Does mobile phone ban apply to e.g. CB radio?

Hi Is there actually almost everything in the subject matter. But the question is formulated a little bit more precisely: What does it look like with regard to “handy ban at the wheel” actually with CB systems or LPD/PMR radios? Are they also under the prohibition or are the other regulated? So suppose I have to chase a truck after me now (absolutely confusing distance over the villages, truck drivers totally uninformed, only 1 person per day), I can do the whole via LPD radio (only PTT-Tast) e, unfortunately no headset or Vox function.) or did I then possibly draw the famous Ar*** card? Thanks already Crosscarrot
