A trailer-detection system includes a radar sensor, an angle detector, a camera, and a controller. The radar sensor is used to determine a range and an azimuth angle of a radar signal reflected by a trailer towed by a host-vehicle. The angle-detector is used to determine a trailer angle relative to the host vehicle of the trailer towed by the host vehicle. The camera is used to detect a lane marking of a roadway traveled by the host vehicle and trailer. The controller is in communication with the radar sensor, the angle detector, and the camera. The controller is configured to determine when the trailer is departing from a travel lane of the roadway based on the radar signal, the trailer angle, and the lane marking.
