Keeping children with additional needs safe while travelling: harness and seating options

Children with additional needs, including autism, ADHD, learning disabilities or behavioural conditions, may sometimes unbuckle or climb out of their car seat while a vehicle is moving. This presents significant safety risks for both the child and other vehicle occupants.

Several specialist harnesses and buckle guards are available, but it is important that any solution is appropriate for the child’s needs and is used in line with manufacturer guidance and road safety regulations.

Important First Steps
Before considering specialist equipment:
• Check whether the child has outgrown their current seat or harness.
• Ensure the seat is correctly fitted.
• Consider behavioural strategies or visual supports.
• Consider mainstream solutions, such as the 5-point plus or additional chest clips for 5-point harness car seats.
• Seek professional advice from an Occupational Therapist, specialist car seat advisor or mobility centre.

Specialist Harnesses and Restraints
Specialist Harnesses and Car Seats are available from several specialist companies including:
• Crelling
• Windmill Special Needs
• Tendercare
• In Car Safety Centre
• Smirthwaite
• Schuchman’s

Assessment is essential
A child repeatedly leaving their seat while travelling may require a holistic assessment considering:
• Medical conditions
• Sensory needs
• Behavioural triggers
• Postural support requirements
• Family transport arrangements

A specialist assessment can identify safe and appropriate solutions while ensuring compliance with road safety regulations.

Parents and carers should avoid modifying standard car seats or using untested products, as this may compromise safety in a collision.

The most suitable option will depend on the child’s age, size, diagnosis, behaviour and transport needs, so individual assessment is strongly recommended before purchasing specialist equipment.
