Which statement is true regarding the effects of alcohol on driving?

Alcohol consumption significantly impairs both motor skills and cognitive functioning, making option C the accurate statement. When a person drinks alcohol, it affects the central nervous system, leading to decreased coordination, slower reaction times, and impaired decision-making abilities. These impairments can prevent a driver from responding appropriately to dynamic driving situations, increasing the risk of accidents.

Motor skills, which include physical coordination and the ability to control a vehicle, are hindered by alcohol as it affects the brain regions responsible for these functions. Simultaneously, cognitive functioning, which involves judgment, problem-solving, and decision-making, is also diminished. This dual impairment significantly raises the likelihood of dangerous driving behavior.

In contrast, the other options present misrepresentations of alcohol's effects. They suggest that alcohol enhances abilities or has no impact, which contradicts extensive research and data confirming that alcohol detrimentally impacts both motor and cognitive functions essential for safe driving.
