(11)The specific characteristics of electronic road toll systems which are currently applied to light-duty vehicles should be taken into account. Since no such electronic road toll systems currently use satellite positioning or mobile communications, EETS providers should be allowed, for a limited period of time, to provide users of light-duty vehicles with OBE suitable for use with 5,8 GHz microwave technology only. This derogation should be without prejudice to the right of Member States to implement satellite-based tolling for light-duty vehicles.
