Not so Pat, you can drive your car home after a test, even if it fails, you can then only take it back to the garage to get a re-test after the work has been carried out, the Ministry centre's are only for HGV's and PSV's as they now will not allow petrol powered vehicles onto site. There are only allowed to check items that they can see without dismantling anything, if the master cylinders are hidden under the engine cover, they are not allowed to remove it, it will only fail on rust or corrosion if the affected area is within 12 inches on a load bearing structure, including seatbelt mountings. MOT's are now being changed to four years for brand new vehicles, and will soon be changing to every two years for all other PLG vehicles under the European directive, goods vehicles and PSV will still need to be checked every years
