An Ontario woman is facing criminal charges in a case police have dubbed "seatbelt rage."

A provincial police officer pulled a car over Thursday evening in Meaford, Ont., after noticing the driver was not wearing her seatbelt.

Police said the woman became "highly agitated," screamed and shoved the officer before throwing her documents on the ground.

Police said she indicated she was going to leave the scene so officers "took control" and she resisted arrest.

The woman was briefly held in custody but was then taken to hospital "out of concern for her volatile and irrational behaviour," police said.

Fine increased to $240

The 45-year-old woman from Town of the Blue Mountains, Ont., has been charged under the Highway Traffic Act with failing to wear her seatbelt and under the Criminal Code with assaulting police and resisting arrest.

She is scheduled to appear in court in Owen Sound on June 24.

Provincial police said the fine for seatbelt infractions has been increased to $240 and comes with two demerit points.

"Clearly, someone assaulting a police officer over a minor traffic offence is acting irrationally," Const. Steve Starr said in a statement titled "Seatbelt Rage."

"But officers have noted an increase in motorists venting on them after being charged with seatbelt offences, largely because of the increased fine."
