C1 license holders who wish to upgrade to a B1 license need to take three tests, which are: Subject 1 (Road traffic safety laws, regulations, and related knowledge test); Subject 2 (Field driving skills test); Subject 3 (Road driving skills test and safe civilized driving common sense test). C1 driver's license: The C1 driver's license is one of the motor vehicle driver's license codes. The scope of the C1 license includes small and micro passenger vehicles, light and micro cargo vehicles; light, small, and micro special purpose vehicles; and small passenger vehicles with a seating capacity of 9 or fewer people. Application age: The minimum age requirement for a C1 license is 18 years old, with no upper age limit. However, applicants over 70 years old must pass tests on memory, judgment, and reaction abilities.

Upgrading from a C1 to a B1 driver's license was no easy task. First, I had to retake the theoretical knowledge test for Subject 1, which covered traffic rules and sign recognition. The question bank was extensive, requiring daily practice to memorize everything. Subject 2 was the most challenging—practicing reversing into a parking space, navigating sharp turns, and starting on a slope at the training site. These maneuvers demanded precise speed control; even a slight mistake could lead to failure, so staying calm under exam pressure was crucial. Subject 3 was even more grueling, involving on-road driving tests, including nighttime driving. The examiner closely monitored lane-changing observations and proper parking techniques, with strict adherence to safety details. Finally, Subject 4 tested safe and civilized driving through multiple-choice and true/false questions, focusing on emergency scenarios. The entire process also included a medical check-up for vision, hearing, and color blindness. I highly recommend booking training sessions in advance and finding a reliable driving school for guidance—otherwise, a single mistake could mean retaking exams, wasting both time and money.

My child recently went through a rigorous process to upgrade their license to B1. The test consists of four main modules: Subject 1 is the theoretical part, testing basic traffic knowledge with moderately difficult questions that require thorough memorization; Subject 2 focuses on field driving skills, emphasizing techniques like hill starts, reverse parking, and curve driving, which demand repeated practice to master vehicle control; Subject 3 involves practical road driving in real environments, covering nighttime light usage and obstacle avoidance, highlighting adaptability; Subject 4 tests civilized driving etiquette and emergency case analysis to ensure strong safety awareness. A physical examination is mandatory to confirm physical fitness. The entire process demands significant time and effort, so it's best to allocate at least a one-month practice period to avoid rushing and failing the test.

The additional B1 license test consists of four parts: Subject 1 examines traffic theory knowledge through written or computer-based tests; Subject 2 assesses field skills such as reversing, hill starts, and S-curve maneuvers for operational precision; Subject 3 involves on-road driving covering urban road rules and nighttime scenarios; Subject 4 is a safety and civility Q&A test evaluating decision-making. The entire process from registration to obtaining the license typically takes several weeks, with a medical examination to ensure no health risks before approval.

Last year, I upgraded to a B1 license and deeply experienced the challenges of retaking all subjects, unlike the simpler process of downgrading. For Subject 2 (field test), maneuvers like parallel parking are prone to errors—practice more and maintain a stable mindset. Subject 3 (road test) now includes an intelligent scoring system that detects mistakes in turns and lane changes, which have a high error rate. Prepare by using simulators to familiarize yourself with vehicle performance and check tire and light conditions to avoid point deductions. Subjects 1 and 4 have a large question bank, so start brushing up two weeks in advance for higher efficiency. Don’t delay the medical checkup—submit it on time to avoid hindering overall progress.

After the update for upgrading to a B1 license, all subjects must be taken without exemption: Subject 1 theory question bank has been expanded to cover new regulations; Subject 2 field driving emphasizes details like preventing stalling on slopes; Subject 3 road test includes rain and fog simulation to assess safe avoidance; Subject 4 safety knowledge strengthens emergency handling skills. Physical requirements include vision above 5.0 and no history of epilepsy. Consult the local DMV to confirm the latest rules before applying. Maintain stable performance during practice to reduce sudden mistakes.
