A method and an Intelligent Transportation System “ITS” module (110) for handling an ITS message are disclose. The ITS module (110) is configured for sending the ITS message over at least one of a second ITS station interface and a first ITS station interface towards an ITS station (121) and over an ITS server interlace to an ITS server (130). The ITS module (110) receives (A040) information relating to the ITS message over the second ITS station interface or the ITS server interface. Then, the ITS module (110) determines (A060) to send the ITS message over at least the first ITS station interface when the information relating to the ITS message was received over the second ITS station interface or the ITS server interface. Next, the ITS module (110) sends (A070), towards the ITS station (121), the ITS message over said determined at least the first ITS station interface. A corresponding computer program and a computer program carrier are also disclosed.
