C6 driver's license is required for driving light trailer. For drivers who already hold driver's licenses for driving approved models of large buses, city buses, medium-sized buses, large trucks, small cars or small automatic transmission vehicles, if they want to apply for adding approved models of light tractor trailers, they only need to add the corresponding light tractor trailer subject II examination. Precautions: 1. It is known that we only have 12 points in a cycle of our driving license, and we will be fined for points deduction when we drive a car in violation of regulations. When we have 12 points deducted in a cycle of our driving license, we will no longer be able to drive a car in this cycle, and we need to meet this condition when we drive a C6 driving license, The driver's license cannot be deducted 12 points in the previous cycle of additional driving. If the driver's license is deducted 12 points, he or she will not be able to take the additional driving registration test. 2. Each driver license at the age of 20-60 has a corresponding age for examination. The age limit before C1 and C2 driver licenses is 18-70 years old. However, with the improvement of people's living standards and medical standards, the average life span of people is increasing, thus abolishing the maximum age limit. You can take the test as long as you pass the physical examination, but the age limit of the C6 driver license is 20-60 years old. If you do not meet this age group, you will not be able to take the test or upgrade.
