2018 PHMSA minimum random rates increased.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is increasing its minimum random drug testing rate to 50 percent during calendar year 2018. The drug testing rate for 2017 was 25 percent.

The increase is due to an increased rate of positive tests in 2016, this higher rate will stay in effect until the nationwide annual rate of positives decreases below 1 percent.
