Not every accessible bay has a post in front of it. Where the space sits against a wall, a column face, a fence rail or a horizontal bracket, this is the plate that fits: DISABLED PARKING on a 300mm x 225mm landscape face, $10.45, SKU UNI_TRA_047. It is the landscape plate in the car park range, and the portrait version, UNI_TRA_041, is the one for posts and bollards.
How many accessible spaces a building needs, and how they must be signed, depends on its class and use. That is settled in the access consultant's schedule and the car park design documentation, not on a product page. Read this plate as bay identification supporting the accessible parking signage specified for the site. It identifies the bay by legend, so check the schedule for any additional symbol signage it calls for.
Practically, fix it square to the approach and high enough that a parked van does not swallow it, and keep the mounting height the same across every bay so the car park reads consistently. Material is mostly a weather question: aluminium 1.6mm outdoors on an exposed fence line, white composite (ACM) or polypropylene under cover.
