UK Car Seat Laws: The Basics

By law, child passengers must use a child car seat until they are either 12 years old or 135cm tall, whichever comes first. After reaching this threshold, they must always wear a seat belt. Ensuring you adhere to car seat laws not only protects your child, but also helps you avoid fines.

Choosing the Right Car Seat

Height-Based Car Seats (i-Size)

Height-based seats are designed to provide enhanced safety, keeping children rear-facing until at least 15 months old. This positioning offers superior protection for a child’s head and neck during a collision.

Weight-Based Car Seats

Weight-based car seats fall into the following categories:

• Group 0: For babies up to 10kg (birth to 6–9 months).
• Group 0+: For babies up to 13kg (birth to 12–15 months).
• Group 1: For children weighing 9–18kg (9 months to 4 years).
• Group 2/3: For children weighing 15–36kg (4 to 12 years).

When selecting a seat, ensure it fits both your child and your vehicle. Always look for the EU-approved label, featuring a capital 'E' in a circle and ‘ECE R44’. Discover our blog on buying the right car seat.

Understanding Booster Seat Regulations

Since March 2017, backless booster seats are approved only for children over 22kg and taller than 125cm. High-back booster seats are recommended for better safety, offering superior head and side protection during side-impact collisions.

Exceptions to the Rule

Although it’s always safest to use an appropriate child car seat, there are a few exceptions:

• Taxis and Minicabs: If a child seat isn't available, children over 3 years old must use an adult seat belt. Under 3s can travel without a seat belt.
• Coaches and Minibuses: When child seats or seat belts aren’t fitted, children over 3 must use an adult seat belt if available; under 3s can travel without a seat belt.
• Unexpected Journeys: On short, necessary trips, a child over 3 may use an adult seat belt if no child seat is available.

For convenience, AMT Auto offers a range of child car seats that can be added to any vehicle rental booking.

Consequences of Non-Compliance

Failing to properly restrain child passengers carries a fine of up to £500 and significantly increases the risk of injury or fatality in an accident. By ensuring your child is properly secured, you prioritise their safety and well-being.
