Shade, as I said, I’m no expert on the aussie highway code, so am prepared to bow to your greater knowledge on this one.
Different matter in the UK. In response to how do I know it’s a motorway, the truth is, it really doesn’t matter as in the UK all goods vehicles exceeding 7.5t gvw (and any vehicle drawing a trailer) are prohibited from using the third lane of any dual carriageway as they are debarred from the maximum legal speed and would therefore be potentially guilty of obstruction.
As for the 22t, I’m only going by the commentary, which you said you didn’t get, so fair do’s. (In truth I thought it looked way over that as well). I’m also prepared to accept the point about it potentially being a slip road.
At the point at which the car is struck, it is alongside a saloon car on the inside lane, which would clearly indicate that it had already completed it’s lane change.
Also it is perfectly legal and standard practice to move “out” into the middle lane to overtake traffic on the inside lane, which is what the merc was doing, hence being alongside the car it was overtaking when it was struck.
The truck was moving “inside” to undertake the vehicle the film is being taken from.
Hope this makes my conclusion a little clearer
As for blind spots, mirrors are adjustable. Therefore, depending on who is driving and the position of their mirrors, a blind spot will differ slightly from vehicle to vehicle and driver to driver.
As such, it is the drivers responsibility to check his blind spot(s) before he manoeuvres, not the responsibility of other road users to know where the truck drivers blind spot is.
Long story short, RTA he say no sale, truck drivers fault.
All in all that’s a bloody long response about a hypothetical accident.
