To upgrade from a C1 to a B1 license, you need to pass three tests: Test 1: Examination on road traffic safety laws, regulations, and related knowledge; Test 2: Field driving skills examination; Test 3: Road driving skills examination and the safety and civilized driving common sense test, which is commonly referred to as Test 4. To upgrade from a C1 to a B1 license, you must have held the C1 license for at least three years and have no record of full penalty points in the three scoring cycles prior to application. Additionally, for those applying to upgrade to a medium-sized passenger vehicle, tractor, or large passenger vehicle license, the following regulations must be met: Applicants for a medium-sized passenger vehicle license must have held a license for urban buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, or three-wheeled vehicles for at least three years, with no record of accumulating 12 penalty points in the three consecutive scoring cycles prior to application.

I just upgraded my license from C1 to B1, and the whole process was quite challenging. The test consists of four parts: theory test, yard test, road test, and safety test. The theory test covers traffic rules, similar to C1 but with more in-depth content, requiring knowledge about larger vehicles. The yard test was the most difficult for me, involving tasks like reverse parking and hill starts in the training yard. Since B1 vehicles are much larger than regular cars, the handling is completely different, and it took me several days to get used to it. The road test involves actual driving on the road, where the examiner checks lane changes, turns, and emergency handling, and I had to constantly watch for blind spots. The safety test includes new content on civilized driving. I recommend enrolling in a driving school for systematic learning—the whole process takes about two weeks. With a B1 license, you can drive medium-sized buses, which is great for road trips or part-time driving jobs.

I'm familiar with the process of upgrading from a C1 to a B1 license. The test consists of four parts: theory, field, road, and safety. The theory test focuses on regulations and vehicle condition awareness, with a broader question bank than the C1, such as calculating braking distance. The field test includes reverse parking and fixed-point stopping, where the larger vehicle body and smaller turning radius can easily lead to mistakes. The road test assesses parallel parking and emergency avoidance in real environments, and I recommend familiarizing yourself with the route in advance. The safety test covers accident prevention and emergency measures. The entire process requires a medical certificate and being at least 21 years old, with no major traffic violations. Using specialized courses at driving schools during practice can improve success rates, taking about ten days. After completion, you can drive medium buses or commercial vehicles, which is highly practical but requires serious preparation.

I want to upgrade my driver's license from C1 to B1. I heard the test is quite simple. There are four parts: the theory test is similar, with some additional knowledge about large vehicles; the yard test includes reversing and slope driving, which I learned by watching online videos for a few hours; the road test involves driving a regular route, just don't speed; and the safety test covers civilized driving rules. The key is to practice more with simulation apps and get hands-on practice at the driving school. No need to be too nervous. You can get the license and drive fleet vehicles soon.

I have extensive experience in upgrading to a B1 license, mainly covering theory, field skills, road driving, and safety knowledge. The theoretical content includes detailed traffic regulations; field test items such as S-curve reversing require precise control; the road test emphasizes daily driving habits—I always check tire pressure to avoid malfunctions; the safety test focuses on accident prevention. The B1 license is suitable for those who need to drive buses for work, with an age requirement of 21 or older, ensuring safety first throughout the process. When preparing, using a question-brushing app is helpful, and 3-4 real-vehicle training sessions can boost confidence.
