🚲 Can I ride a bike without a helmet?

With conditions

Quick answer

It depends on the road and your age. A helmet is mandatory when cycling on interurban roads for all cyclists, and on any road, including in town, for under-16s. In town, for adults, wearing a helmet is voluntary but strongly recommended. There are specific exceptions on interurban roads (e.g. long climbs, extreme heat or accredited medical reasons). Cycling without a helmet when it's mandatory is fined. E-scooters follow different rules (often municipal), separate from bicycle rules.

📋 The rules

Interurban: helmet mandatory for everyone
Under-16s: helmet mandatory also in town
Town, adults: voluntary but recommended
Set exceptions (long climbs, heat, medical reasons)
E-scooter: own rules, separate from the bicycle

🔓 Exceptions

Long climbs, extreme heat or accredited medical reasons on interurban roads
Municipal bylaws may add local rules
Other equipment (lights, reflectors) has its own obligations

⚠️ Penalties & fines

Cycling without a helmet when it's mandatory (interurban road, or under-16s on any road) is a traffic offence fined 200 euros. If the cyclist is a minor, the responsibility falls on the parents or guardians. Beyond the fine, the helmet reduces the risk of serious injury in a fall or collision, so authorities also recommend it for adults in town, where it isn't mandatory. Always wear it properly fastened and approved.
