People have noticed there's something not quite right about WA's first point-to-point speed camera trial location.
As broken by WAtoday in February, the cameras were installed in October along Forrest Highway - Perth's gateway to the South West - in technology that allows two cameras to track a driver's average speed over a 26 kilometre stretch of road.
Those found to have exceeded the 110 kilometre per hour limit will be issued a fine.
But some drivers have questioned the position of the cameras since the trial was rolled out.
That's because the 26-kilometre zone happens to include the only two roadhouses along a 130 kilometre stretch of road between Baldivis and Bunbury - making those who stop for a snack or to fill up their cars essentially immune from getting a speeding ticket from the new cameras.
A Road Safety Commission spokeswoman said the committee responsible for picking the location of the cameras was aware the zone included the Gull Myalup Roadhouse heading north and Settlers Roadhouse heading south but the location was earmarked for safety reasons.
"The 26 kilometre stretch of road on Forrest Highway was chosen in response to a high number of road crashes that resulted in deaths and serious injuries," she said.
"An assessment of traffic volume and speeds was conducted as part of the decision making process, which demonstrated sufficient traffic volume and continuous speed for the average speed camera system.
"A steering committee of senior government representatives including WA Police, Department of Transport, Main Road WA, Road Safety Commission endorsed the section of Forest Highway for the average speed cameras."
The Commission said it does not compile data on the number of people who stop at the roadhouses within the zone but determined there was sufficient volumes of continuous traffic through the area to support the trial.
New legislation allowing police to infringe motorists who speed through the zone is not expected to be passed until after the March state election, with the cameras likely to be enforceable by July, 2017.
