While not actually illegal, hanging decorations from your rear-view mirror or using stickers to jazz up your car is not permitted by the Highway Code and Road Traffic Act if it obstructs your view of the road in any way. You could receive an on-the-spot fine of £100 and three penalty points if a dangling air freshener or fluffy dice prevents you from having a full view of the road. It could also affect your insurer paying out if you’re involved in an incident. The Road Traffic Act states ‘no person shall drive a motor vehicle on a road if he is in such a position that he cannot…have a full view of the road and traffic ahead.’ Likewise, ‘Windscreen and windows must be kept clean and free from obstructions to vision.’ The same applies to fans, large sat-navs and even using the navigation on an iPad. Missing something because you had a large air freshener obscuring your view is dangerous. Good driving involves exceptional observation skills and seeing things early allows you to anticipate and plan how to deal with hazards.
