Without Trucks

Delivery day today and the Truck had this sign on, i have seen it before but never had chance to take a photo.
I do not believe there is a truer sign in Australia, such a large country we rely on Trucks for so many things. We have rail but need the Trucks to transport goods to the railways, the same with Ships.
This is only a small Truck but some of them are huge how the drivers manage to manoeuvre them amazes me. If I was brave I would learn to drive one that wouldn't be too bad but parking one would be a bit different ,i cant even park my Mazda.
