A 3-minute lesson from the Louisiana course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Many legal medicines can impair you as much as alcohol, and so can health conditions and aging. You're responsible for making sure you're fit to drive every single time.
Know the rule
Louisiana gives the same penalty for driving under the influence of drugs as for alcohol, including over-the-counter and prescribed medicine. Read medication labels.
Amphetamines, tranquilizers and barbiturates can cause drowsiness, poor coordination and risky judgment for hours. Combined with alcohol, their effects increase dramatically.
Marijuana can affect your eyesight and your judgment of time, speed and distance, and interferes with memory and learning. Combined with alcohol it's especially dangerous.
At every license issuance you answer three questions about your mental and physical health; answer honestly. If you must give up driving, a Louisiana ID card is available.
You took an over-the-counter allergy pill that warns it may cause drowsiness. It can impair you like alcohol, and Louisiana penalizes drugged driving the same as drunk driving. Don't drive until it wears off.
