To apply for adding a tractor driving license category, you must have held a medium-sized bus or large truck driving license for at least three years, or a large bus driving license for at least one year, and have no record of accumulating 12 penalty points in the last three consecutive scoring cycles before the application.

Adding a driving license category refers to expanding your existing driving privileges. Those who have just obtained a driving license (such as a motorcycle license) can only apply for other types of driving licenses after one year. During the application and examination process for adding a category, you must bring your ID card and the previously obtained driving license. Those who pass the exam will be granted the additional category. To add a driving license category, you must have a local household registration in the area where the original license was issued, and the issuing authority of the license must also be local. If you do not meet these requirements, the application will not be processed, and you must transfer the license relationship.

The conditions for adding a driver's license mainly include age requirements, the current type of driver's license held, and the duration of holding it. For example, to add a motorcycle license, you must have held a C1 license for at least one year, be at least 18 years old, and not have accumulated 12 penalty points in the last two scoring cycles. A medical examination is also mandatory, and you must not have color blindness or color weakness. The requirements vary for different vehicle types. For instance, to add a large truck license, you must be at least 20 years old and have held a B1 license for at least two years. In short, you must meet the basic conditions for the intended vehicle type before you can take the new subject exams.

If you plan to upgrade your driver's license, the first step is to check the type and duration of your current license. For example, to ride a motorcycle, you must have held a Class C license for at least one year, be at least 18 years old, and have no record of accumulating 12 penalty points in the last two scoring cycles. Additionally, the medical examination is crucial, especially the vision test, which must meet the requirements. It's best to visit the local DMV to clarify the specific requirements, as the difficulty varies significantly for different vehicle types. For instance, the conditions for upgrading to a bus or coach license are very strict, requiring not only a certain duration of driving experience but also a clean record with no serious accidents.

The requirements for adding a driving license vary depending on the vehicle type but share common points: you must hold a valid driver's license and meet the minimum driving experience required for the corresponding vehicle type. For example, adding a motorcycle license requires holding a C1 license for at least one year. Physical conditions are equally important, including meeting vision and hearing requirements. Special attention should be paid to violation records, such as drunk driving records, which can affect eligibility. Requirements may vary slightly in different regions, so it is advisable to consult the local traffic management department for the most accurate information. After obtaining the new driver's license, it is also important to pay attention to the management regulations during the probationary period.

The most crucial factors for upgrading a driver's license are age, the duration of holding the current license, and traffic violation records. For example, to upgrade to a large bus license, one must be at least 22 years old and have held a B1 license for more than three years. There should be no full-point records in the last two scoring cycles. Additionally, all license upgrades require passing a physical examination, especially the color vision test, which must not indicate color blindness. Some special vehicle types also require a record free of major accident liabilities. It is important to remind everyone to ensure that the original driver's license is in normal status before applying for an upgrade, as any pending traffic violations will prevent the process.
