No Standing Down Under

Continuing with Darren Hodges on our international trip we head to Australia. Messr. Hodges runs a signspotters website. The circled "S" wasn't obvious to me and luckily Hodges pointed out that it means no standing, or stopping.



I appreciate Hodges solution to this sign, vearing away from the more obvious but ultimately more boring solution that could have been provided.

$$8 + 4 - 3 = 9$$

This sign is located in Stratford, Victoria.
