Road Trains.

Road trains are a feature of many Australian roads. Each "train" is up to 53 metres long and consists of a "prime mover" and up to four trailers. They usually travel at 100kph and give way to no one!

On wide tarmac roads road trains are an interesting addition to the traffic. On dirt roads they are a significant hazard. If possible it is best to pull over and stop well off the road.
