Trike with B driving licence

Hello. I’m trying to find information about whether I can ride a trike with my car driver’s license. The new rule says yes, that after 2013 all trikes are considered motorcycles. Only if you have made the car driver’s license before 2013, can you move a trike with these. I made my 2006. Today I looked at a Piaggio MP3 250. This is from 2007 and has no foot brake but a lane spread on 460mm. In the registration it says that the bike with the Ke The dealer has now explained to me the following: Before the new driver’s license rule, the bike was probably approved as L5E. The bike was registered in 2014 and registered in 2015. However, since today all trikes are considered motorcycles, they are also registered with the L3E identification number and you can still move them with the old B driver’s license. He also tells me that the condition of the foot brake has now fallen away. In fact, I have now found nowhere in the new rules. and that there must be a foot brake. What is the state of things now? Can I ride the bike?
