Safe & Responsible DrivingStandalone practice
You took an allergy pill that can cause drowsiness. At dinner, a friend offers you one glass of wine, and you plan to drive home after the meal. What is the safest choice?
Correct answer: Do not drink, because the pill and the alcohol can multiply each other's effects.
Why
Drugs can react with each other and multiply the harm to your concentration and coordination, and the danger is greatest when one of them is alcohol. The combination can also cause serious health problems, even death. Oklahoma DUI law covers driving under the combined influence of alcohol and another substance, even when your alcohol level is below 0.08.
