do i need towing mirrors with a van
Towing mirrors. You must have an adequate view of the road behind you. If your caravan or trailer is wider than the rear of the towing vehicle, you may need to fit suitable towing mirrors.If you tow without proper towing mirrors you can be: 1  prosecuted by the police.y Doblo has very large van/like mirrors and when I am hitched to my caravan I can see perfectly down the side (top to bottom). My only worry is that the law appears to be a bit of a grey area and the last thing I want is to get points/fine because there was something in the law I wasn't aware of.
