The officer stopped the van and discovered the driver's passenger was a mannequin dressed in sunglasses and a hoodie.
"This is one of those cases where the RCMP got their mannequin," police said. "The passenger exercised the right to remain silent."
"The driver of the vehicle was issued several tickets for the alleged offenses and the passenger, who did not protest, was given a ride to her new home...in a police car," police said.
Police said users of the HOV lanes must have at least two actual humans in the vehicle.
"In this case, the mannequin was seized to prevent the continuation of the offense of Illegal Use of HOV lane," RCMP said.
