How to Transport an Autistic Child by Car

Transporting an autistic child by car may require specific preparation. Some children travel easily, while others may find it difficult to tolerate engine noise, vibrations, the feel of the seat belt, changes to the route, or being unable to move freely. These difficulties can lead to stress, agitation, or attempts to unfasten the restraint. Every child has their own sensory profile, communication methods, and routines. There is therefore no single solution suitable for every situation. The aim is to make the journey as predictable as possible, comply with road safety regulations, and, where necessary, use suitable additional equipment, such as an in-car harness for autistic children. Identifying Difficulties Before the Journey Autistic children may be sensitive to sounds, smells, lights, textures, or movement. The unpredictability of traffic congestion, a change of route, or an unexpected stop may also cause anxiety. However, needs and reactions vary considerably from one child to another.

Before choosing any equipment, it is important to identify what is actually causing the child discomfort.

Is it the feel of the seat belt, sunlight, noise, heat, or the length of the journey? Are they trying to unfasten themselves because they are uncomfortable, because they do not understand what is going to happen, or because they need to move? Identifying the cause of the behaviour makes it possible to provide more appropriate support. A sensory difficulty will not necessarily require the same response as a problem related to understanding, posture, or repeated attempts to unfasten the seat belt. Preparing an Autistic Child for Car Travel Good preparation can help make the journey more reassuring. The trip can be explained using simple words, pictograms, or a short visual sequence: get into the car, sit down, fasten the restraint, travel, arrive, and get out. For an unfamiliar journey, a few short practice trips may help the child gradually become accustomed to the vehicle. Routines, simple information, and visual cues can help some autistic children understand the different stages of an activity. It may also be helpful to maintain familiar reference points, such as using the same seat in the car, travelling with a familiar adult, keeping predictable schedules, and bringing a familiar object. Depending on the child’s needs, noise-reducing headphones, familiar music, a sensory toy, or a sunshade may improve comfort. Instructions should remain short and specific, for example: “Stay seated” or “The seat belt stays fastened.” Long explanations are best avoided when the child is already stressed. For longer journeys, schedule regular breaks in safe locations. However, any comfort item must be compatible with the child’s correct positioning and must never interfere with the seat belt, child car seat, or any additional restraint equipment. The Seat Belt and Child Car Seat Remain Mandatory In France, the driver must ensure that a child under the age of ten is secured in an approved restraint system suited to the child’s size and weight. The child car seat or booster seat must be used in accordance with the manufacturer’s instructions. Our disability car support vest or postural support harness does not replace the legally required child car seat, booster seat, or vehicle seat belt. The seat belt must remain fastened while the support harness is being used. The harness must be regarded as an additional piece of equipment designed to meet a postural need or reduce attempts to unfasten restraints during the journey. Before use, the product’s compatibility with the child’s height and body shape, the vehicle seat, and the vehicle itself must be checked. When in doubt, advice should be sought from an occupational therapist, doctor, disability specialist, or specialist vehicle equipment installer. When Should a Support Harness Be Used? Some children repeatedly remove their seat belt, slide down in the seat, lean significantly to one side, or attempt to leave their seat while the vehicle is moving. These behaviours may place the child at risk and distract the driver. A disability transport harness may therefore be considered to improve support in the seated position and provide additional assistance during the journey.

The Access-Ability support harness is designed for children and adults with behavioural conditions, muscular difficulties, or a need for additional trunk support. It helps maintain posture while the person is seated in the vehicle’s original seat. Made in France from neoprene fabric, it includes: a support base fitted around the vehicle seat;an adjustable back panel;a front panel fitted with seven lockable buckles;keys used to open the buckles;an emergency seat-belt cutter and window hammer.According to Access-Ability, the standard model is suitable for people measuring between 1.10 m and 1.75 m. The manufacturer also states that it can be installed on various types of seats, including those in private cars, taxis, buses, minibuses, and wheelchair-accessible vehicles. For children, it may be used with a booster seat, always in addition to the vehicle’s seat belt. This type of harness should only be used to address a genuine safety or postural need. It must be correctly adjusted, checked regularly, and used in accordance with the manufacturer’s instructions. Everyone who may transport the child must also understand how it works. Why Add an Escape Box? In an emergency, the child must be able to be removed from the vehicle quickly. This is particularly important when the harness includes several lockable buckles. The Access-Ability harness has a standard release system located behind the seat. Two red buttons allow the harness to be released quickly when the back of the seat is easily accessible. When access to the back of the seat is difficult, the optional Escape Box allows the emergency release system to be operated from the front, at the top of the seat. According to Access-Ability, this avoids having to open all seven buckles individually and makes it easier to remove the child quickly in a critical situation. The Escape Box is designed exclusively for use with the brand’s support harness. The package supplied with the Escape Box includes the support base, the seven-buckle front panel, the keys, the emergency seat-belt cutter and window hammer, and the evacuation system. Access-Ability describes the complete system as CE-certified and classified as a Class I medical device. The keys, evacuation control, and seat-belt cutter must remain easily accessible. Every accompanying adult must know where they are located and how to use them. It is advisable to practise the evacuation procedure while the vehicle is stationary and without the child present, so that everyone can act quickly in an emergency. Checks Before Every Journey Before setting off, check the installation of the child car seat or booster seat, the routing of the vehicle seat belt, and the adjustment of the harness. No strap should be twisted, excessively loose, or positioned against the child’s neck. The child’s breathing must never be restricted, and their posture should remain as natural as possible. Also check that all buckles are properly secured and that the emergency release system remains accessible. The driver must not attempt to adjust the equipment or physically calm the child while driving. In the event of a problem, the vehicle should be stopped in a safe place. For more complex journeys, having a second adult present may make it easier to support the child while allowing the driver to remain focused on the road. A Solution Adapted to Each Child Successfully transporting an autistic child by car relies on several complementary measures: preparing the journey, communicating clearly, taking sensory needs into account, using the legally required restraint system, and, where necessary, adding an appropriate support solution. A support harness and Escape Box may be useful when a child repeatedly unfastens their restraint or requires improved postural support. However, the choice of equipment must be personalised, and its installation must be checked carefully. To identify the most appropriate solution, it is advisable to consult the professionals supporting the child and a specialist in vehicle adaptations. Access-Ability also offers harness trials upon request, allowing its suitability for the vehicle and the user’s needs to be assessed.
