Claim:
A device for controlling the height of an air deflector relative to a load or load carrier behind the cab of a truck, which device comprises a power operated sensor supported on an outside of the cab, the sensor being arranged to vertically scan the load or load carrier to sense an uppermost point of the load or load carrier behind the cab and to send signals representing the uppermost point to an indicator inside the cab, wherein the sensor is supported on a rear portion of an air deflector which is pivotally supported on the roof of the cab, the air deflector being provided with power operated means arranged to enable movement of a rear edge of the air deflector between an upper end position and a lower end position and adaptation of a height of a rear edge of the air deflector to the uppermost point of the load or load carrier in response to a signal from the sensor, the sensor having a range set to sense the uppermost point of the load or load carrier between the upper and lower end positions of the air deflector.
