About B licence: three limits at once: which statement is correct?

The mass, passenger and trailer limits of a B licence belong to the rules on licences with a restrictive code (e.g. for medical aids).

With a B licence you may tow any trailer, as long as the trailer itself is not overloaded.

Category B applies to vehicles for at most 8 passengers, excluding the driver, in addition to the mass limit.

From age 17 you may already drive independently with a B licence, just like with 2toDrive supervision.
