Safe & Responsible DrivingStandalone practice
An adult with a valid Missouri medical marijuana card uses marijuana and then feels only slightly affected. May the person drive?
Correct answer: No, because legal use does not make impaired driving legal
Why
Marijuana can slow reaction time, distort judgment of time and distance, and cause lane weaving. It is the drug most often cited in crashes after alcohol, and using both together is even more dangerous. If you have used marijuana, arrange another ride.
