Thanks dave, I was reading that today and had no idea what the qld dd system was.
A 42yo friend of mine just got done for 20kph over limit in NSW [1st speeding offence] overtaking a semi which was doing 80-85 in a 100 zone on straight road, his defence will be what do i do??? over take him at the same speed ? Even overtaking him at 100kph is a little dangerous i would think, better to get out and around quickly and continue with no trouble then spending a few more seconds on the wrong side of the road. I really don't think it will hold up in court though.
