C/TPA is performing random selections at the §382.305 rates.
- Retain the C/TPA agreement and selection records.
- Use the Random Pool Calculator to verify the test count against your pool.
