  4. According to the Montana Driver Manual, which of these counts as one alcoholic drink?

    • A A 12-ounce glass of wine
    • B A 5-ounce glass of wine
    • C Two 12-ounce cans of commercial beer
    • D A 3-ounce glass of 80-proof liquor
    Show answer

    B. A 5-ounce glass of wine

    The manual counts one drink as 12 ounces of commercial beer, a 5-ounce glass of wine, or 1-1/2 ounces of 80-proof liquor. Each holds about the same alcohol, so a glass of wine is not safer than a beer. Craft beers and specialty drinks can hold more than one drink's worth.
