FTA Dear Colleague Letter 2019 Random Drug Testing Rate Increase

As mandated by its drug and alcohol regulation, FTA will increase the minimum rate of random drug testing from 25 percent to 50 percent of covered employees for employers subject to FTA’s drug and alcohol regulation, effective January 1, 2019. This change is due to an increase in the industry’s ‘‘positive rate’’ as reflected in random drug test data for calendar year 2017.
