About This Item
TS ISO 2575 is the standard for symbols used on road-vehicle controls, indicators and telltales, covering passenger cars as well as light and heavy commercial vehicles and buses. Its core purpose is to make vehicle interfaces easier to recognise and use by giving drivers clear, conventional visual signs.
Why control and telltale symbols matter
In automotive design, symbols act as a language-independent interface. A control symbol helps the driver understand what a switch, knob or control does, while indicators and telltales communicate the state of a system. This is especially important where the driver must interpret information quickly and consistently under real driving conditions.
The standard also indicates the colours of possible optical telltales that inform the driver whether the related device is operating correctly or malfunctioning. In general automotive practice, colour is a key part of visual signalling because it helps distinguish urgency and meaning, but the symbol itself remains important where colour alone is not enough.
