Method for operating a driver assistance system for a first vehicle located on a first driving lane (12.1) of a road that furthermore comprises at least one second driving lane (12.2) adjacent to the first driving lane (12.1), in which operating data and environmental data of the first vehicle are captured, a lane-changing intention for the first vehicle is determined, a driving instruction signal for performing a lane change of the first vehicle from the first driving lane (12.1) to the second driving lane (12.2) is determined in dependence on the captured operating data and environmental data of the first vehicle , a control signal for a light distribution with at least one light symbol (11.1, 11.2, 11.3, 11.4) is generated by the first vehicle in dependence on the driving instruction signal, through which control signal it is signalled to a driver of the first vehicle that the lane change can be performed safely, wherein the light distribution is presented for the driver of the first vehicle on the road on the basis of the control signal, wherein the light distribution is presented in two regions, wherein a first region is located on the first driving lane (12.1) and a second region is located on the second driving lane (12.2), characterized in that the driving instruction signal comprises a prepared light distribution as indication of a recommended speed change of the first vehicle , which is presented on the first driving lane (12.1), wherein the light distribution for the lane change is presented subsequently to the presentation of the prepared light distribution , wherein a transitional presentation is produced that is presented after the prepared light distribution and before the light distribution for the lane change. operating data and environmental data of the first vehicle are captured, a lane-changing intention for the first vehicle is determined, a driving instruction signal for performing a lane change of the first vehicle from the first driving lane (12.1) to the second driving lane (12.2) is determined in dependence on the captured operating data and environmental data of the first vehicle , a control signal for a light distribution with at least one light symbol (11.1, 11.2, 11.3, 11.4) is generated by the first vehicle in dependence on the driving instruction signal, through which control signal it is signalled to a driver of the first vehicle that the lane change can be performed safely, wherein the light distribution is presented for the driver of the first vehicle on the road on the basis of the control signal, wherein the light distribution is presented in two regions, wherein a first region is located on the first driving lane (12.1) and a second region is located on the second driving lane (12.2), characterized in that the driving instruction signal comprises a prepared light distribution as indication of a recommended speed change of the first vehicle , which is presented on the first driving lane (12.1), wherein the light distribution for the lane change is presented subsequently to the presentation of the prepared light distribution , wherein a transitional presentation is produced that is presented after the prepared light distribution and before the light distribution for the lane change. <EOS>
