We Are The Most Environmentally Friendly Tourists

It would make a lot of sense increasing the max B licence weight to 4.23T for leisure vehicles . But they have managed to fudge the issue by increasing the weight for Alternatively fuelled vehicles only .... let's hope this can be changed , maybe a mail to your MEP for those of us that still have them .

The Commission issued on 1 March their proposal for a revision of the 3rd Driving Licence Directive 2006/126/EC.
However, it falls short as only alternatively fuelled vehicles (EV's) will be allowed to benefit from the extended driving licence category B to 4.25 t.

Currently, the European Caravan Federation are lobbying hard that the B driving licence up to 4.25 t must be accessible to all vehicles
