Effective January 1, 2016, carriers must now randomly drug test at least 25% of the average number of driver positions (instead of the 50% that was previously mandated).
The FMCSA chose to reduce the annual percentage rate because the positive rate for controlled substances random testing fell below 1.0% for 3 consecutive calendar years (2011-2013). This is subject to change at the FMCSA’s discretion.
Businesses are reminded that the 2016 alcohol test minimum remains unchanged at 10% of the average population in each FMCSA pool.
What This Means to You
- Employers will be required to conduct fewer random drug tests in 2016 than in 2015.
- Companies operating more than one DOT number should establish a separate random testing pool for each.
