Directive (EU) 2019/520 of the European Parliament and of the Council of 19 March 2019 on the interoperability of electronic road toll systems and facilitating cross-border exchange of information on the failure to pay road fees in the Union (recast) (Text with EEA relevance.) Article 13

Single continuous service

Article 13

Member States shall take the measures necessary to ensure that EETS is provided to EETS users as a single continuous service. This means that: (a) once the vehicle classification parameters, including the variable ones, have been stored or declared, or both, no further in-vehicle human intervention is required during a journey unless there is a modification to the vehicle's characteristics; and (b) human interaction with a particular piece of OBE stays the same whatever the EETS domain.
