Re: Retaxing vehicle on a SORN
Immaterial. You are not allowed to drive a vehicle on the continent without a valid tax disc. Similarly, your insurance may also be invalidated. Imagine a camper owner in France, it has no road tax, but makes a bee line for the runnel and arrives in Folkestone. If he 'comes to notice' here, his vehicle could be seized for not displaying a current disk. I saw this happen during a vehicle check on the A74 at Carlisle. The reasoning is it is a 'reciprocal' arrangement, you're vehicle is allowed free passage providing it meets the regulations pertaining to that country (plus any special local ones like toll-road billets and the like.
Spain too is doing the same with campervans blighting the shore in Tenerife, with many saying it will cost them too much to take the vehicle back to blighty for an MoT, but if parked on a public road, they get towed.
