WA Police has flagged possible legal action against a company which provided new-generation speed cameras that led to dozens of incorrect speeding fines while deployed on state roads.

Police entered into a contract with traffic safety solutions company Jenoptik in 2016 for new, state-of-the-art cameras which could provide higher-quality images and be able to better detect motorcyclists on the road.

But police were forced to review the use of the 11 cameras in April 2018 when a young mother was falsely accused of driving 162km/h on Kwinana Freeway and had her car seized for nine days under WA's 'hoon' laws.

Police Commissioner Chris Dawson later confirmed the Jenoptik speed cameras had resulted in about 50,000 infringements over their deployment period, all of which had to be reviewed when the software fault was detected.
