Does my child have to wear a helmet on a bike?
Conditional — yes for children: a child under 16 must wear a bike helmet, but for adults it is not required. Under art. 79 of the Traffic Act no. 77/2019, a child under 16 must wear a bicycle helmet when cycling. This is the biggest trap in the topic: the internet and older sources routinely say "under 15", because the old regulation set it there — but with the new Traffic Act, which took effect on 1 January 2020, the duty was moved into statute and raised to 16. The only exemption is a medical certificate releasing a child from the helmet on health grounds. Police and guardians are to draw children's attention to the duty. For adults a helmet is not required but strongly recommended. The same under-16 helmet rule applies to e-scooters, so the limit is identical whether the child is on a bicycle or a small electric vehicle.
📋 The rules
- A child under 16 must wear a bike helmet when cycling under art. 79 of the Traffic Act no. 77/2019.
- The limit was raised from 15 to 16 and moved into statute with the new Traffic Act that took effect on 1 January 2020 — the older "under 15" figure is out of date.
- The only exemption is a medical certificate releasing the child from the helmet on health or medical grounds.
- Police and guardians are to draw children's attention to the helmet duty.
- The same under-16 helmet rule applies to e-scooters; for adults a helmet is not required but strongly recommended.
🔓 Exceptions
- A child with a medical certificate exempting them from the helmet on health grounds is outside the duty.
- For adults (16 and over) a bike helmet is not required by law, though it is strongly recommended for safety.
- Although the helmet is mandatory only under 16, a general duty of care remains, and guardians are responsible for the child's safety in traffic.
⚠️ Penalties & fines
The helmet duty is a safety rule, not a revenue stream, and the emphasis is on education rather than punishment. The law tasks police and guardians with drawing children's attention to the duty, and in practice it is enforced through reminders and warnings rather than heavy fines on children. The most serious cost is not legal but physical: head injuries are among the most dangerous outcomes of cycling accidents and a helmet cuts them sharply, so what is really at stake is the child's health. The hidden cost also shows up in compensation and insurance: if a child was not wearing the mandatory helmet, it can affect the assessment of contributory fault in an accident, and therefore the payout. For parents the duty is a reminder that they are responsible for the child's safety gear, and the example matters — a child who grows up wearing a helmet keeps the habit. On an e-scooter the same under-16 rule applies, so the limit follows the child from one vehicle to the next.

❓ Frequently asked
Is the helmet duty at 15 or 16?
It applies to children under 16 under article 79 of the current Traffic Act, not 15 as older sources often say. The limit was raised from 15 to 16 and moved into statute when the new Traffic Act took effect on 1 January 2020, so the "under 15" figure is out of date.
Do adults have to wear a bike helmet?
No, for those 16 and over a bike helmet is not required by law in Iceland but is optional. It is strongly recommended for safety, since it sharply reduces the risk of serious head injuries in an accident.
Is there any exemption from the helmet duty?
Yes, a child who has a medical certificate exempting them from wearing a helmet on health or medical grounds is not bound by the duty. Otherwise it applies to all children under 16 when cycling, regardless of the distance or place.
Does the helmet duty also apply on an e-scooter?
Yes, the same rule applies to small electric vehicles like e-scooters: a rider under 16 must always wear a helmet. The limit therefore follows the child from one vehicle to the next, and for older riders a helmet is recommended but not required on either a bicycle or an e-scooter.
What happens if a child cycles without a helmet?
The emphasis is on education and reminders rather than heavy fines, and police and guardians are to draw children's attention to the duty. The more serious consequence is that a missing mandatory helmet can affect the assessment of contributory fault, and therefore the payout, if an accident happens.
