It is very simple why our failure rate is high,most of our failures are due to lights/bulbs out,Have a look on the system and it shows what the failure rate is on each item.I am in Spain at the moment so no access to MOT system,will check when i get back and post the FULL facts.
I have had an ITV done on my vehicle here in Spain,Facillitys are government run with a drive through system,the presenter can drive the vehicle through themselves as i did.Its a DIFFERENT test,to my mind not as thorough as ours
