How long does it take to upgrade from a C1 driver's license to a B2?

[VanAlessandra]

You need to have held a C1 license for more than one year and have no full-point demerit record in the most recent scoring cycle before applying (must be at least 21 years old) before you can pay fees at a driving school, register, take exams, and upgrade to a large truck B2 license. Below is relevant information about the B2 license: 1. Exam content: The B2 driver's license test mainly includes three components: traffic regulations and related knowledge, field driving, and road driving. The exam sequence follows traffic regulations and related knowledge (Subject 1), field driving (Subject 2), and road driving (Subject 3) step by step. 2. Passing standards: A score of 90 or above is required to pass the traffic regulations and related knowledge test. For the field test, vehicle driving must be performed at a designated site, with only pass or fail evaluations. Road driving requires actual vehicle operation on highways or simulated sites, with large buses requiring 90 or above, large trucks requiring 80 or above, and other vehicle types requiring 70 or above.
