The Federal Motor Carrier Safety Administration (FMCSA) has announced that it will continue to require motor carriers to conduct random drug tests on 50% of their truck drivers and random alcohol tests on 10% of their drivers in the year 2025. This regulation has been in place since 2020, following an increase from the previous requirement of 25% for random drug testing of commercial vehicle drivers.
These percentages are set by the FMCSA, while the Pipeline and Hazardous Materials Safety Administration has determined that the minimum random drug testing rate for its covered employees will also be set at 50% for the calendar year 2025. This adjustment means that carriers are required to randomly test one out of every two drivers they employ.
Recent Regulations on Drug and Alcohol Testing
According to the FMCSA, the administrator is mandated to increase the minimum annual random testing percentage if the data from any calendar year shows a positive rate of 1.0% or higher. The performance-based system allows for the adjustment of the testing rate based on the positive results reported.
The protocol for deciding whether to raise or lower the testing percentage was established by the FMCSA’s final rule on “Controlled Substances and Alcohol Use and Testing,” published in 2001. The rule specifies that changes to the percentage rate will depend on the overall positive test rate for controlled substances within the trucking industry, as reported by employers.
Brenna Lyles, senior director of safety policy for the American Trucking Associations, commented on the decision to maintain the 50% testing rate. She noted that the regulations allow the threshold for random drug testing to drop below 50% only if positive test results are less than 1% of all industry drug tests for two consecutive years. Given the high frequency of positive marijuana tests and the increasing trend of refusals to undergo testing reported to the Drug and Alcohol Clearinghouse, a decrease in the testing threshold is unexpected.
Lyles emphasized the importance of continued diligence to ensure safety within the industry and on the highways.
Challenges in Reducing the Testing Rate
Thomas Bray, senior business adviser and editor at J.J. Keller & Associates, explained the performance-based nature of the FMCSA’s testing requirements. He noted that carriers are required to submit annual surveys through the Management Information System report, which contains data on their drug and alcohol testing from the previous year.
The FMCSA reviews these reports to determine the national positive rate for drug and alcohol tests. Bray pointed out that if the positive rate falls below 1% for two consecutive years, the testing rate could be reduced to 25%. However, with recent positive rates hovering around 1.1% to 1.2%, the testing rate remains at 50%. This means a carrier with 300 drivers would need to conduct 150 random tests over the next 12 months.
