Core: B licence: three limits at once

You may apply for a B licence from age 18 (the law). It gives you access to motor vehicles with a permitted maximum mass of no more than 3,500 kg, built for the transport of at most 8 passengers, excluding the driver — two independent limits, not alternatives to each other. As soon as you attach a trailer, a third calculation model is added: up to 750 kg permitted maximum mass the trailer is always allowed. Is the trailer heavier? Then it is no longer the trailer alone that counts, but the combination of towing vehicle and trailer together — that must then not exceed 3,500 kg. Want to go heavier than that combination ceiling? Then a B licence with code 96 is needed, good for a combination up to 4,250 kg. These figures — 750, 3,500, 4,250 — are the same ones used elsewhere in the licence chapter for the full licence ladder (B96, BE, C1E); this atom covers only category B's own base definition. One precision point: the legal source for these three figures is the law, not the law — the latter concerns licences with a restrictive coding such as medical aids, a different subject.
