The U.S. DOT issued a memo in 2012 stating that marijuana use remained off-limits for truck operators, following referendums in California and Washington that legalized marijuana outright. Responding to queries from Overdrive in November 2016 (following successful legalization votes in more states) and again this month, the DOT says its stance hasn’t changed. Any changes to federal drug testing policy for truck drivers would need to start with the White House’s Office of National Drug Control Policy, the DOT said.
Even drivers operating exclusively intrastate within states that have legalized marijuana are still subject to federal drug screening requirements, including random drug tests, says Rajkovacz. “The feds dictate to the states that [drivers] must do this to drive a commercial vehicle. It’s a federal requirement to operate a vehicle above 26,000 pounds — you have to be in a drug testing program.”
