Alcohol, Drugs, Fatigue, and Rider Impairment
Impairment Is the Leading Killer
Alcohol and drugs impair judgment, balance, and reaction time, and motorcycle riders are especially vulnerable because they have no protective cage. Arizona law prohibits riding with a blood alcohol concentration at or above the legal limit, and riding under the influence of drugs, including some prescription medications, is illegal. Test questions often stress that the only safe choice is not to ride after drinking; coffee, food, or time alone does not reliably sober you up.
Prescription and Over-the-Counter Drugs
Many medications cause drowsiness or slow reactions. Read labels and ask a pharmacist before riding. Combining alcohol with any drug multiplies impairment.
Fatigue and Heat
Fatigue slows reactions as much as alcohol. In Arizona heat, dehydration and heat exhaustion can impair riding. Plan breaks, hydrate, and stop when you feel drowsy or unfocused. If you feel sleepy, pull over safely and rest; do not push through.
Recognizing Impairment in Yourself and Others
Watch for weaving, wide turns, delayed reactions, and inability to stay in a lane. If a friend is impaired, take the keys, call a ride, or let them stay. The safe answer on any test is to avoid riding when impaired and to intervene for others.
Rule of thumb: if you have been drinking or feel impaired, do not ride. There is no trick that makes impaired riding safe.
