A taxi driver that is obliged to wear eyeglasses or any other optical instrument:
- Must hold an extra pair of eyeglasses or contact lenses at the taxi station.
- Must ensure that he carries on him a pair of eyeglasses or contact lenses while driving during the night.
- Must ensure that he carries on him a pair of eyeglasses or contact lenses while driving during the day.
- Correct answer: Must carry with him an extra pair of eyeglasses or contact lenses while driving.
Why this is the answer
The correct answer in the official bank: Must carry with him an extra pair of eyeglasses or contact lenses while driving.
A taxi driver who needs glasses or contact lenses must wear them whenever driving, day or night. On top of that, he must carry an extra pair while driving, so that if his glasses break or get lost he can still drive safely with passengers. A spare pair left at the taxi station is useless out on the road, and the duty is not limited to day or night.
