This has been covered a few times on here re what does & what does not need an IVA test before using it on the road.
After a discussion on FB I asked the DVSA (VOSA) for their ruling on what does & what does not need an IVA test.
The reply has some good & some bad news.
First the good news.
If you start with an existing approved trailer as a complete base then altering its type from say flat bed to box trailer DOES NOT need an IVA as long as the trailer part is not altered. It was thought that large alterations did need a test if the "type" of trailer was changed. Its akin to a fixed load.
Just using the axle & a few old parts etc would not count.
Now the bad news.
1, As most people already thought building a new trailer of any type does need an IVA.
2, Making a trailer out of another vehicle type (car or van) always needs an IVA.
