In the field of driving, many drivers holding c-driving permits have the idea of upgrading c-driving permits to b-driving permits for reasons of work needs or increased personal driving capability. The following is a detailed description of the specific process and requirements for upgrading from the c to b driver's licence。
First of all, let's find out the type of b driver's permit, which is divided into b1 and b2. B1 permits are valid for medium passenger vehicles (urban buses carrying more than 10 and less than 19 persons) and b2 permits for large trucks, including heavy, medium cargo vehicles; heavy, medium special purpose vehicles, etc。

The upgrade from the c1 permit to the b1 permit requires the following: a c1 driver's licence for more than three years without a record of 12 minutes in the last three crediting cycles prior to the application; a person aged over 21 years and under 50 years; a height greater than 150 cm; two naked or corrective visions greater than 5. 0 cm; no red green blind; two ears 50 cm from the acoustic fork to distinguish the direction of the acoustic source; a good thumb with three fingers and normal body and function of the finger per hand; a well-developed lower limb and not more than 5 cm in length; and a body with no motor function in the dry and neck。
The conditions for upgrading from the c1 to the b2 driver's licence are relatively easy. The age must be 20 years or older and under 50 years of age; the height must also be 150 cm or more; the requirements for sight, colour, hearing, upper limb, lower limb, torso and neck are consistent with the requirements of the driver's permit for promotion to b1. And there is no need to have a c1 driver's license for more than three years, like the upgrade of b1。
Once the corresponding conditions have been met, the promotion process will be as follows: first, registration at the required driving school, submission of relevant information, such as identity cards, driving permits, etc. A medical examination is then carried out and once the medical examination has been completed, the corresponding training is available. The training included theoretical learning and hands-on exercises. While theoretical learning is mainly about traffic regulations, safety, etc., hands-on exercises are about driving skills for the b-driving permit. The final examination is in subjects i (theory test), ii (field driving skills test) and iii (road driving skills and a safe and civilized driving commons test), all of which will be successful in upgrading the c-driving permit to b。
The following is a comparison of conditions for the upgrade of c1 to b1 and b2:
The age requirement for advanced type driving requires other physical conditions
C1 upgrade b1
The c1 driver's licence was in possession for more than three years and the last three consecutive score cycles prior to the application did not record 12 minutes
Over 21, under 50
More than 150 cm height; two naked or corrective visions greater than 5. 0 m log; no red green blind; 50 cm distance from the acoustic fork to distinguish the direction of the acoustic source from the two ears; good thumbs with three fingers per hand and normal motor functions for the limbs and fingers per hand; well-developed lower limbs with normal motor functions of not more than 5 cm duration; torso, no motor function in the neck
C1 upgrade b2
No specific driving age requirement
20+, under 50
In any event, in order to upgrade the c driver's licence to a b driver's licence, the owner needs to confirm that he meets the corresponding conditions and then proceed with the required procedure. This will make it possible to successfully complete the upgrading of the driver's permit and to open up a wider field of driving。
