[DelGemma]

The differences between medium-sized buses and large buses are as follows: 1. Passenger capacity: Vehicles with a seating capacity of more than 9 but fewer than 20 people are classified as medium-sized passenger vehicles; those with a certified capacity of more than 19 people are classified as large buses. 2. Driver's license level: A Class A1 license is required to drive large buses; according to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' drivers holding a Class B1 license are permitted to operate medium-sized passenger vehicles. 3. Vehicle length: Vehicles shorter than 6 meters are classified as medium-sized passenger vehicles; large urban buses (10-12 meters) and extra-large urban buses (articulated buses are 13-18 meters, double-decker buses are 10-12 meters with two levels of seating).
