As programs gain resources, they should expand to include older age groups because adults are also at risk for head injury. Bicycle riders should wear helmets whenever and wherever they ride a bicycle. Additional research is needed on the biomechanics of bicycle helmets before more definitive recommendations for biomechanical standards can be made. However, despite differences in helmet design, wearing an approved helmet is better than wearing no helmet at all. Furthermore, all standards emphasize that a helmet that has sustained an impact should be returned to the manufacturer for inspection or be destroyed and replaced.
Laws are most effective when combined with educational programs.
