At what age can children cycle on their own in Denmark?

Under 6 only with an older companion.

Answered at: Checked at:

Short answer

Danish law says a child under 6 may not cycle unless a person who has turned 15 goes along and keeps control of the child. From the age of 6 a child may cycle without a companion, but must follow the same traffic rules as adults. A child under 6 riding alone has a guideline fine of 700 kr. as of 2025, and the fine on a bike usually goes to the rider. A person aged 15 or older can therefore be the companion, so an older sibling may ride along.

Why

  1. Under 6 needs a companion aged 15 or more.
  2. From 6 a child may ride alone.
  3. Children follow the same rules as adults.

Details

To carry a child on a bike or in a bike trailer, the rider must also be at least 15.

Tip

Let young children practise in parks or quiet streets before they ride on busy cycle paths.

What may differ

If there is an accident or a dangerous situation, the guideline fine does not apply and it can be higher.

Common misconception

Any companion will do, even a young sibling.

What actually happens

The companion of a child under 6 must be at least 15 years old.
