A helmet has always been a necessary piece of kit for anyone riding a motorcycle. It is even more important now, because any helmet that complies with EU safety standards has to be fitted with a label, which will state that the helmet has been tested and is compliant with those safety standards. This label is usually somewhere on the rear of the helmet. Always check whether the helmet fits you properly, and whether it will protect you adequately. If the helmet is a new purchase, you should always wear it on a motorcycle before you write it off. You should also check that any helmet you buy will protect you adequately in the event of a crash. Helmets are designed to protect you against a variety of impacts. . They should always be worn firmly on the head, and the chinstrap should be fastened. Your helmet should be fitted to your head size, and you should have bought it from a reputable shop that can guarantee that it is in good condition.
