How does marijuana use impact a driver's ability?

Marijuana use significantly impairs a driver's ability to operate a vehicle safely, particularly affecting their ability to stay in their lane. When someone consumes marijuana, it can alter their perception, reaction times, and motor coordination. This impairment can lead to issues such as drifting out of lanes, difficulty judging distances, and slower response to changes in traffic conditions.

The effects of marijuana on cognitive functions can interfere with decision-making and attention, which are crucial for safe driving. Studies have shown that drivers under the influence of marijuana are at a higher risk of being involved in accidents due to these impairments. Therefore, the impact of marijuana on a driver’s ability to stay in their lane is a significant concern for road safety.
