A device, transportation vehicle, and method for checking a calibration of surroundings sensors, wherein the surroundings sensors at least partially detect similar surroundings and provide mutually time-synchronized sensor data, periodic features at least for at least one distinguished area are detected in the sensor data of the surroundings sensors belonging to the same surroundings, a transformation of the sensor data corresponding to the at least one distinguished area to a frequency domain is carried out at least for the at least one distinguished area, a frequency and/or a phase angle of the periodic features is determined in the sensor data transformed to the frequency domain, a decalibration of the surroundings sensors is detected based on a comparison of the determined frequencies and/or of the determined phase angles, and a result of the check is provided.
