Car seat regulations in Spain
*Children under 12 years and under 135cms should not travel in the front seat without a car seat specific for this purpose.
Children under 12 years and under 135cms should be placed in the rear seats of a vehicle in car seats appropriate to their weight and height.
Children may travel in taxis unrestrained, but not in the front seat (some local specifications may apply).
*source: Campaign for the use of child restraint systems: www.tenecesitanprotegeles.com, March 2010. On the campaign's webpage there is a box on the left hand side where you can type in the height and weight of your child. Press search (buscar) and then hover over the seat types and the one considered suitable for your child is shown in colour.
See the information on airlines to find out if you can take a car seat on board the aeroplane.
