[MasonLynn]

C1 license cannot be directly upgraded to A1, because A1 is the highest-level driver's license for passenger vehicles. To upgrade to A1, you must first upgrade to a B license, and then you can upgrade to A1. The prerequisite for upgrading to B1 is to have held a C1 license for more than two years, be between 20 and 60 years old, have no record of 12 penalty points in the last two scoring cycles before application, and have no outstanding traffic violations. According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses' (Ministry of Public Security Order No. 123) of the People's Republic of China, the following conditions must be met to apply for an upgrade: To apply for an A1 (large passenger vehicle) license, you must have held a B1 (medium passenger vehicle) or B2 (large truck) license for more than five years, or have held a tractor license for more than two years, and have no record of 12 penalty points in the last five consecutive scoring cycles before application. If you hold a B1 or B2 license, you can upgrade to A1 under the following conditions: Have held an A3 or B1 license for more than two years, or a B2 license for more than three years, or an A2 license for more than one year. There should be no record of 12 penalty points in the last three consecutive scoring cycles before application, and the applicant must be between 22 and 60 years old. The A1 license allows driving large passenger vehicles and also permits driving vehicles under A3, B1, B2, C1, C2, C3, C4, and M license categories. A1 license test items: Subject 1: Driving theory test; Subject 2: Road stakes, slope parking and starting, side parking, single-sided bridge crossing, curve driving, right-angle turning, limited-width gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turn, simulated highway, continuous winding mountain road, tunnel, rain (fog) weather, slippery road, emergency handling—16 items in total; Subject 3: Preparing to get on the car, starting, driving straight, gear shifting, lane changing, pulling over, going straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, picking up passengers, overtaking, U-turns, night driving.
