Nicole Harper, 38, is suing Rodney Dunn, an Arkansas state trooper, due to a traffic occurrence. When trooper Rodney Dunn employed the “mobile PIT”—short for pursuit method—last year, Harper, who was two months pregnant at the time, claimed she thought she might lose her baby, according to NBC News.

The future mother-to-be was clocked doing 84 mph in a 70-mph zone. However, she said she was trying to find a safe spot to pull over, reports the NY Post.

For more than two minutes on July 9, Dunn was trying a  “PIT maneuver”—short for pursuit intervention techniqueHarper on US-167 in Jacksonville when he nudged the back of her SUV with his cruiser—causing Harper to suddenly turn left and out of view of the dashcam. Harper’s SUV hit the median and was captured on video after it was stationary, flipped onto its roof.

Andrew Norwood, her barrister, described it as essentially a bowling alley with bumpers on both sides. There was no other option. Concrete barricades surrounded both sides of her car. He described the Arkansas state trooper’s act as “reckless” and said he created a serious risk of physical harm

Even though her own doctor could detect the fetal heartbeat the next day, a doctor at the emergency hospital the night of the accident told Harper he couldn’t.

Harper was accused of speeding and failing to stop for an emergency vehicle. Her lawsuit was filed last month in Pulaski County Circuit Court.

A spokesperson for Arkansas state police refused to comment to NBC.
