Cops Rescue Pregnant Woman From Out-of-Control Car

It's a scary ride that a mom-to-be will never forget. A pregnant woman called 911 saying she was in a runaway vehicle. She says her car brakes would not stop and she was heading towards a lake. Cops pulled a tricky maneuver called a "rolling roadblock." The plan was to have a patrol car pull in front of the pregnant woman's car and gradually slow down until bringing it to a halt with a gentle bump. Afterwards, cops raced over to the car to find the woman was not hurt.
