Washington state trooper catches driver using mannequin in carpool lane The motorist was ticketed for the violation as well as speeding.

 -- A Washington State Patrol trooper who spotted a motorist violating the rules of the road is no dummy.

The eagle-eyed trooper spotted a driver attempting to outsmart the high occupancy vehicle lane policy by passing off a mannequin as a passenger.

HOV lanes are reserved for carpools, buses, motorcycles and any other vehicles carrying two or more people.

"Early this morning, a Tacoma trooper caught an HOV violator driving 81 mph with this young lady in the passenger seat," read a post on the Washington State Patrol's Facebook page, along with a photo of the lifelike violation. "In case you didn't know ... this doesn't qualify for HOV lanes!"

Trooper Todd Bartolac, a public information officer with Washington State Patrol, tweeted, "Violator was ticketed for speed and the HOV violation. On the positive side they were both wearing their seat belts! #buckelup"

According to the Washington State Department of Transportation, state troopers use their discretion to determine whether to issue a ticket or a written warning. The state's current fine for illegally driving in an HOV lane is $136.

Bartolac said the mannequin was one of the most lifelike he has ever seen, according to ABC affiliate KOMO in Seattle.
