With the continuous improvement of the development level of domestic logistics and transportation industry, various types of semi trailers can be seen everywhere on today's high-speed. In the past, if you want to drive a truck to transport goods, you need to apply for a class B2 driver's license. Do you also need a class B2 driver's license to drive a semi-trailer?

The answer is No. Different from ordinary trucks, semi trailers belong to tractors and need to hold class A2 driver's license to drive on the road. Therefore, if the truck owner wants to replace the semi-trailer, he needs to apply for additional driving in advance.

The permitted driving models of A2 driver's license mainly include: Tractor (including semi-trailer and full trailer), medium-sized bus, large truck, small manual transmission vehicle, small automatic transmission vehicle, low-speed truck, three wheeled vehicle and wheeled self-propelled mechanical vehicle.

The registration conditions for A2 driver's license are as follows:

1. Age: 24-50 years old;

2. Additional driving requirements: hold B1 or B2 driver's license for 3 years or more, or A1 driver's license for 1 year or more, and there is no full score record in the last three consecutive scoring cycles before application.

After getting the corresponding driver's license, does it mean that you can drive? That's easy to think about, because in addition to the driver's license, driving a semi-trailer for transportation also needs to prepare various certificates, such as:

1. Driver's license.

If the driver's license is the driver's certificate, then the driving license is the vehicle's certificate; Without a driver's license, the driver can't drive. Without a driving license, the vehicle can't go on the road normally. Drivers must hold both driver's license and driving license before they can legally go on the road.

The full name of the driving license is the motor vehicle driving license, which is the legal certificate that allows the motor vehicle to drive on the roads in China. It records the license plate number, vehicle type, owner's name, address, vehicle brand type, nature of use, technical data of the vehicle leaving the factory and the issuing date of the certificate.

2. Road transportation operation license.

The operation certificate is the legal certificate of vehicles engaged in road transportation business activities. If there is no operation certificate, it means that the owner belongs to unlicensed operation, which is often referred to as "black car".

The operation certificate is issued to the owner and generally does not need to be carried with the vehicle.

3. Road Transport Certificate.

Road Transport Certificate is a valid certificate for the legal operation of vehicles. It is also the main certificate to record the examination of operating vehicles and reward and punishment to operators. Generally, the road transport license can only be issued after the operation license is issued, and the road transport license must be carried with the vehicle and can pass through the country within the validity period.

The road transport certificate needs to be verified once a year, which is what we often call annual examination.

4. Road transportation qualification certificate.

This is a kind of certificate issued after passing the examination of road transportation related knowledge and skills of the transportation department. Many car owners believe that the existence of professional qualification certificate is superfluous. They have obtained their driver's license. Why do they need professional qualification certificate?

For this problem, we also need to analyze the specific situation. For example, for those transportation types with high requirements for vehicle owners, such as the transportation of dangerous goods, the existence of professional qualification certificate is still very necessary. After all, this is also a threshold limit, which is convenient for the monitoring and management of traffic control departments.

In addition, in 2019, the Ministry of transport has cancelled the operation certificate and professional qualification certificate of ordinary freight vehicles with less than 4.5t, and adopted appropriate simplification of administration and decentralization, which can reduce the owner's time, energy and economic cost to a certain extent.

5. Motor vehicle registration certificate.

The vehicle registration certificate is the legal proof of vehicle ownership, which is kept by the vehicle owner and does not need to be carried with the vehicle. This certificate is required for subsequent vehicle transfer and ownership transfer, which is equivalent to the "household register" of the vehicle.

6. Vehicle technical archives.

Vehicle technical archives refer to the historical archives that record the basic situation, main performance, operation and use of vehicles, replacement of main parts, inspection and maintenance records, accident handling and other relevant vehicle data during the whole operation process from the purchase of new vehicles to scrapping.

The vehicle ownership transfer procedures shall be completed when the vehicle is handed over. Vehicle technical files shall be used as the basis for issuing and reviewing operation certificates. For vehicles without archives or incomplete archives, the transportation management department shall not issue operation certificates.

7. Business license of individual industrial and commercial households

As for the business license of individual industrial and commercial households, I don't want to repeat it. In short, in the freight industry, if you want to be the master and make money in transportation, you need to apply for the business license of individual industrial and commercial households.

Is this string of certificates beginning to get confused? But these are only conventional certificates. In addition, there are unconventional certificates such as Beijing entry permit and out of gauge transportation permit. Some of them need to make great efforts if they want to do it.

It can be seen that driving a semi-trailer for transportation is not a simple thing. These various documents alone have made people hear a lot. There are also depressed freight, transportation reversed day and night, traveling all year round, some tricky cargo owners, and so on. In order to improve the operation efficiency in various cracks, the procurement of semi-trailer parts is a knowledge. How to select high-quality and affordable products from a wide variety of brands is very key to reducing the cost of comprehensive vehicles.

Take Darong axle, the representative of domestic high cost performance trailer axle, for example. In terms of performance, Darong axle adopts the advanced one-piece axle casting process, which grinds the axle body and axle head from a steel pipe. Compared with the traditional three-piece welded axle, Darong axle has stronger heavy load performance and better stability. In addition, Darong has enhanced the design of axle head, The thickness and strength of the bearing position are increased to provide higher guarantee for product performance. In terms of price: since Darong axle entered the market for more than 20 years, it has always insisted on facing the audience with real price. The current price of ordinary disc axle is about 6500 yuan and that of ordinary drum axle is about 3500 yuan, so that users can really spend less front and use higher quality axle.
