Answer :

Final answer:

Alcohol plays a significant role in fatal crashes among young drivers aged between 15 and 20. It affects motor skills, cognitive functions, and judgment significantly making driving hazardous. The metabolism of alcohol in humans can further amplify these effects with heavy consumption.

Explanation:

The specific figures related to the percentage of crashes involving alcohol that result in fatalities among 15 to 20-year-olds can vary by area and over time, but it is widely recognized that alcohol is a significant factor in such accidents. According to data from organizations like Mothers Against Driving (MADD), the presence of alcohol increases the likelihood of severe and often fatal consequences in crashes. Alcohol impairs a driver's reaction time, visual acuity, and behavioral control, greatly increasing the risk of causing an accident.

The metabolism of alcohol in the human body is also relevant here as it might help explain why the impact of alcohol on driving ability can be so severe. In both men and women, alcohol metabolizes at a certain rate which can be slowed down or sped up depending on various factors. However, with excessive consumption, alcohol can induce complete lack of consciousness, memory loss during periods of intoxication, and heavily impaired judgment and decision-making abilities.
