TS ISO 2575/Amd 7

TS ISO 2575/Amd 7 is Amendment 7 to the TS ISO 2575 series for symbols used on road vehicles for controls, indicators and tell-tales. In technical terms, this subject covers the visual language used on vehicle interfaces so that functions can be recognized quickly without relying on text. It supports the identification of switches, indicator lamps, dashboard symbols and tell-tale signals that communicate status, warnings or operating conditions. As an amendment, this record should be understood as a change to the parent standard rather than a stand-alone full specification.

Why vehicle symbols matter

In road vehicles, standardized symbols help reduce language dependence and improve consistency across markets. A control symbol identifies the function of a control; an indicator shows system state; and a tell-tale is the visual signal that a condition is active or needs attention. From a general engineering perspective, clear symbol design is important because dashboard communication must be fast, legible and resistant to misinterpretation under driving conditions. That is why symbol standards are closely tied to human factors and cockpit ergonomics.
