A method for assisting a driver of a vehicle towing a trailer includes providing a rear backup camera at a rear portion of the vehicle. A trailer having a trailer tow bar is attached to the trailer hitch of the vehicle. The vehicle is driven while towing the trailer and image data is captured via the rear backup camera and provided to a control at the vehicle. The image data captured while the vehicle is towing the trailer is processed at the control to determine an angle of the trailer tow bar relative to the vehicle. Responsive to determining the angle of the trailer tow bar relative to the vehicle, a degree of sway of the trailer relative to the vehicle is determined. Responsive to determination that the degree of sway is greater than a threshold degree of sway, an output is generated via the control.
