Until what age is a car seat mandatory in Ukraine?

Until 12 years and at the same time until 150 cm in height. A child is exempt from a seat only when both conditions are met — age 12+ OR height 150 cm+ depending on the inspector's interpretation; it is safer to go by height.

Can I carry a child on a booster instead of a seat?

Yes, if the child fits a booster by height and weight (usually from 22 kg and up). A booster raises the child so the car's belt sits correctly — it is a legal restraint system for older children under 150 cm.

What is the fine for not having a car seat?

An administrative fine is imposed under Article 121 of the Code of Administrative Offences; a repeat breach within a year is punished more severely. Verify the exact amount against the current wording of the Code, as it is revised periodically.

Rules for Carrying Children in Cars 2026 (150 cm rule)

What the law says in 2026

Carrying children in Ukraine is governed by clause 21.11 of the Road Traffic Rules. The rule is unambiguous: a child under 150 cm tall and under 12 years old may only be carried using a child car seat (a restraint system) matched to the child's weight and height. This is not a recommendation but a requirement, and breaching it carries a fine. Note that two conditions work together — both age and height. So even if a child is under 12 but already taller than 150 cm, a seat is formally not required; and vice versa.

The 150 cm rule in plain terms

Why 150 cm exactly? The car's own seat belt is designed for an adult. On a shorter child the lap part lies across the stomach rather than the hips, and the diagonal part across the neck. In a crash this leads to severe internal injuries. Until the child reaches 150 cm, they need to be "raised" with a seat or a booster so the belt runs correctly — across the shoulder and pelvic bones. So focus on height first, not on the child's wish to sit "like an adult".

Until what age a car seat is mandatory

Formally — until 12 years OR until reaching 150 cm in height (both conditions are needed to be exempt from a seat). In practice most children reach 150 cm closer to 11–13 years, so a seat or booster accompanies the child through almost all of the early school years. Do not rush to remove the restraint early: statistically it is the "transition" age of 7–11, when parents abandon the booster too soon, that produces a spike in injuries.

Fines for breaches

Carrying a child without a car seat in breach of clause 21.11 attracts an administrative fine under Article 121 of the Code of Administrative Offences. A repeat breach within a year carries heavier liability. Always check the exact amount against the current wording of the Code, as fine levels are revised periodically. But the real "price" of a breach is not money — it is the risk to the child.

Exceptions

Emergency-service vehicles and certain operational transport.
Scheduled public transport (buses, minibuses) — the requirement for a separate seat does not apply as it does to passenger cars.
Taxis — interpretations vary; it is safer to always have your own seat or booster, especially for small children.

The exceptions relate to the type of transport rather than to "convenience". In your own passenger car, a seat is always required.

How to choose the right restraint system

To stay within the rule and actually protect your child, the system must match their measurements. An infant needs a carrier, a preschooler a seat with an integrated harness, and a school-age child under 150 cm a Group 2/3 seat or a high-back booster.

For children approaching 150 cm, a booster is a convenient solution.

Summary

Remember the 2026 formula: under 12 and under 150 cm — a seat is mandatory. Focus on height, do not remove the booster early, and choose the system by your child's actual measurements — that way the law is met and the child is safe.
