What vehicles can be driven after B2 is downgraded to C1M?

[DiTucker]

b2 downgraded to c1m can drive small cars, low-speed trucks, three-wheeled vehicles and wheeled self-propelled machinery. C1M has one more wheeled self-propelled machinery than C1. Wheeled self-propelled machinery is divided into rail wheeled self-propelled machinery and ordinary wheeled self-propelled machinery (including tire type and wheel hub type). The following are three situations where the B2 driver's license will be downgraded: 1. It will be downgraded if you get 12 points in a scoring cycle. 2. It will be downgraded if you fail to participate in the annual review for three consecutive scoring cycles. 3. If you do not renew your license for more than one year after the expiration date, your license will be downgraded and revoked.
