One of the new measures proposed (although not yet approved within the corresponding law), is that children under 135cms in height cannot travel in the front seat if there are other seats free.
Child car seats: rules for installation and use
Within the new regulations there is an obligation that, if the seat allows, children up to 18 kilos (about 4 years old) should travel in a backward facing direction.
During their first years of life, 25% of a child’s total weight is the head but the ligaments and muscles are not fully formed until they are older.
As far as the DGT is concerned, they only oblige you to install car seats from group 0 and 0+ in a backward facing direction. If the new law is approved, it will also include those in group I so long as the seat allows it.
If the seat that we are already using is from group I and it cannot be installed backward facing (although obliged by law) there is no need to buy a new one and you can carry on using it. This exception is due to the fact that most seats purchased in Spain up to now cannot be installed backward facing.
What this new regulation aims to do is educate people to the fact that a backward facing seat is much safer for small babies.
Child car seats - safety tips
What you must keep in mind for the safety of children and babies travelling by car, is the correct installation of the seat either backward facing or not.
We must ensure that the seatbelt is always fastened and cannot easily come undone and although it seems obvious, we must never take the child out of the seat and leave them un restrained even on a short trip.
Finally, don’t let us forget that if a child is under 135cms in height they must not be seated in the front passenger seat using the seatbelt, unless they are using a suitable child seat (for their weight, and height).
Once they are above this height they can then sit in any of the seats in the car using a seatbelt.
