The American Transportation Research Institute is seeking motor carrier input on the impact of marijuana legalization on the trucking industry’s workforce. While many states have made its use legal, marijuana is still considered a Class 1 illegal drug at the federal level and its use is prohibited for safety-sensitive workers such as truck drivers.

This research was identified as a top priority in 2022 by ATRI’s Research Advisory Committee and will expand on ATRI’s 2019 study on the impacts of marijuana legalization on roadway safety.
Motor carrier staff and executives familiar with driver recruitment, retention and drug testing practices and trends are asked to share their input through the online survey. This research will provide insight into the specific challenges motor carriers face as the use of recreational marijuana grows in the U.S. The findings should also provide insight into approaches the industry can take to address these challenges, according to ATRI.
“States are moving quickly to legalize recreational marijuana use,” said Fred Fakkema, vice president of safety and compliance at Zonar Systems and chairman of the American Trucking Associations' Law Enforcement Advisory Board. “This rapid change directly impacts fleets and their workforce; ATRI’s research will help quantify those impacts.”
ATRI’s confidential survey is available online and will remain open through March 17, 2023.
