No idea, we weren’t travelling that fast and it certainly wasn’t an emergency braking situation, the camera angle is very wide and we were closer than the video appears and I had no trouble stopping without excessive braking.
No load on the trailer but running off to the side is a worry as you often see people stopped there taking pics albeit a silly place to stop.
Theres been a few in NSW , they bought in a new law that you have to slow to 40 k if passing a vehicle police or ambulance that is on the side of the road with their red and blue flashers going. problem is in a 110 k zone cars are breaking because they see the lights and break and the truck etc only sees them a second later and the car is trying to get to 40 k and the truck at 110 k cannot stop as quick , stupid law and should be scrapper in its present form
Meanwhile in Qld, revenue from traffic fines is set to pass 500m per year.
