How do you spell the sounds of a police car?

You can't spell the sounds of a police car! They're just sounds, not words.

We can *describe* the sounds though:

* Siren: A high-pitched, wailing sound that changes pitch, often described as "woo-woo-woo" or "wee-ooh-wee-ooh".

* Engine: A loud, powerful rumbling sound, depending on the type of car.

Let me know if you'd like me to describe other sounds!
