Seat belts & MOT? - ib33
I have removed one rear seat belt from my Citroen AX and fitted it to the drivers, due to the mechanism failing on the original. My question is will my car still pass the MOT with three seat belts fitted or do I have to remove the one remaining rear belt to pass?
Regards, Ian

If it was originally fitted with rear seat belts, it must have both in working order to pass. If it was not fitted with belts but they have been added, they must work. So yours will fail if it has any missing or non-working belt.
