Bicycle helmet laws by country

The wearing of bicycle helmets and attitudes towards their use vary around the world. The effects of compulsory use of helmets are disputed (see Bicycle helmet laws). Only the four countries of Argentina, Cyprus, Australia, and New Zealand currently both require and enforce universal use of helmets by cyclists. In some other jurisdictions partial rules apply, 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.
