Don't know what it is about that area mate, but I was booked for speeding because of poor signing on the same motorway. Out of the blue comes a 40km/hr sign from a 100km/hr zone. I was like What The and instantly took the foot off the gas looking where the roadworks crew were.
Next thing I have the blue flashers up my behind (literally seconds from when I first saw the sign). I argued and argued that you can't expect someone to safely go from 100km/hr to 40km/hr in the time I had. I was pointing to the sign saying you have to be kidden me look at where we are now mate!!! Probably abt 300m-400m back.
Long story short, he did me for 10km over the limit instead of 40. But yeah, I wasn't a happy chappy. lol
My only speeding fine in the last 11 years.
I find out later that they must by law decrement the speed from 100 to 80 to 60 then to 40
