There is no EC legislative proposal currently in preparation concerning mandatory use of Intelligent Speed Adaptors. No such proposal is foreseen.
The Commission has supported past research into ISA. There is a current stakeholder consultation and study focusing on speed limiting technology already fitted to Heavy Goods Vehicles (HGVs) and buses. One aspect of that is whether ISA could in the long-term be an alternative. A second consultation looks more broadly at in-vehicle safety systems in general.
