When are cycling helmets particularly required by law in many states?

Cycling helmets are particularly required by law for adolescents in many states due to the heightened vulnerability of young riders. Adolescents, often less experienced and more prone to accidents, benefit significantly from the protection that helmets provide. Statistically, head injuries are more prevalent among younger cyclists, prompting legislation aimed at fostering safety. The laws are designed to encourage helmet use among this age group, as it is widely recognized that effective protective measures can prevent or mitigate serious injuries in the event of a fall or collision.

While some laws may also apply to adults or specific circumstances (such as competitions or rural riding), the specific focus on adolescents reflects a public health initiative aimed at reducing injury rates among younger populations. This targeted approach ensures that safety measures are in place for those most at risk.
