Do I need extension mirrors when towing?
Regulations say that you should have mirrors to provide an adequate view to the rear and along both sides of your trailer.
With a small camping trailer or a narrow trailer such as some horseboxes it’s unlikely you’ll need extension mirrors. However, with many car and caravan combinations, including folding tourers, the view through your normal car mirrors will be obstructed, hence you will need to fit additional exterior mirrors.
The mirrors should be ‘e-marked’ to show they meet current standards. Don’t forget the regulations state your mirrors must not extend beyond your car or trailer by more than 200mm (250mm for cars registered from 2010) so once you go back to driving solo the extension mirrors need to be removed.
