Police are warning drivers not to use mannequins as passengers to take advantage of carpool lanes after laying their latest charge.

A motorist was caught driving with a mannequin in the front passenger seat on the Highway 404 high-occupancy vehicle lane at around 9 a.m. Thursday, Ontario Provincial Police Sgt. Kerry Schmidt said.

“Officers were on patrol in the area and they were just watching traffic going by and they saw this car where it looked there was this passenger,” said Schmidt.

The officer on patrol, who himself was no dummy, realized that the “passenger” was merely plastic and brought the vehicle to a halt.

“They discovered a mannequin strapped up on the passenger side, wearing sunglasses,” said Schmidt.

An image posted by Schmidt on Twitter shows the female doll wrapped in a glittery brown scarf with perfect hair, likely because of the comb that was in her hand.

“There’s nothing illegal about transporting mannequins in your vehicle, but if you use them to take up privileges on the HOV lanes, that’s where we have an issue,” said Schmidt.

The penalty for improper HOV lane use is a $110 fine and three demerit points, according to the Ministry of Transportation’s website.

Incidents like these don’t happen often, Schmidt said.

“We have seen it in the past, but it’s not super common,” he said.
