“We were driving along a 4 lane state road and the car suddenly applied the brakes hard and swerved to the right. A light blinked on the dash with a picture of the car and a red line on the right hand side. No cars were in the next lane over and there were no issues with the roadway. I was driving straight in the line and not near the left hand side of the Lane.”
