If provided, access aisles for side lift vans must be 96 inches wide to allow full extension of the lift and manuevering space for wheelchair users to approach or leave the lift. In garages, a headroom clearance of at least 114 inches must be provided at van parking spaces and the vehicular route to and from the entrance/exit to the parking space. The extra headroom is necessary to accommodate the raised roofs frequently installed on accessible vans.
