[QUOTE=Poly;493239]s75 of the Road Traffic Act 1988 (Road Traffic Act 1988
) does indeed make it illegal to supply an unroadworthy vehicle for use on the road. There are some get outs, and the rules for trade seller are slightly different from private ones but either way watching someone hook up a dodgy trailer to their car would probably ruin the defence.
This is simply to have the law in words and allow it to be argued. The seller's defence would simply be that it was not intended for use on the road as they had clearly stated. The fact that the buyer turned up with no means of legally removing the purchase does not put the blame on the seller.
Caveat Emptor.....Buyer beware. Still holds water (pardon the pun). There is no defence for knowingly buying an unroadworthy vehicle and then using it on the highway. In this case, "I've just bought it and been told it's OK" simply DOES NOT hold water.
