The grade of license required to drive a commercial vehicle weighing more than 3500 kilogram, attached to a trailer with weight of 4000 kilogram:
- C1.
- Correct answer: C+E.
- D.
- B.
Why this is the answer
The correct answer in the official bank: C+E.
When a heavy commercial vehicle tows a heavy trailer or semi-trailer, you need class C plus E, where E is the permit to tow a heavy trailer. Class B is for light vehicles, and class D is for buses. C1 alone is not enough for such a combination, because it does not include the towing addition E.
