The Los Angeles Times reports ( http://lat.ms/13JaHZC) a video from the cruiser's dashboard was played in court, showing 30-year-old Tamara Gaglione forced to the ground violently after at least one officer approached her with his gun drawn.
She was pulled over in August 2011 for talking on her cell phone.
She was later charged with resisting arrest and driving with a suspended license, but those charges were dropped.
CHP officials declined comment on the suit, but confirmed the officers remain on the force.
Gaglione and her now 9-month-old son have since left Los Angeles.
