Upgrading from a C1 to a B2 driver's license requires taking an exam. The exam process is as follows: To upgrade from C1 to B2, you must start from the beginning with Subject 1. The content for Subjects 1, 3, and 4 remains the same, which are the theoretical test, road test, and safe driving knowledge test, respectively. As for Subject 2, it includes the following: pole test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, right-angle turning, narrow gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turn, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnel driving, driving in rain (fog), slippery road driving, and emergency situation handling. The specific process for applying for a B2 driver's license: Apply to the Vehicle Management Office for upgrading to a B2 driver's license; fill out the application form, submit your ID card and physical examination form, and provide the original copy of your current driver's license; attend the theoretical and practical exams as scheduled; upon passing the exams, the Vehicle Management Office will issue the new-level driver's license within 7 working days.
