You can apply for an upgrade if you have no demerit points within one year. Below are the relevant details: Article 14: If you already hold a motor vehicle driver's license and apply to add an additional permitted vehicle type, you must not have accumulated 12 demerit points in the current scoring cycle or the most recent scoring cycle before the application. Situations where an upgrade is not allowed: being held equally or more responsible for a traffic accident resulting in death; driving under the influence of alcohol leading to license revocation or having a motor vehicle driver's license revoked for less than 10 years. Vehicles permitted with a B2 license: A B2 license allows driving heavy-duty, medium-duty cargo vehicles or large, heavy, and medium-duty specialized operation vehicles. Heavy-duty and medium-duty cargo vehicles are mostly trucks, such as the large dump trucks commonly seen on roads carrying construction debris, which fall under the category of heavy-duty trucks.

When my B2 driver's license was downgraded to C1, I consulted with driving school staff who said I'd need to wait at least three years before applying to upgrade back to B2. During this period, my driving record had to remain completely clean without accumulating 12 penalty points, otherwise the waiting period would extend. As someone who tends to chat while driving, a rear-end collision directly caused my downgrade. After waiting the full three years, I had to retake both the theoretical and practical exams, which was quite a hassle. I believe drivers should stay more focused with safety as top priority to avoid such troubles. The actual license upgrade process also required advance registration for training, queuing for exams - overall time-consuming and laborious but worthwhile, as I now drive heavy vehicles more steadily.

As a long-time driving enthusiast, I've studied the driver's license regulations. To upgrade back to a B2 license after a downgrade, the official requirement is to hold a Class C license for at least three years, ensuring no major violations during this period, such as a 12-point penalty record. After meeting this requirement, you must also pass an exam to complete the process. From my friend's case, some people lack the patience to wait and drive recklessly, which only extends the waiting period and causes more delays. This system actually protects road safety and helps develop good habits. I recommend regularly checking for updates in traffic regulations and preparing exam materials in advance to avoid last-minute panic.

Hey, I've been through the downgrade thing. After my Class B2 was downgraded, I had to wait three years before I could upgrade it back. During this time, I had to drive carefully—no reckless speeding or drunk driving, otherwise the clock would reset. I used to be adventurous when I was younger, but you live and learn; now I'm wiser. When I signed up for the upgrade, they checked my driving record thoroughly—pretty strict. Overall, you gotta keep your cool during the long wait, and it's a good chance to hone your small car skills.

In my work at the driving school, I often encounter such inquiries. If your driver's license is downgraded from B2 to C1, according to current regulations, you must hold the lower-level license for at least three years and have no record of accumulating 12 penalty points during that period before you can upgrade back to B2. In practice, I recommend reviewing traffic rules early and not delaying exam registration, as queuing can take time. Based on my experience, most students pass on their first attempt after the waiting period, provided they've developed safe driving habits. Don't underestimate this cooling-off period—it genuinely helps reduce road risks.
