DOT Random Drug Testing Percentage Rate Increase (2020)

DOT Random Drug Testing

50% increase for DOT random drug testing

Each year, the FMCSA evaluates the rate of positive testing results for controlled substances. Depending on the reported figures, they modify their testing percentage rates.

For 2020, according to the FMCSA’s notice of program change, the testing percentage rate for controlled substances has increased to 50% of the average number of driver positions.

This new testing rate increase affects drivers of commercial motor vehicles (CMVs) requiring a commercial driver’s license (CDL).

Final rule regarding DOT random drug testing rates

When the number of positive tests for controlled substances in a calendar year increase to equal or greater than 1%, the FMCSA must also increase the minimum annual random testing percentage rate.

The rates increase on January 1 of the following calendar year. This accounts for a delay in application of this final rule to a full year after results are reported.

The results of the 2018 FMCSA Drug and Alcohol Testing Survey showed a 1% increase in the rate of positive tests for controlled substances. As a result, the percentage rate for DOT random drug testing increased from 25% to 50 % of the average number of driver positions. This increase went into effect on January 1, 2020.

The testing rates for alcohol will remain the same, which is 10% of the average number of driver positions.

Increased testing rates equals increased industry cost

It is estimated that the cost of additional testing will add between $50 to $70 million more to industry costs.

With the new 2020 testing rate, approximately 2.1 million random controlled substances tests will be conducted, doubling from the previous years’ 1.05 million tests.
