4. Bike helmet legislation could make cycling safer
   04-17-2007 · EurekAlert!
   Legislation that requires people to wear bicycle helmets appears to increase use and decreases injury rates, according to the results of a Cochrane Review. Cycling is a popular pastime and a mode of transport for children, but it also leads to many injuries that are frequently sufficiently severe to require hospitalisation. This is a global problem, and particularly effects low-income countries where the proportion of cycle-users is high.
