Rules checked against official guidance on 15 October 2026.
In a passenger car, a child under 150 cm tall must use an appropriate child restraint. Turning 12 does not, by itself, remove the requirement to use a car seat or booster. The fine for breaching child passenger rules is UAH 510, rising to UAH 850 for a repeat violation within one year. Guidance from Ukraine’s Patrol Police.
This guide covers journeys in passenger cars, including rental cars. Organised bus transport and special-purpose vehicles are subject to separate provisions.
When does a child need a car seat or booster?
Rule 21.11 of Ukraine’s Road Traffic Rules uses height as the key threshold: a child needs a child restraint until they reach 150 cm. The restraint must suit the child’s height and weight, and it must be installed according to the car seat and vehicle manufacturers’ instructions. The child must be properly secured in it. Rules 21.11–21.16 are reproduced in official guidance from the Main Service Centre of Ukraine’s Ministry of Internal Affairs.
Age alone is therefore not enough. For example, a 12-year-old who is 145 cm tall still needs an appropriate restraint. At 150 cm or taller, a special restraint is no longer compulsory under this height-based provision, but wearing the vehicle’s seat belt remains mandatory.
A booster is not suitable for every child. Check its manufacturer’s permitted size limits and ensure the seat belt fits correctly. An ordinary cushion is not a substitute for an approved child restraint.
When can a child travel in the front seat?
There is no general permission that starts automatically at age 12. You must consider the child’s height and the restrictions on installing a child restraint in the front row.
Under rule 21.13, child restraints must normally be installed outside the front row. There is an exception for a child under three years old: in a passenger car, a rear-facing restraint may be installed in the front row if the frontal airbag for that seat, where fitted, is switched off. The installation must also be permitted by both the restraint and vehicle instructions.
| Situation | Required arrangement |
|---|---|
| Child under 3 years old and under 150 cm tall | An appropriate restraint outside the front row; front-row installation only under the rear-facing exception, with the frontal airbag switched off |
| Child aged 3 or older and under 150 cm tall | An appropriate child restraint outside the front row |
| Child 150 cm tall or taller | The vehicle’s seat belt; these provisions do not impose a separate front-row ban solely because the child is under 12 |
Legal permission and safety advice are different. NHTSA, the US National Highway Traffic Safety Administration, recommends that children under 13 travel in the back seat. This is safety advice, not an age threshold in Ukrainian law. Never place a rear-facing restraint in front of an active frontal airbag. NHTSA airbag guidance.
Do not automatically switch off the airbag for every child passenger. For other permitted seating arrangements, follow the specific vehicle’s owner’s manual.
How to choose a child car seat
Start with the child’s current height and weight, then check the chosen seat’s limits and compatibility with the vehicle.
- For an infant, choose an infant carrier or car seat designed for rear-facing travel. Follow the manufacturer’s instructions for the recline angle and installation.
- For an older child, keep the seat rear-facing for as long as its height and weight limits allow. When moving to a forward-facing seat, use the harness and attachments specified by the manufacturer.
- When moving to a booster, check the permitted child size and the fit of the vehicle’s seat belt. The lap belt should sit low across the upper thighs; the shoulder belt should cross the shoulder and chest, not the neck.
These recommendations on selecting and changing seats come from NHTSA. In Ukraine, you must also comply with the compulsory 150 cm threshold.
ISOFIX is a way of attaching a car seat to the vehicle. It does not replace the seat itself, its harness or the vehicle’s seat belt where required by the installation instructions. Use only the combination of attachments approved by the manufacturers.
What to check before setting off
Check the seating arrangement before all passengers get into the car:
- The seat’s label confirms it is suitable for the child’s size.
- The seating position and installation method are permitted by the instructions.
- All required attachments are in place and the belts are not twisted.
- The child is secured and the harness or belt is adjusted as instructed.
- Bulky winter clothing does not prevent the harness from fitting closely.
- For permitted rear-facing front-row installation, the frontal airbag is switched off.
Ukraine’s Ministry of Internal Affairs also advises removing bulky outer clothing and adjusting the belts correctly. Official safety guidance. Check the restraint before every journey, including short trips.
What is the fine for travelling without a child car seat?
Liability is set out in parts 10 and 11 of article 121 of Ukraine’s Code of Administrative Offences:
| Violation | Fine |
|---|---|
| Breach of child passenger transport rules | UAH 510 |
| Repeat violation within one year | UAH 850 |
The amounts and legal basis are confirmed by Ukraine’s Patrol Police. The offence concerns compliance with the transport rules, so merely carrying a seat in the car is not enough: it must be used correctly.
Travelling with a child in a rental car
Arrange the child equipment before collecting the vehicle. Tell the rental team each child’s height and weight and how many children are travelling. Confirm the seat model, installation method, vehicle compatibility and availability of instructions.
The BLS additional services page lists child equipment. Check the availability of a suitable model and the terms for your specific booking. At collection, make sure you receive the agreed seat and can secure it correctly in a permitted position.
Do not rely on an approximate age category alone: children of the same age can differ considerably in height and weight.
Frequently asked questions
Can a 12-year-old travel without a child car seat?
If the child is under 150 cm tall, an appropriate child restraint is still required. Turning 12 does not remove that requirement.
Can a child use a booster in the front seat?
Not if the child is aged three or older and under 150 cm tall: the restraint must be installed outside the front row. The front-row exception concerns children under three in a rear-facing restraint with the frontal airbag switched off.
Can an adult hold a baby during the journey?
No. An adult’s arms do not replace an appropriate child restraint. The police specifically remind drivers that this arrangement can result in a penalty.
Can a car seat be used without ISOFIX?
Yes, if the seat manufacturer and the vehicle instructions permit installation using the vehicle’s seat belt. Follow the installation method specified for that model.
Must the airbag be switched off for a child who is 150 cm or taller?
There is no general rule requiring the airbag to be switched off for every child. Mandatory deactivation applies to the rear-facing front-row exception described above. In other cases, follow the vehicle’s manual; NHTSA recommends the back seat for children under 13.
