An alcohol interlock device is a system installed in the vehicle to prevent a driver impaired by alcohol from operating the vehicle. Introduction of a code on such devices has been requested by Member States and recommended in a study.
Several Member States already have such restricted licences, but currently the codes vary between Member States and cannot be understood nor enforced in other Member States. The main purpose of this new code is to facilitate EU-wide understanding and to make it enforceable EU-wide.
It is important to note that this code is only to be used by the Member States who issue licences with this restriction. There are a lot of Member States who do not have alcohol interlocks and thus do not issue licences with such restrictions. They can continue to do so.
