Police said the Superior woman, who filed for divorce last July, caused traffic delays with her yard display Wednesday when she put out large signs reading "X-HUSBAND SALE" and "FREE" next to items purported to be his.
She had covered the GMC, which had flat tires, with words including "cheater" and multiple obscenities, the Duluth (Minn.) News Tribune reported Thursday.
Police had the sport utility vehicle towed away, but the rest of the lawn display was left intact, Sgt. William Lear said.
"If it's creating a disturbance, if there's threats, if it's blocking traffic, we can tow it," Lear said.
