Rules for using a child car seat or booster seats. UK child car seat law regulates the correct use of restraints for small children in vehicles.
CHILD SEATS LAW: As a rule, children must use a suitable child car seat until they either:
UK law requires children to wear a seat belt after they are 12 or taller than 135cm. But, until one of those occur, the choice of child car seat gets based on their height or weight.
Several other factors govern baby car seat laws. They include the type of vehicle used and whether it functions as a minibus or a licensed taxi.
A child's weight often determines the best type of car seat or child restraint to use. RoSPA research shows young children are more vulnerable in vehicle collisions than adults.
Note: Not using the correct device, and not wearing a seat belt, can cause severe injuries and death.
Child restraints refer to specific car seats regulations for children under 12 years old. They include rear facing baby seats, forward facing chairs, and booster seat cushions.
|Child Weight||Group||Type and Facing Position of Child Car Seat|
|Infants up to 10kg||0||Use a 'lie-flat or lateral' baby carrier, rear-facing baby carrier, or a rear-facing baby seat with harness|
|Babies up to 13kg||0+||Use a rear-facing baby carrier or rear-facing baby seat with harness|
|Toddlers from 9kg to 18kg||1||Use a rear or forward facing baby seat with a harness or safety shield|
|Children from 15kg to 25kg||2||Use a rear or forward facing child seat (high-backed booster or booster cushion) with a seat belt, harness or safety shield|
|Children from 22kg to 36kg||3||Use a rear or forward facing child seat (high-backed booster or booster cushion) with a seat belt, harness or safety shield|
Manufacturers must now make booster cushions approved as group 3 only. But, you can still use booster cushion types in group 2.
Height-based 'i-Size' car seats must be rear-facing until your child turns 15 months old. Afterwards, your child can use a forward-facing car seat. You must check the seating installation and ensure it is suitable for your child's height.
Note: The UK only allows the use of EU-approved height-based child car seats. This type has a label showing a capital 'E' in a circle with 'R129'.
Child weight influences the car seat you should use and the method that is restrains them. So there are several different child car seat manufacturers to choose from.
Note: The UK only allows the use of EU-approved weight-based child car seats. This type has a label showing a capital 'E' in a circle with 'ECE R44'.
Your car must have a seat belt with a diagonal strap to install and use a child restraint. Exceptions apply if the car seat is either:
By law you must also:
The same car seat rules apply for children with a disability or a medical condition. But, you can fit a disabled child car seat or they can use a seat belt for restraint. Your doctor may provide an exemption certificate if your child is unable to use standard vehicle seating restraints.
You can choose your child car seating based on the height or weight of the toddler. But, there are two different European standards for using child restraint systems.
The two car seat standards are Regulation 129 (i-Size or ISOFIX seats) and Regulation 44.
Regulation 44 child seats base their use by child weight with a recommendation on age. Whereas, child height is the main criteria for Regulation 129 child seats law.
The EU safety regulation for child car seats (ECE R129) developed the rating of 'i-Size' in July 2013. The aim was to make them easier to install and increase protection from side impacts. The design focused on keeping children rearward-facing until they grew taller and heavier.
Most new i-Size seats 'click' easily into place using vehicle anchorage points. There is no need to use an adult seat belt for securing i-Size car seats into place. But, you should make sure your car has ISOFIX anchorage points fitted to use this model correctly.
Child car seats are safe and legal no matter which EU manufacturing standard they follow. Use this guide to find out if your child or baby car seat should be a forward-facing or rear-facing device.
There are several occasions when a child does not need to use a car seat while travelling in a vehicle. This list explains the legal exceptions to the standard vehicle safety rules and restrictions.
What happens if a licenced taxi or minibus driver does not provide the correct car seat? In these cases children can travel without using one providing they travel on a rear seat. The child must sit behind the driver and:
By law minibus or coach companies, and their drivers, do not need to provide child car seats. So you must provide your own if you consider it important for your child to use one.
Coaches: Children can travel in a coach without using car seating or safety belt if neither are available.
Minibuses: All children must travel in the rear compartment of a minibus. They can use any seating space behind the driver. This applies even if no seat belt or child booster seat got fitted. But, children aged 3 or older must:
Vans: The UK child seat law is the same for vans as it is for cars.
Children over 3 can use an adult car belt if the correct seating is unavailable and all the journey is:
To take children under 3 on an unexpected journey in a vehicle without the right seating can only happen if:
Under UK law all children under 3 must be properly secured in a child car seat. What happens if there is no room for a third child seat in the back of the vehicle?
In this case children under three must travel in the front seat with the correct child seat. Children over three years can sit in the back using an adult belt.
Children under 3 must travel in a child car seat. If there is no seat belt, they cannot travel in that vehicle. Children over 3 can travel in the back seat without a car seat and without a seat belt if the vehicle does not have one.
Seek professional advice for help choosing the right car seat. Travel safely with children in your vehicle.
