Ensuring all passengers are safely secured is a fundamental legal obligation for every driver in Denmark. In this article, you will learn the specific height requirements for child safety equipment, the legal distinction between adult and child safety duties, and the strict penalties associated with failing to follow these rules according to the Danish Road Traffic Act.

Article content overview
Ensuring the safety of all vehicle occupants is a cornerstone of the Danish Road Traffic Act (Færdselsloven). As a driver, you are legally responsible for ensuring that every passenger is properly secured before the vehicle begins to move. Failure to adhere to these regulations does not only jeopardize the lives of your passengers but also carries significant legal consequences, including heavy fines, penalty points on your license, and potential contributions to the Victims Fund.
According to the Danish Road Traffic Act, it is mandatory for the driver and all passengers to use a seat belt if the vehicle is equipped with one. This rule applies universally, covering cars, vans, trucks, and even buses. The law is explicit regarding capacity: a vehicle must never carry more passengers than there are functional seat belts available. If a seat is fitted with a belt, it must be worn.
The driver is held personally responsible for ensuring that all passengers under 15 years of age are correctly fastened. If a child under 15 is not properly secured, the driver faces a fine of 2,000 DKK, a 500 DKK contribution to the Victims Fund, and a "klip" (penalty point) in their driving license.
When transporting children, the rules become more stringent to account for physical development. Children must be secured using approved safety equipment—such as a child seat or a booster cushion—that matches their height and weight. Specifically, any child under 135 cm in height is required to use an appropriate, approved child restraint system.
It is important to understand that standard seat belts are designed for adults. When a child is under 135 cm, the shoulder belt may cross their neck rather than their shoulder, which can be fatal in the event of a collision. Approved child seats ensure the belt or harness interacts with the child's body in a way that minimizes injury.
Child safety equipment must be approved according to European standards. Currently, you should look for seats labeled with ECE R129 (i-Size) or the older ECE 44-03/44-04 certifications. While ECE 44 models are no longer sold in retail, they remain legal to use if you already possess one.
The Danish regulations distinguish between children based on age and height to ensure the highest standard of protection:
| Child Age/Height | Requirement |
|---|---|
| Under 135 cm | Must use an approved child seat or booster seat |
| 135 cm or taller | May use the vehicle's standard seat belt |
| Under 3 years | Must use child-specific restraint (unless in a taxi) |
In the context of the Danish Category B theory exam, you may encounter questions regarding the chain of responsibility. Remember that while adult passengers are generally responsible for their own seat belts, the driver always retains the legal duty to ensure that children under 15 are secured. If you are stopped by the police and a minor is not wearing a seat belt, the fine and the penalty point are levied against you, the driver.
Furthermore, ensure you are familiar with the concept of "exemptions." While medical exemptions exist, they must be documented by a healthcare professional and approved by the Danish Road Traffic Authority (Færdselsstyrelsen). A simple verbal claim of discomfort is not a legal excuse to forgo seat belt use.
Danish seat belt law requires all occupants to use available belts and mandates approved child restraints for children under 135 cm, with drivers bearing full legal responsibility for passengers under 15. The 135 cm height threshold is critical for determining whether a child seat or standard belt is required, while violations result in a 2,000 DKK fine, a 500 DKK Victims Fund contribution, and one penalty point. Approved child safety equipment must carry ECE R129 (i-Size) or older ECE 44-03/04 certification, and medical exemptions must be formally documented rather than merely claimed. While adults are responsible for their own seat belt compliance, the driver retains responsibility for all minors in the vehicle.
A short set of high-value points that capture the most important ideas from this article.
Drivers are legally responsible for ensuring all passengers under 15 years old are properly secured with seat belts or approved child restraints
Children under 135 cm must use an approved child seat or booster; those 135 cm or taller may use the standard vehicle seat belt
Unsecured children under 15 result in a 2,000 DKK fine, 500 DKK contribution to the Victims Fund, and one penalty point ('klip') for the driver
Approved child seats must carry ECE R129 (i-Size) or ECE 44-03/04 certification labels
Standard adult seat belts are dangerous for children under 135 cm as they can cross the neck instead of the shoulder
The 135 cm height threshold determines when a child can legally use a standard seat belt, while age 15 is the threshold for driver responsibility
The driver holds sole responsibility for passengers under 15; adult passengers are responsible for their own seat belt use
Medical exemptions require documented approval from a healthcare professional and the Danish Road Traffic Authority (Færdselsstyrelsen)
Vehicles may never carry more passengers than there are functional seat belts available
Children under 3 years old must always use child-specific restraints, even in taxis
Confusing the age threshold (15 years) for driver responsibility with the height threshold (135 cm) for child seat requirements
Believing verbal claims of discomfort are sufficient grounds for exemption from seat belt use
Assuming that any adult seat belt is appropriate for a child simply because the child appears large enough
Forgetting that the driver is solely liable even when another adult is present in the vehicle
Overlooking that ECE 44 seats are no longer sold but remain legal if already owned
