Dazu district takes an examination of the qualification certificate of southwest training center network car. The location is near the new station. In addition to the qualification certificate (road passenger transport qualification certificate), there are also taxi driver qualification certificate, professional qualification certificate, taxi employee security registration certificate, bus driver rotation training certificate, taxi driver security prevention skills training certificate, and motor vehicle driver health rescue training certificate. If it's a gas car, it's ok to have a cng driver training certificate, but you can only take the road freight transport test, and you can only take the test after three years of road passenger transport. These are all tested in the Southwest Training Center.
