I am browsing the mobile speed camera manual, located at http://snipurl.com/uzw6 It's interesting to read how they state that the cameras cannot be used in such and such a manner. Then add a clause that effectively nullifies that particular criteria. Eg: 15.1 Criterion 5: Sites must not require a camera vehicle (or tripod) to be position:- (1) In a way that it is likely to cause any interuption to the traffic flow; or (2) In contravention of the Road Rules - Victoria Here's the kicker: Consideration may be given to exercising the exemption contained in Rule 197 (1) (c) of the Road Rules in relation to stopping on pathways, dividing strips and nature strips. These particular rules regarding parking or stopping in such areas are usually safety reasons based. Yet, they'll happily contravene the rules of physics in order to allow them to park in such areas. One of the other rules that determine a camera's location is whether Police (rank of Snr Sgt or above) have determined that the area is experiencing significant levels of excessive speed. It doesn't say what "significant" may be. No quantifying figures are given. ie. would it be 5% of all traffic, 10%, etc.? It goes on to say that cameras can be placed at the bottom of hills, but they have to be of a grade where a vehicle on a trailing throttle doesn't experience significant acceleration. But, again, the rule says that this can be overriden if the police deem it necessary. Another one - cameras should not be placed on bends, except that where excessive speeding, as determined by police or written complaints, or incidents of serious crashes. That is where I copped a fine. I came around this corner and there was a speed camera facing me on the other side of the road. Road was Princes Hwy between Orbost and Cann River. As far as I'm aware, this particular stretch of road isn't all that dangerous. Of course, the authorities may disagree - that perhaps one or two people in the past 20 years have run off the road or something. Finally, the rules say that a camera may not be placed within 200m of a speed limit sign. But again, that may be overridden. Whatever, the point that I'm trying to get across is that there seems to be a legal "out" for all criterion that stop the use of cameras in specific situations.
