Do children have to wear a bike helmet in Denmark?
Not required, but most children wear one.
Short answer
No. There are no helmet rules for children under 15 on a bike or a 25 km/h e-bike in Denmark, just as there are none for adults. Even so, more than 8 in 10 children who cycle to school wear a helmet, and the youngest schoolchildren wear one most often, while children over 12 use it less. A helmet is strongly recommended on every ride. On an electric scooter or a speed pedelec a helmet is required by law at any age.
Why
- No helmet law for children on bikes.
- Over 8 in 10 children wear one to school.
- Teenagers wear helmets less often.
Details
A child under 6 may only cycle on the road with a companion who is at least 15 years old.
Tip
The helmet should sit level and cover the forehead, with room for two fingers under the chin strap; check the straps on your child's helmet once a week.
What may differ
Helmet use differs by age: the youngest schoolchildren wear a helmet most often, and use drops after the age of 12.
Common misconception
Children in Denmark must wear a helmet by law until they turn 15.
What actually happens
There are no helmet rules for children on ordinary bikes; most simply choose to wear one.
