An MOT test isn't required before the IVA test, but I decided it was a good trial run and meant I could drive it legally to a test centre and get some initial items checked before IVA including emissions and brakes. I also took the opportunity to check the speedo against a sat nav on the way up to the local garage. With the Sat Nav showing 30mph I knew my speedo needed tweaking as it was showing under 30mph. For IVA the speedo must read more than the true speedo at 30, 40, 50, 60, and 70mph.
The MOT passed once the headlight had been adjusted!
