What is the leading cause of motor vehicle related deaths and injuries?

The leading cause of motor vehicle-related deaths and injuries is alcohol. Numerous studies and statistics have consistently shown that driving under the influence of alcohol significantly impairs cognitive and motor skills, which increases the likelihood of accidents. Alcohol consumption can lead to decreased reaction times, impaired judgment, and reduced coordination, which are all critical factors in safe driving.

While other factors such as excessive speed, distracted driving, and fatigue also contribute to motor vehicle accidents, the impact of alcohol is particularly pronounced due to its ability to severely compromise a driver's ability to operate a vehicle safely. Public health campaigns and legal measures, such as DUI laws, have been implemented to address the dangers of driving while intoxicated, indicating the significant societal recognition of alcohol's detrimental role in road safety.
