Parents trying to take demerit points for their children were among the drivers found guilty of misleading police after another crackdown.
Sixteen drivers, predominantly aged between 40 and 66, were found guilty in Perth Magistrate's Court on Wednesday of trying to accept demerit point penalties that actually belonged to other drivers.
The false nominations led to charges of wilfully misleading police charges as part of the second round of Operation Glyder aimed at finding and prosecuting demerit point dodgers.
Nine people were fined $800 each and another seven received fines of $850.
In most of the cases, the false renominations were made by drivers to avoid getting demerit points.
In particular, some parents attempted to take the blame for children on restricted licences.
Eight people who were the true drivers of vehicles nabbed speeding have lost their licence as a result of the operation.
In the other cases the false renominations were made because the drivers were close to accumulating too many points.
Assistant Commissioner Nick Anticich said speed remains a contributing factor in too many crashes and the enforcement of such offending is critical to improving safety on WA roads.
"As a result of the latest round of investigations and court processes alone there are now eight more people who will lose their licences after having their demerit points allocated back to them, and this is in addition to the new court imposed penalties for misleading police," he said.
"Anyone who is considering an attempt to mislead us over speed camera infringements now need to think a lot more carefully.
"We are looking at driver nominations closely and we will investigate and prosecute when misleading information is provided to us."
Two drivers have elected to go to trial on their charges and three other cases were adjourned.
