Each respective first vehicle unit and respective one or more second vehicle units comprises a respective alerting unit out of the plurality of alerting units. The method comprises obtaining (301) movement data from at least one data communicating unit comprised in any one of the one or more combination vehicles. The movement data is indicative of one or both of a current movement or an expected movement of the one or more combination vehicles. The method further comprises, based on the obtained movement data, determining the current movement and/or the expected movement of the one or more combination vehicles. The method further comprises, when any one or both of the current movement and the expected movement is non-zero, and when any one or both of the current movement and the expected movement of the one or more combination vehicles is/are less than at least one predetermined threshold, triggering a sound alert on the plurality of alerting units.
