Meaning
A police car seen from the front, heading towards you with its roof light flashing. It stands for police arriving on the scene.
Use it for urgent or dramatic messages, or for jokes about someone being caught out: “Mum just found my report card 🚔 I’m done”. Its head-on view feels more immediate than the side-on 🚓. Pair with 🚨 for an alarm or 😳 when busted.
