Can I cycle without a helmet?
Yes for an adult, no for a child under 12. In France, the bike helmet is mandatory for children under 12, whether riding or as passengers (in a seat or trailer). For adults and those 12 and over, the helmet is strongly recommended but not mandatory — except specific rules (some events, tracks). The helmet must be fastened. Other useful or required gear depending on context: a reflective vest at night outside built-up areas, front/rear lights and a bell.

⚠️ Penalties & fines
Carrying or letting a child under 12 ride without a helmet is a 4th-class offence: €135 fine, charged to the adult accompanying or carrying the child. For an adult riding without a helmet there's no fine (not mandatory), but the helmet sharply cuts the risk of head injury in a fall. Missing lights or a vest at night is also fineable.
