In the field of driving, the upgrade from c to b permits gives the driver wider driving rights and more types of vehicles. The following is an introduction to the approach and the corresponding requirements for the promotion of c-certificate b。
The first is to increase the b1 driver's license. The b1 driver's permit is a medium-sized passenger vehicle (including urban buses carrying more than 10 and less than 19 persons). The following conditions must be met in order to increase driving through this route: first, the age of over 21 years and the age of under 60 years; the c1, c2, c3 and c4 permits have been obtained for more than three years, and no record of 12 minutes has been recorded during the last three consecutive score periods prior to the application; and, in addition, physical conditions must meet the requirements, such as two naked eyes or corrective visions of 5. 0 or above, no red or green blind, and two ears 50 cm from the sound fork to distinguish the direction of the acoustic sources。

The second route is to increase the b2 driver's license. B2 driver's licence is valid for heavy, medium cargo vehicles; heavy, medium special purpose vehicles. If this is to be done, the person must be over 20 years of age and under 60 years of age; the person may apply directly for, or after obtaining a c1, c2, c3 and c4-a-driving permit, without a record of 12 minutes in the last score period prior to the application; the person's condition is similar to that of driving b1。
In order to compare more clearly the requirements of the two additional paths, the following is a detailed table:
The age of additional driver requires a driver's license to score the cycle
B1
21 - 60 years
C1, c2, c3, c4 license for more than three years
The last three consecutive score cycles prior to application did not record 12 minutes
B2
20 - 60 years
Can apply directly or obtain a c1, c2, c3, c4 license
There was no record of 12 points in the last score cycle before the application
Whether the b1 or b2 driver's license is selected, the corresponding examination is required for subjects i (theory knowledge), ii (field driving skills) and iii (road driving skills and safe and civilized driving commons). The content of the examinations will vary depending on the type of car to be driven. In preparing for the additional driver, the driver must be informed in advance and adequately prepared to successfully pass the examination and obtain a higher level of driver's permit。
