Sounds like xplosys needs an Aussie/EU Road rules lesson. lol
In aus, the most common line, is this - - -. That one means that both lanes can overtake. sometimes, you will see on like this
________ This means that only the side with the dotted line can
- - - overtake, and this is most common on a corner, with the outside lane inable to pass. Then ofcourse there is this line ===== (no gaps) meaning no lanes may pass. This is most common arround a hill, or windy road.
The only yellow lines in australia, as far as i know, are along the sides of the footpath, meaning that oyu cant park in that location, or some parking spots marked out in yellow, etc.
You always drive on the left hand side, and the driver sits on the right hand side of the vehicle.
Thats pretty much the road rules of Aus
ONe more thing, if you see a Roo on the road, if your more than 50 meters, brake slowly and honk, if your less then 30 meters at first sight, dont slow down, speed up, and avoid if possible
HAve a nice day
(sorry if I made you feel like an idiot in this message or anything)
