Signs for role play outside

i would like 12 signs that fit in the middle of this stand for children to use in the playground with trikes. I am open as to what they could be but here are suggestions. the sign would go at the side of the track. the more realistic the better.its for 3-5 year olds

1. building site sign – safety at work
2. wipe clean sign that you could write a shop of something on so just a strong border
3. roadworks(if it looks sufficiently different),
4. mechanics and petrol garage.
5. road chevron sign (the arrows)
6. blank roundabout sign,
7. Grand prix signs - Finish sign,
8. pit stop sign,
9. airport
10. carwash
11. taxi office
12.

The signs i want to be boy friendly ok to 7 years old and photorealistic, almost graphic but with a few icons also, and small spaces to write here and there.

I was going to simply find the photos on web and reprint them (all we need can be found on google image search) but then I thought it would be a fun one you’d enjoy if you had capacity.

I’m very open to other suggestions for these
