What does 17.5 require?

On all conveyances, premises and infrastructure, words or numbers on a digital information display screen must stay visible for at least 10 seconds, except that a ticket validation screen need only hold them as long as is reasonably necessary to acknowledge the content. On conveyances the screen must be in a direct unobstructed line of sight from priority seating and allocated spaces and visible from other areas with only safety-critical handrails or grabrails in the way; in premises and infrastructure it must be visible from all viewing areas including past its enclosure. It must be readable by a person wearing polarised eyeglasses and meet the contrast minimum in AS EN 301 549 (2020). Letter heights must be no less than Table 2 of AS 1428.2 (1992) gives for the viewing distance, interpreted as capital I heights under AS 1744 (2015), or where the distance is not in the table at least 3.2 mm per metre of viewing distance. Applies to screens installed on or after 13 October 2026.
