Polizzi, in Florence to tape the fourth season of "Jersey Shore," was driving when she rear-ended the patrol car. A witness told TMZ that the crash wedged Polizzi's car between the police car and a highway wall.
Her "Shore" costar Jenni "J-WOWW" Farley, who was riding in the car with Polizzi when the crash occurred, reportedly had to exit the car through a window because the door was blocked by the wall.
No one was injured in the incident. A source close to the production said "zero alcohol was involved."
Officials in Florence have banned the "Shore" production from shooting at some of the most famous locations in the Renaissance city, including the renowned Uffizi gallery and the sculpture-filled Boboli Gardens.
Mayor Matteo Renzi also declared the show's stars must not be filmed in bars and clubs that serve alcohol and must not be filmed drinking in public. He said he wanted the show to promote Italy and feature its culture, traditions and good food.
