Impaired, Distracted, and Aggressive Driving
Core Concepts
Impaired driving covers alcohol, drugs (including prescriptions and cannabis), and fatigue. In Arizona, a driver is impaired at a blood alcohol concentration of 0.08 percent for those 21 and older; commercial drivers face a lower threshold, and any detectable level can support an impaired-to-the-slightest-degree charge. For those under 21, the state enforces a zero-tolerance standard. Teach students that impairment begins before legal limits and that time, not coffee or cold showers, is the only way to sober up. Distracted driving includes visual, manual, and cognitive distraction; texting combines all three. Arizona law restricts handheld phone use while driving. Aggressive driving includes tailgating, weaving, cutting off, and road rage; teach de-escalation, not confrontation.
Common Traps
Questions test the difference between “legal limit” and “impaired to the slightest degree” - you can be arrested below 0.08. Watch for myths: coffee, food, and cold air do not lower BAC. Distraction questions often reward the answer that removes the distraction entirely, such as pulling over to text or setting navigation before driving. Aggressive-driving questions reward avoiding eye contact and creating distance.
Rule of Thumb
If a driver shows any sign of impairment - weaving, slow response, erratic speed - increase following distance, do not attempt to pass aggressively, and report it. For yourself, the safe answer is always: do not drive after drinking or using impairing substances, and plan a ride before you go out.
