Tick, tick, boom! Don’t bomb out on your 2023 random testing
The calendar year is winding down, and motor carriers must ensure they complete enough DOT random drug and alcohol tests by December 31st to meet the minimum annual testing rates.
Failing to drug and alcohol test at the applicable annual rates consistently shows up each year in the top 20 critical violations found during audits — with a potential fine of $18,170.
What are the 2023 testing rates?
By the end of 2023, those who operate commercial motor vehicles (CMVs) that require a commercial driver’s license (CDL) must complete:
- Drug tests that equal at least 50 percent of the average number of CDL positions for the year.
- Alcohol tests that equal at least 10 percent of the average number of CDL positions for the year.
You are permitted to test at a higher rate as best practice.
End-of-year shortfalls
If you test at the minimum rates or have a lot of missed tests, you could come up short at the end of the year.
Examples that may leave you shy of meeting your annual testing rates include:
- Drivers who are not notified of testing due to an extended leave or termination;
- Canceled tests, at no fault of the motor carrier or driver, that do not count toward the annual testing rate; and
- Failure on the part of the motor carrier to notify selected drivers.
If you are behind on your random tests, your last selection of the year must be higher than usual to compensate for the missed tests. In a worst-case scenario, a supplemental draw might be needed after the last selection of the year to reach your goal.
