Which statement best describes the overall risk of drinking and driving?

• A. It has no effect on driving.
• B. It makes you more alert.
• C. It increases crash risk due to impaired coordination, judgment, and reaction time.
• D. It only affects vision.

Answer: (C)

Alcohol impairs driving-related abilities. It slows your reaction time, reduces coordination, and dulls your judgment about speed, distance, and risk. With these impairments, you’re more likely to misjudge gaps, drift out of your lane, or fail to stop in time, increasing the chance of a crash. Vision and perception can be affected too, but the dangerous combination of slower processing, poorer motor control, and poorer decision-making is what raises crash risk. The other statements don’t fit because they either claim no effect, increased alertness, or only vision is affected, whereas alcohol affects multiple skills essential to safe driving.
