How long after a change is made in the size of certain parts in the drive system, should the taxi meter be calibrated?
- Correct answer: Within forty eight hours.
- Twenty four hours only.
- Not more than half a year before the date of the periodic adjustment of the meter.
- One week from the date in which the repair was finished.
Why this is the answer
The correct answer in the official bank: Within forty eight hours.
The taxi meter calculates distance from the rotation of the wheels and the drive system. When the size of drive-system parts or tyres changes, the meter no longer measures distance accurately, so passengers could be charged the wrong fare. That is why it must be calibrated within forty eight hours, rather than waiting for the periodic adjustment.
