Read about - Wills Developmental Road below.
We travelled on the Wills Developmental Road in Queensland from Burke and Wills Roadhouse to Gregory Downs. This section of the road was sealed with some sections single width. We were advised to pull off to the side when a road train approaches (on single width roads) and allow the truck to stay on the tar - reduces the amount of gravel and dust thrown in the air. We thought this was good advice and always indicated well in advance to show the oncoming truck that it was our intention to pull over for safety.
