vedaja kohustus tegevusloa alusel osutada kvaliteetset järjepidevat ühistransporditeenust ja vajaduse korral lisateenust ning kohustus pärast teenuste osutamise lõpetamist tagastada töökorras olekus temale lepingu alusel kasutada antud ühissõidukid ja liinirajatised
Alusdirektiivis tähistab sama mõtet mõiste 'obligation to carry' - any obligation imposed upon a transport undertaking to take, in respect of any route or installations which it is authorised to work by licence or equivalent authorisation, all necessary measures to ensure the provision of a transport service satisfying fixed standards of continuity, regularity and capacity. It also includes any obligation to operate additional services and any obligation to maintain in good condition routes, equipment - in so far as this is surplus to the requirements of the network as a whole - and installations after services have been withdrawn. {14.06.2000}
