Check your speeding infringement is valid (WA and other states with Poliscan camera)

Thanks for that plate close up BRD. I think that that white line is the one mentioned here ;

Additionally, the graphical template includes an auxiliary line which corresponds with a scale of 0.5m. It's vertical position visualises the sampling level.

So basically, that point on the car is where the Poliscan took it's readings from, which is why sometimes if the sensors are above the license plate on a parking sensor equipped car, you might get a failure to detect as the beam diameter is very narrow at this point. Thats why you need the max sensitivity proivided by the ALP over the LI etc.
