Mohammed Yasin Mulla claimed his windscreen was smashed when falling debris flew off the van in front of him on the M606 in Bradford, cracking his windscreen and damaging the bonnet and roof.
He also claimed he suffered injuries to his neck and shoulders after he had to swerve and brake suddenly.
But dashcam footage from his own car revealed a piece of polystyrene packaging flew towards his vehicle, and missed it.
The 38-year-old from Bradford, was found guilty of fraud by false representation by a jury at Leeds Crown Court following a trial.
He was sentenced to carry out 250 hours of unpaid work over a year, although he has lodged an appeal against his conviction.
Detective Constable Peter Gartland, who led the Insurance Fraud Enforcement Department (IFED) investigation, said: “This case shows that no-one is above the law.
“The IFED works to identify and punish fraudsters, irrespective of their profession.
“Police officers are expected to be honest and act with integrity, and the vast majority do, but cases such as this one threaten to damage the police’s reputation.”
Mulla remains on restricted duties while the force conducts its own investigation.
