By law you must wear a safety helmet when riding a motorcycle on the road. All helmets sold in the UK must either:
comply with British Standard BS 6658:1985
comply with UNECE Regulation 22.05
comply with any standard accepted by a member of the European Economic Area
which offers a level of safety and protection equivalent to BS 6658:1985
Damage to helmets
If your helmet receives any serious impact you should always buy a new one. Damage won't always be visible to the naked eye. For this reason you should never buy a second-hand helmet.
Visors and goggles
A visor or goggles are vital to protect your eyes from wind, rain, insects and road dirt. All visors or goggles must comply with a British Standard and display a BSI Kitemark, or they must comply with a European standard which offers a level of safety and protection at least equivalent to the British Standard
If you need glasses or contact lenses to read a numberplate at the prescribed distance then you must wear your glasses or contact lenses when you ride. You should not wear tinted glasses, visors or goggles if you are riding in the dark or conditions of poor visibility.
It is very important that you keep your visor or goggles clean. You must have a clear view of the road ahead at all times. To clean your goggles or visor wash them with warm soapy water. Do not use solvents or petrol.
Visibility aids for motorcyclists
Many road accidents involving motorcyclists occur because another road user didn't see them. Using some form of visibility aid will help others to see you. Remember you need to be visible from the side as well as the front and back.
Wearing fluorescent orange or yellow clothing in daylight will improve your chances of being seen.
Other methods you could use to help other road users to see you in daylight include:
wearing a white helmet
wearing brightly coloured clothing
riding with your headlamp on dipped beam
To improve visibility in the dark you need to wear reflective material. They work by reflecting the light from headlamps of other vehicles. This makes you much more visible from a long distance away.
