TS ISO 2575/AMD 1:2011

TS ISO 2575/AMD 1:2011 is Amendment 1 to ISO 2575 for road vehicles, covering symbols used for controls, indicators and tell-tales. In vehicle interiors, these symbols provide a fast, language-independent way to recognise switches, controls and warning or status indicators, so the meaning of each graphic sign matters for safe and consistent use.

In general technical terms, this subject is about creating a shared visual language across vehicle brands and markets. Controls are the actuating elements the driver uses to command a function, indicators present information about vehicle state, and tell-tales are symbolic signals that show a specific condition or alert is active. Distinguishing these categories helps users interpret a symbol correctly as an action, a status display or a warning cue.

Why symbol standardisation matters in vehicles

Vehicle symbols reduce reliance on text labels and improve recognition in compact cockpit spaces. Well-designed pictograms support quick comprehension through simple shapes, clear contrast and consistent visual logic. In practice, this makes control and warning graphics an essential part of automotive human-machine interface design.
