Why do I need to use a three-point occupant restraint if my childs wheelchair has its own seatbelts?
The seatbelts and other positioning devices that may be used on your wheelchair during non-transit use are not the same as the occupant restraints used to keep your child secure in the event of a motor vehicle accident. The bus or van driver must employ the 3-point occupant restraint system, which secures the occupant in the wheelchair, in order for your child to be safe. Wheelchair positioning belts and devices will not protect your child in the event of a motor vehicle accident.
