When a driver is under the influence of marijuana, which driving behavior is most likely?

• A. Focus on multiple tasks at once while driving
• B. Drive faster with less attention
• C. Tend to concentrate on one thing at a time while driving
• D. React unpredictably to traffic signals

Answer: (C)

Marijuana slows processing and reduces the ability to divide attention between tasks while driving. Driving safely requires scanning for hazards, monitoring speed and signals, and responding to changing conditions all at once. With marijuana impairment, attention tends to narrow, so a driver is more likely to focus on one thing at a time rather than effectively multitasking. That makes concentrating on a single task the most likely behavior. The other patterns—multitasking easily, driving faster with less attention, or reacting unpredictably to signals—don’t align as consistently with marijuana’s effects, which typically involve slowed processing and reduced divided attention.
