A driver assistance system for a vehicle includes an imaging sensor and a control. The control processes image data captured by the imaging sensor to determine the presence of an object of interest in the scene monitored by the imaging sensor. The control adjusts a vehicle accessory and/or headlamp of the vehicle at least in part responsive to determination of the presence of the object of interest in the monitored scene. The control receives vehicle data via a communication bus of the vehicle, with the vehicle data including at least one of (i) vehicle speed data and (ii) vehicle trajectory data. At least in part responsive to receiving vehicle data, the control inhibits adjustment of the vehicle accessory from a first state to a second state. The control is operable to process captured image data to determine the presence of lane markers in the monitored scene.
