New child car seat law in Spain: Everything expats need to know in 2025

Ensuring your child’s safety while driving is essential, especially when living abroad. If you’re an expat in Spain, it’s crucial to stay informed about the latest child car seat regulations. In 2024, Spain’s General Directorate of Traffic (DGT) introduced new rules aligned with European safety standards to enhance child passenger protection. Here’s everything you need to know to comply with the law and keep your little ones safe.

What are the new child car seat regulations for 2025?

From September 2024, all children under 135 cm in height must travel in an approved child restraint system (CRS). The key update is that car seats must now comply with the R129 regulation (i-Size), which simplifies selection by using height instead of weight, ensuring a better fit and enhanced safety as children grow.

Key changes in the new child car seat regulations

• R44 car seats can still be used, but new models will no longer be sold after September 2024. The DGT will only allow the sale of R129-certified seats, which provide enhanced protection.
• Children under 15 months must travel in a rear-facing car seat whenever possible, as this significantly reduces injury risks in the event of a crash.

Child car seat height and age requirements

• Children under 135 cm must use an R129-compliant CRS.
• Experts recommend using a CRS until children reach 150 cm for maximum safety.
• While the law sets minimum requirements, following expert guidelines ensures the safest travel.

How to choose a compliant child car seat in 2025

• When selecting a child car seat, ensure it: 
  Is certified under Regulation R129 (look for the i-Size label).
• Is compatible with your car’s ISOFIX system (standard in most cars since 2013).
• Matches your child’s height and weight requirements.
• Allows rear-facing travel for as long as possible, especially for children under 15 months.

R44 vs R129 (i-Size): What’s the difference?

The main difference is that R44/04 classifies car seats by weight, whereas R129 (i-Size) uses height. R129 also introduces side-impact testing and encourages ISOFIX installation for improved safety.
 

Six key advantages of R129 over R44:

1. Rear-facing car seats are mandatory until at least 15 months.
2. Side-impact testing is now required for all seats.
3. Car seats are classified by height, making it easier to choose the right one.
4. Advanced crash test dummies (Q series) are used, providing more accurate safety data.
5. Better compatibility with vehicles, ensuring seats fit most modern cars.
6. ISOFIX is preferred, reducing the risk of incorrect installation.

Frequently Asked Questions

Is it mandatory to install child car seats in a rear-facing position?
Yes, for children under 15 months or shorter than 71 cm, rear-facing installation is required. Experts recommend keeping children rear-facing for as long as possible, as it offers superior protection.

Which vehicles must comply with the new child car seat regulations?
All passenger vehicles—including cars, vans, and similar transport—must follow these regulations to ensure young passengers’ safety.

What if I already have a child car seat?
If you already have an R44/04-certified car seat, you can continue using it for up to eight years. However, any new seat purchases must comply with R129. Upgrading to an R129 seat is recommended for better protection. 
Failing to comply with these regulations can result in a €200 fine and a loss of three points on your driving licence. If authorities find a child travelling without the correct CRS, they may immobilise the vehicle until the situation is rectified.
