- Bicycle helmet laws (date enacted): Countries compared by the date in whcih bicycle helmet laws were enacted. It must be noted that the laws vary greatly from country to country. In some, the helmet is only compulsory for children, while in others the factor taken into account is the type of way in which the bycicle is used. In South Africa, use of the helmet is compulsory for everyone, but the law isn't enforced. In Spain, it's compulsory in interurban ways, except when going uphill or in very hot weather.
