Roachie - In W.A., the open road speed limit is 110kmh for all cars and trucks up to 12,000kg GVM.
However, once you couple a trailer or caravan to any car or truck, the speed limit of the combination in W.A. is 100kmh.
In W.A., the speed limit for heavy commercial vehicles with a GCM over 12,000kg - and buses & coaches with a GVM over 5,000kg - is 100kmh.
In the city and suburbs, you must give way to the public transport buses (the green ones) indicating to pull out of bus bays. They all have signs on the rear reminding you of this law.
Merging laws have been changed recently, along with road markings. Formerly, merging lanes had unbroken lines and you were not allowed to merge until the unbroken line ended.
Merging lanes now have a broken line, and you are allowed (and encouraged) to merge promptly over the unbroken line, exactly as with regular road marking lines.
The merging vehicle is to be brought up to speed with the traffic it is merging with, and then to be moved across the broken line into the main lane, as quickly as possible.
You are encouraged not to wait until the merging lane is ending before commencing your merging movement.
As always, the vehicle in front has right of way - provided your merging (or lane-changing) move doesn't make the vehicle behind brake heavily, and there is room to slot in between vehicles in the lane to the right.
Drivers Handbook - W.A.W.A. Merging rules
You'll find a lot of W.A. drivers are pretty bad drivers, with a regular lack of lane-change indication, failure to use or incorrect use of indicators at roundabouts, and tailgating and aggressive driving a regular habit.
Cheers, Ron.
