Half of Spanish children travel unsafely in cars due to improper restraint use

Every spring, as families pack their cars for Easter week and the highways fill with weekend travelers, Spain's traffic authorities see the same pattern repeat: children strapped into seats that are installed wrong, adjusted wrong, or used in ways that strip away their protection without anyone quite realizing it. This year, the numbers have gotten worse. More than half of Spanish families—54 percent—are using child safety systems incorrectly in their vehicles, according to data from Cybex, a company that specializes in child transportation safety. The European Commission confirms the scale of the problem: more than half of all children in Europe travel without proper safety conditions. But what makes this year different is not just the prevalence of the mistake. It is that the mistake is growing.

Traffic police are catching more families in violation each year. The Spanish traffic authority, the Dirección General de Tráfico, recorded 458 minors traveling without proper restraints or with improper use in 2026. That is up from 385 cases in 2025 and 317 in 2024. The increase tracks partly with more intensive enforcement campaigns, but also with the simple fact that more families are on the road during peak travel periods. Semana Santa—Holy Week—is one of the busiest times on Spanish highways, which means more children are exposed to risk, and more violations go undetected.

The errors themselves are not mysterious. They are the small, daily mistakes that parents make because they do not know better, or because they are rushing, or because the correct way feels inconvenient. Harnesses left too loose. Children dressed in heavy winter coats that prevent the straps from fitting snugly against their bodies. Headrests not adjusted to match a child's height. ISOFIX anchor systems installed incorrectly. Parents moving children to forward-facing seats before they are old enough, thinking their child is ready when the rules say otherwise. Some families reuse secondhand car seats without knowing whether they have been in accidents or damaged. Others never check whether the installation remains correct as their child grows.

Spain's law is clear: any child under 135 centimeters in height must travel in a child restraint system appropriate to their size and weight. Since September 2024, only devices certified under the new European standard ECE R129 can be sold. This standard is stricter than what came before. It requires children to travel rear-facing until at least 15 months old. It includes lateral impact testing. It classifies seats by the child's height rather than age alone. These rules exist because they save lives. But a rule on paper means nothing if the person installing the seat does not understand it, or if the parent using it every day does not follow it.

Experts emphasize that a certified car seat is only part of the equation. How families travel matters too. Planning routes to avoid fatigue, stopping regularly, keeping the car at a comfortable temperature, removing loose objects that could become projectiles in a sudden stop—these are simple practices that reduce risk. During high-traffic periods like holidays, when families are tired and eager to reach their destination, these details become even more critical. A properly installed and correctly used car seat can mean the difference between a child walking away from a crash and a child in a hospital bed. The technology exists. The regulations exist. What is missing, in more than half of Spanish families, is the knowledge or the discipline to use them right.
