MINIBUS operators will complain this week to the Transport Department about what they say are unreasonable demands imposed in annual vehicle inspections.
They claim that an increasing number of vehicles have been rejected due to the change in the colour scheme.
This meant an extra inspection fee of about $500 and the loss of a day's business to attend the Kowloon Bay Motor Vehicles Examination Centre.
Public Light Bus Trade Union representatives will meet department officials on Friday.
Union chairman Ng Mau-shing said the examiners had become unreasonably demanding.
He said there was a lack of guidelines for the examiners and operators after the new colour scheme for more than 4,500 public light buses in the territory was implemented at the beginning of the month.
The scheme is designed to let mini-bus operators carry more advertising by moving the line on the middle of the vans' bodies to above their windows.
