Which of the following is commonly found in both impaired and fatally injured drivers?

The presence of marijuana is linked to both impaired and fatally injured drivers, as numerous studies have shown that it can significantly affect a person's ability to operate a vehicle safely. Marijuana can impair cognitive functions, motor skills, and reaction times, which are crucial for safe driving. In situations where drivers have been involved in accidents, analyses often find that marijuana use is prevalent among those who are either impaired or have sustained fatal injuries. Therefore, it's important to recognize the impact of marijuana on driving performance and the associated risks.

While other substances like alcohol, cocaine, and prescription medications also contribute to impaired driving and fatal accidents, marijuana's prevalence in these specific scenarios highlights the importance of understanding its effects on driving ability. This understanding is essential for promoting road safety and encouraging responsible use of substances that can impair motor skills.
