Crash Fatality Rates After Recreational Marijuana Legalization in Washington and Colorado. Evaluate motor vehicle crash fatality rates in the first 2 states and compare them with motor vehicle crash fatality rates in similar states without recreational marijuana legalization.

The U.S. Department of Transportation report suggests that while cannabis could potentially impair driving skills, its findings in other research suggest drivers under the influence of cannabis are actually more cautious. “Subjects in most of the simulator and instrumented-vehicle studies on marijuana are driving typically drive slower, follow other cars at greater distances and take fewer risks than when sober,” the report said.
