FMCSA Makes Significant Increase to the Random Drug Test Rate for 2020

On Dec. 27, 2019, the Federal Motor Carrier Safety Administration (FMCSA) announced it is doubling the minimum annual percentage rate for random controlled substances testing for commercial motor vehicle (CMV) drivers. The current rate of 25% of the average number of driver positions has been increased to 50%.


  • The new testing rate went into effect Jan. 1, 2020.
  • The FMCSA is required to increase testing when data from a calendar year shows a reported positive rate of 1% or more. In 2018, the administration's Drug and Alcohol Testing Survey showed that positive results for controlled substances had increased to 1%.
  • The minimum annual percentage rate for random alcohol testing will not be changed in 2020 and will remain at 10%.
  • This announcement affects drivers of commercial motor vehicles (CMVs) who require a commercial driver's license.
