I am looking for a pattern to knit a child’s sweater with an ambulance picture on it, can anyone help?

i couldn’t find any ambulances but I think this one could probably be turned into an ambulance fairly readily.

I also have to link to this little sweater which I’ve made twice now. It’s a fun pattern and a van here or there could become an ambulance.
