Tire Pressure Light (TPMS) Meaning & Symbolism

The ⚠️ Tire Pressure Light (TPMS) symbol means one or more tires is significantly under-inflated — the horseshoe-with-exclamation shape. Driving on low tires ruins them and hurts braking. Once you know it, you will notice it everywhere.

Origin & History

The Tire Pressure Light (TPMS) (⚠️) comes from ISO 2575 standardized vehicle symbols, universal across car brands. Color tells urgency on every dashboard: red means stop or safety-critical, amber means investigate soon, green/blue is just information. Check all four tires plus the spare within a day; inflate to the door-jamb sticker, not the tire sidewall.

Modern Usage

Every modern car uses these ISO-standard symbols, so the same light means the same thing in a Toyota, a BMW, or a rental you have never driven.
