A shoplifter trying to speed away from a New Jersey Walmart hit the same motorized shopping cart twice — before finally crashing head-on with a police car, police said Monday.

Siedah Smith, 34, fled the Bayonne store on Sunday afternoon, racing to her white car after a staff member tried to stop her from stealing shopping worth $235, according to the Bayonne Police Department.

Her getaway was soon stopped when she ran into a motorized shopping cart driven by an unidentified elderly man, police documents show.

After a yelling match with her victim, Smith again tried to flee after seeing a squad car responding to the initial shoplifting call, the docs say.

Somehow she managed to hit the same man, dragging him and his cart at least 10-foot — before finally smashing head-on into the police cruiser, according to the arrest report.

“Maybe I shouldn’t have parked here,” one of the officers quipped, according to a source who said there was minimal damage.

Smith, of Jersey City, was arrested and the elderly man she twice hit taken to the Bayonne Medical Center. His injuries were said to be “road rash”-style wounds from being dragged, sources said.

Smith was hit with a slew of charges including robbery, aggravated assault and hindering apprehension, along with aggravated assault with a weapon for the use of her car, police said.

She had tried to get away with a cart full of shopping by using a receipt she found in the garbage to claim she had paid for everything, according to the arrest report, with a source calling it “common practice” among shoplifters.
