front correct restraint must be used
rear Where seat belts fitted, correct child restraint MUST be used. Must use adult belt if the correct child restraint is not available:
- in a licensed taxi/private hire vehicle; or
- for a short distance for reason of unexpected necessity; or
- two occupied child restraints prevent fitment of a third.
A child 3 and over may travel unrestrained in the rear seat of a vehicle if seat belts are not available.

3. What do you mean by "child restraints"? And what about seat belt adjusters?
"Child restraints" is the collective term in the seat belt wearing legislation for baby seats, child seats, booster seats and booster cushions.
Modern child restraints are designed for specific weight ranges of child. They have to meet UN ECE Regulation 44.03 (or subsequent) type approval standard and be marked with a label (showing an "E" and "44.03" or ".03") and the Group number, or weight range of child, for which it is designed. All child restraints that meet the Regulation 44.03 type approval standard are approved for use in forward-facing or rear-facing seats.
Manufacturers use different names for their products so the names we have used below may not always apply and are a guide only. Manufacturers sometimes combine weight ranges in one product so that it can be used over a longer time as a child grows. It is the weight of the child that decides the restraint that must be used.
Group 0 and Group 0+. These are baby seats - rear-facing and for children up to 10kg and up to 13kg respectively (approx age birth to 9-12 months);
Group I. Child seats - forward facing and for children 9kg to 18kg (approx 9 months to 4 years);
Group II. Booster seats - for children from 15kg to 25kg (approx 4 to 6 years), or 15kg up to 36 kg);
Group III. Booster cushions - for children from 22kg and up to 36kg (from approx 6 years).
Seat belt adjusters are comfort devices and not safety devices (check what the manufacturer says about them and their intended use). Only if an adjuster is labelled that it has been approved (and therefore tested) to the UN ECE Regulation 44.03 type-approval standard can it used instead of a type-approved child seat/booster.
