The requirements for upgrading from a C1 license to a B1 license are: 1. To upgrade to a B1 driver's license, you must have held a C1 license for at least 3 years; 2. The applicant must be between 21 and 50 years old, with a height of at least 155 cm; 3. No full-point penalty record in the last 3 scoring cycles before application; 4. The information on ID card, driver's license, and address must be consistent. The materials required for upgrading from a C1 to a B1 driver's license are as follows: 1. Application form for motor vehicle driver's license; 2. Original motor vehicle driver's license; 3. Original and photocopy of the applicant's identity proof; 4. Medical certificate issued by a county-level or higher medical institution or a military regiment-level or higher medical institution; 5. Eight recent color front-facing photos of the driver with a white background, bareheaded, and the head occupying two-thirds of the length.

I recently upgraded my driver's license from C1 to B1, and I'm really excited! Remember, you need to have held a C1 license for at least 3 years. I've been driving for 5 years with no issues, and the age requirement is 21 or older—I just had my birthday so I qualified. The medical check-up is crucial; don't take the vision and hearing tests lightly. My advice is to get a pre-check at the hospital to ensure everything goes smoothly. The exam has four parts: first, a written theory test—I reviewed traffic regulations; then, a field practice where you need to master reversing and turning; a road test for actual driving; and finally, a simulation of emergency situations. After the upgrade, I can drive medium-sized buses, making it more convenient to help friends or tour groups. The whole process took two months, and consistent practice was key. Sharing my experience to help others avoid pitfalls.

My experience upgrading from C1 to B1 is quite practical: You must hold a C1 license for at least 3 years, be over 21 years old, and have no record of serious accidents. For the physical examination, normal vision is required, and wearing glasses is acceptable. The exam process is crucial—you need to pass the Theory Test (Subject 1), Field Skills (Subject 2), Road Practice (Subject 3), and Safety & Civility (Subject 4). I recommend reviewing study materials in advance and staying patient and calm during the test, as driving larger vehicles requires a different spatial awareness. After upgrading, you can drive with a larger team, making it more lucrative during peak travel seasons—definitely worth it. In short, ensure all conditions are met before applying to save time and hassle.

When upgrading to a B1 license, I prioritize safety first: the basic requirements are 3 years of driving experience with a C1 license, being at least 21 years old, and no major accidents in the past three years. The medical examination checks vision and physical health to ensure the ability to safely operate large vehicles. The test includes both theoretical and practical sections, for which I prepared by reviewing study materials and enhancing my practice in handling large vehicles. After upgrading, I can drive medium-sized buses, which increases flexibility but also risks, so everyone must adhere to speed limits.
