Are you planning to travel with children in your car? Remember, in the UK all children under the age of 12 years must be in a child restraint unless they are taller than 135cm (or taller than 150cm in some other European countries).
Take a few extra minutes to check that their child restraint is adjusted correctly to their size.
Remember to pull harnesses nice and snug (refresh your knowledge from the instruction leaflet provided with the car seat).
