I didnt want to cause any alarm, but it happens,
I take my cars to the same test station and they have a reception area with vending machines which overlooks the test area, they can drive it onto
the ramp and off, and that it.
Except if you have an VLSD you should have the brake test done on the road, so you need to allow them some wiggle room.
The brake test on mine was done in the small service area out side the MOT station, took about 2mins and in no way was it abused
