Remote pilots should refrain from operating until the effects of dizziness-causing medication have ___.

• A. The effects have fully worn off
• B. Worn off enough to be safe
• C. A physician approves flight
• D. Eight hours have passed

Answer: (B)

The main idea is you must be free from impairment caused by dizziness-inducing medication before flying. Medicines that cause dizziness can hurt your balance, coordination, vision, and reaction time, all of which are essential for safely controlling a drone and noticing hazards. So you should refrain from operating until the effects have worn off enough to be safe, meaning you feel clear-headed and capable of responding quickly.

This is the best choice because it accounts for individual variation and different medications—there isn’t a single fixed time that guarantees safety. Requiring the medication to be completely worn off is unnecessarily strict since some residual effects may be negligible and not impair flight. Needing a physician’s approval isn’t a standard requirement for drone operation, and a universal eight-hour rule doesn’t fit all medications or people. The key is ensuring you are safe to fly, not just that a certain amount of time has passed.
