Commercial Drivers License Exam Prep

Answer: D - When compared, one to the other, a 1.5 ounce shot of 80 proof liquor, 12 ounces of 5% beer, and five ounces of 12% wine all have the same amount of alcohol. This may surprise some people, as many believe that hard liquor has far more alcohol than beer or wine. Driving under the influence can cost any driver their license, but this is especially true for commercial vehicle drivers. Many states have very strict laws concerning alcohol levels for commercial drivers, which are often lower than legal limits for non-commercial drivers.
