TACOMA, Wash. -- Guess you could call her HOV Barbie.

A Washington State trooper based in Tacoma caught another one of those folks who put a mannequin in the passenger seat to cheat in the carpool lane Friday.

WSP says the cheater was doing 81 mph in the HOV lane with the dummy in the right seat. A photo tweeted by WSP shows the offending model is blonde, wearing a pink top and a pink headband -- similar to a Barbie doll.

WSP didn't immediately say how much the driver was fined, but when you combine breaking the HOV rules and breaking the speed limit by 21 mph, it's probably going to be pretty hefty.

But at least they didn't also get hit with fine for not wearing their seat belts.
