The American Transportation Research Institute in 2019 published research on marijuana legalization and impaired driving, and how it impacts highway safety. Now, four years later, ATRI has released new research about how marijuana legalization at the state level is impacting the trucking industry.
Joining Matt and Jason this week is ATRI Vice President Jeffrey Short, who talks about the study and its findings, including how legalization has impacted highway safety, the number of drivers disqualified because of marijuana since FMCSA’s Drug and Alcohol Clearinghouse took effect in 2020, and carriers’ and drivers’ perceptions of possible future changes to federal marijuana laws and more.
