WA Police will review 53,000 speeding infringements after it was revealed a woman was wrongly convicted of driving at 162km/h on the freeway.

Eleven new mobile speed cameras have since been suspended due to a computer programming issue, with 20 cases known to have been affected by the false speed readings since January.

The software was found to have prevented the cameras from accurately determining the speed of vehicles travelling side-by-side. 

Testing prior to the roll out of the new cameras in January did not identify the issue.

A manual screening process identified and removed 19 of these cases with no infringements issued, but one case slipped through the screening process.

The woman was charged with reckless driving and her car was confiscated under hoon laws.

Prior to appearing in court, the driver disputed the speed reading and when the case was reviewed by police, the error was identified.

The vehicle was returned to the owner and the charge was withdrawn.

State Traffic Commander Scott Higgins said the police were now reviewing infringements previously issued from the affected cameras.

“We have checked all infringements resulting in vehicle seizures or court proceedings and we are satisfied these have been correctly issued,” Commander Higgins said.

“All other infringements issued by the new cameras are now being manually validated to ensure no-one else has been affected.”

He said the issue did not affect the remainder of the mobile camera fleet, the fixed cameras, the point-to-point system or red light cameras.

Recommissioned mobile speed cameras will maintain traffic enforcement until the upgrade is resolved and the new cameras are re-certified.
