Which is more difficult, C1 or B2?

[VanAlex]

B2 is more difficult, as the larger the permitted vehicle type, the greater the difficulty. The following introduces the relevant content for upgrading to B2: 1. Conditions: To upgrade, you must pass all subject tests for B2, from Subject 1 to Subject 4. You need to have held a C1 driver's license for at least 3 years before upgrading to B2, including the probation period, totaling three years. 2. Additional items: Subject 2 will include many additional items, such as single-plank bridge, width-restricted gate, undulating road, and U-turn on narrow roads. 3. Issuance of a new license after passing the test: You can drive trucks corresponding to the permitted vehicle type. For drivers engaged in professional driving, upgrading to a B2 driver's license is very necessary.
