In a method for operating a vehicle, a planning map and a localization map are provided, the vehicle is localized on the localization map, a map corridor indicated in the planning map is selected based on the localization, a sensor corridor is ascertained using a sensor unit of the vehicle, and the map corridor is compared to the sensor corridor. Using a specified threshold value for a deviation between the map corridor and the sensor corridor, it is decided whether the map corridor and the sensor corridor are identical. The map corridor is utilized for operating the vehicle if the map corridor and the sensor corridor are identical, and the sensor corridor is utilized for operating the vehicle if the map corridor and the sensor corridor are not identical.
