As we know, from May cars over 40 years old that have not been substantially altered do not have to undergo an MOT test. However, owners can voluntarily put their cars through an MOT should they so wish - which seems like a good idea to me. But the question I can’t seem to get answered is this: If you do put your car in voluntarily and it fails, what position does that put you in? Are you still allowed to drive the car on the road (and renew your free tax) should you choose not to get the work done immediately? At present, if your car fails, you can only drive it to and from a garage for a repair/re-MOT. Does the same apply if you have voluntarily taken it in? In other words, is that fail reported to you only or is the DVLA informed?
