Driver G has had several drinks but walks and talks normally. Which statement about Driver G's ability to drive is true?

Correct answer: Vision, judgment and reaction can be impaired even with no outward signs.

Why

Alcohol is a drug that slows the brain and spinal cord. The Wyoming manual explains that it weakens all four steps of safe driving: identify, predict, decide and execute. Drinking drivers tend to fix their eyes on one object, lose side vision and judge distance poorly, and at 55 mph a drinking driver can travel 32 feet or more before braking. Many people show no outward signs at a high BAC, so looking or feeling fine does not mean a person can drive safely.
