Seats and wheelchair anchorages fitted to a minibus shall be fixed to the vehicle.
A seat, other than a wheelchair, fitted to a minibus shall not be less than 400mm wide, and in ascertaining the width of a seat no account shall be taken of arm-rests, whether or not they are folded back or otherwise put out of use.
A minibus shall not be fitted with an anchorage for a wheelchair in such a manner that a wheelchair secured to the anchorage would face either side of the vehicle.
A minibus shall not be fitted with a seat—
facing either side of the vehicle and immediately forward of a rear door unless the seat is fitted with an arm-rest or similar device to guard against a passenger on that seat falling through the doorway; or
so placed that a passenger on it would, without protection, be liable to be thrown through a doorway which is provided with a power-operated door or down steps, unless the vehicle is fitted with a screen or guard which affords adequate protection against that occurrence.
