The Federal Motor Carrier Safety Administration (FMCSA) has lowered the minimum random controlled substances testing rate from 50 percent to 25 percent of the average number of commercial motor vehicle driver positions for calendar year 2016.
The change was made in response to three consecutive years of industry-wide random positive test rates below a 1 percent threshold. The FMCSA estimates fewer tests will save U.S. motor carriers $50 million a year.
The 25 percent random testing minimum corresponds with percentages applied to other U.S. Department of Transportation (DOT) agencies. The minimum random alcohol-testing rate remains at 10 percent.
Under FMCSA rules, random testing applies to the commercial motor carrier industry, Consortium/Third Party Administrators (C/TPAs) and employees who are required have a commercial driver’s license to operate:
Operators and drivers are advised to check with their state transportation agency for any additional definitions of commercial motor vehicles in their jurisdiction.
The FMCSA administrator has the discretion to decrease the random testing minimum based on reported positive random test rates in the motor carrier industry. The 25 percent minimum reflects positive rates below 1 percent from 2011-2013. Based on an industry survey, the estimated positive random controlled substance test rate in 2013 was 0.7 percent.
In accordance with 49 CFR, Part 382.305(e)(2) on Controlled Substances and Alcohol Use and Testing, the FMCSA administrator will raise the minimum random test rate to 50 percent of all driver positions if the reported positive rate for any calendar year is 1 percent or more.
