Bicycle helmet laws by country
Laws concerning the wearing of bicycle helmets vary around the world, (see Bicycle helmet laws). Five countries (Argentina, Cyprus, Australia, Namibia, and New Zealand) currently both require and enforce universal use of helmets by cyclists. Partial rules apply in some other jurisdictions, such as only for children (e.g. in France), in certain states or sub-national divisions (e.g. British Columbia in Canada), or under other limited conditions.
The effects of compulsory use of helmets are disputed.
