(29)Through the adaptations of the AETR Agreement, the use of the digital tachograph has been made mandatory as regards vehicles registered in third countries which are signatories to the AETR Agreement. As those countries are directly affected by changes to the tachograph introduced by this Regulation, they should be able to participate in a dialogue on technical matters, including regarding the system for the exchange of information on driver cards and workshop cards. A Tachograph Forum should therefore be set up.
