Dust

This is what it looks like after a road train passes you going the other way.

The car in front stopped in the middle of the road, which is super dangerous. You should stop off the road before the train passes, or go at a reduced speed through the blindness for about 5-10s untill you can see again. Idiotic tourist driver, luckily we expected them to stop when we saw them enter the dust cloud.

On my way back to cairns.
