Passing target: 20/25 correct (TLA practice target)
Safe & Responsible DrivingStandalone practice
You begin drifting in your lane and struggling to stay alert during a drive. What is the safest response?
Correct answer: Stop at a safe place and rest, or change to an alert qualified driver.
Why
Do not push through drowsiness. Stop safely to rest or change drivers. Caffeine may give a short-lived benefit, but it does not reliably prevent microsleeps in a sleep-deprived driver. Plan enough sleep before driving.
