1According to the Provisions on the Application for and Use of Motor Vehicle Driving Licenses (MPS Order No. 162), which types of vehicles is a holder of an A1 driving license legally permitted to drive?
A.Large passenger vehicles (length >= 6m or seating capacity >= 20 persons), as well as vehicle classes A3, B1, B2, C1, C2, C3, C4, and M
B.Only large passenger vehicles with seating capacity exceeding 30 persons, excluding city buses and medium buses
C.Large passenger vehicles and heavy articulated semi-trailers (A2), but excluding light passenger vehicles (C1)
D.City buses and medium passenger vehicles only, excluding any freight vehicles or three-wheeled vehicles
Explanation: Under MPS Order No. 162, an A1 license authorizes the holder to drive large passenger vehicles (大型客车, defined as vehicles with a body length of 6 meters or more, or a passenger capacity of 20 or more persons). In addition, an A1 license includes driving privileges for city buses (A3), medium passenger vehicles (B1), heavy freight trucks (B2), small passenger cars (C1), small automatic cars (C2), low-speed freight trucks (C3), three-wheeled motor vehicles (C4), and wheeled self-propelled machinery (M).
2Under MPS Order No. 162, what is the defined scope of vehicles permitted to be driven under a Class A3 driving license (城市公交车)?
A.Intercity long-distance sleeper coaches and express highway touring buses with more than 30 passenger seats
B.Large passenger vehicles designed for urban public transit routes with a passenger capacity of 10 or more persons, as well as C1, C2, C3, and C4 vehicles
C.All heavy freight trucks (B2) and articulated tractor-trailers (A2) used for urban logistics
D.Medium passenger vehicles on interprovincial routes and specialized hazardous goods tankers
Explanation: Under MPS Order No. 162, a Class A3 driving license authorizes the holder to operate city buses (城市公交车, defined as passenger vehicles with a seating capacity of 10 or more persons designed for urban public transport). It also permits driving small motor vehicles (C1), small automatic vehicles (C2), low-speed freight trucks (C3), and three-wheeled motor vehicles (C4). It does not permit driving intercity large passenger coaches (A1) or medium intercity passenger vehicles (B1).
3Which of the following vehicle specifications defines a Medium Passenger Vehicle (中型客车) requiring a Class B1 driving license?
A.Body length of 6 meters or more and passenger seating capacity exceeding 20 persons
B.Body length less than 4 meters and seating capacity of up to 9 persons
C.Body length less than 6 meters and passenger seating capacity of 10 to 19 persons
D.Articulated passenger vehicles with length exceeding 12 meters operating on dedicated routes
Explanation: Under national standards (GA 802 and GB 7258-2017) and MPS Order No. 162, a Medium Passenger Vehicle (中型客车, B1) is defined as a passenger vehicle with a body length of less than 6 meters and a passenger seating capacity of 10 to 19 persons (inclusive). Vehicles with 20 or more seats or body length >= 6m are classified as large passenger vehicles (A1).
4Under MPS Order No. 162, what are the statutory age requirements for an applicant applying for a Class A1 (Large Passenger Vehicle) driving license?
A.At least 18 years of age and not more than 70 years of age
B.At least 26 years of age and not more than 50 years of age with no vocational exceptions
C.At least 24 years of age and not more than 65 years of age
D.At least 22 years of age and not more than 63 years of age (or at least 19 years of age for students in certified full-time driver vocational education)
Explanation: Article 14 sets the Class A1 bracket at 22 and above but under 63, with a special lower entry of 19 for students receiving full-time vocational driving education. Both figures are recent: MPS Order 162 cut the minimum from 26 to 22 and raised the ceiling from 50 to 60 in 2022, and MPS Order 172 raised the ceiling again from 60 to 63 with effect from 1 January 2025.
5An applicant holding a Class B1 (Medium Passenger) or B2 (Heavy Truck) license wishes to upgrade (增驾) to a Class A1 (Large Passenger) license. What is the minimum license holding period and scoring cycle requirement under MPS Order No. 162?
A.B1 for at least 2 years, or B2 for at least 3 years, with no record of reaching 12 penalty points in the 3 most recent consecutive scoring cycles
B.Either licence for at least 1 year, with no more than 6 penalty points in the current cycle
C.Either licence for at least 5 years, with zero total penalty points across the entire period
D.Either licence for at least 3 years, with no traffic accidents of any kind
Explanation: Article 17(4) sets a different qualifying period for each feeder category rather than a single figure: two years of 城市公交车 (A3) or 中型客车 (B1) qualification, three years of 大型货车 (B2) qualification, or one year of 重型牵引挂车 (A2) qualification. On top of that the applicant must have no record of reaching 12 points in any of the three most recent consecutive scoring cycles. The B2 route was shortened from five years to three by MPS Order 162 in 2022.
6Under MPS Order No. 162, which of the following represents the statutory upgrade path to apply for a Class B1 (Medium Passenger Vehicle) driving license?
A.Must have held a C1 license for at least 1 year with zero traffic violations
B.Must have held a C1, C2, C3, C4, A3, or B2 license for at least 2 years, with no record of accumulating 12 penalty points in the 2 most recent consecutive scoring cycles
C.Direct initial application is permitted from age 18 without holding any prior driving license
D.Must have held an A1 license previously and voluntarily requested a downgrade
Explanation: Article 16 excludes 中型客车 from the categories that can be applied for as a first licence, and Article 17(2) sets the upgrade route: two years or more of 城市公交车 (A3), 大型货车 (B2), 小型汽车 (C1), 小型自动挡汽车 (C2), 低速载货汽车 (C3) or 三轮汽车 (C4) qualification, with no record of reaching 12 points in the two most recent consecutive scoring cycles. Note the cycle count differs by target category — B1 looks back two cycles, whereas A1 looks back three.
7Under Article 15 of MPS Order No. 162, which of the following circumstances permanently disqualifies an applicant from applying for or upgrading to an A1, A3, or B1 passenger driving license?
A.Having accumulated 6 penalty points for speeding on an ordinary road within the past year
B.Having failed the Subject 1 computer theory test on the initial attempt
C.Having caused a major traffic accident resulting in human death with equal or greater responsibility (同等以上责任)
D.Having received an administrative parking ticket on an urban side street
Explanation: Under MPS Order No. 162, an applicant is permanently disqualified from applying for or upgrading to large or medium passenger vehicle licenses (A1, A2, A3, B1) if they have caused a fatal traffic accident bearing equal or greater responsibility, or have a record of drunk driving or driving commercial vehicles after drinking.
8According to MPS Order No. 162, when must a driver holding an A1, A3, or B1 passenger vehicle driving license undergo the mandatory annual license verification (审验)?
A.Every 6 months regardless of whether penalty points were recorded
B.Only once every 6 years upon the expiration and renewal of the driving license
C.Immediately within 24 hours of receiving any single traffic ticket
D.Within 30 days after the end of the scoring cycle if any penalty points were accumulated during that cycle
Explanation: Under Article 72 of MPS Order No. 162, holders of large/medium passenger and freight driving licenses (A1, A2, A3, B1, B2) must undergo annual verification (审验) within 30 days after the end of each scoring cycle if they have accumulated penalty points during that cycle. During verification, they must complete at least 3 hours of traffic safety education.
9If an A1 or A3 passenger bus driver accumulates zero penalty points throughout an entire 12-month scoring cycle, what is the annual verification requirement for that cycle?
A.The driver is exempt from the annual verification (审验) for that specific scoring cycle
B.The driver must still attend 3 hours of classroom safety lectures at the vehicle administration office
C.The driver must retake the Subject 1 computer theory test
D.The driver must submit an extensive vehicle mechanical inspection log
Explanation: Under Article 72 of MPS Order No. 162, if an A1, A2, A3, B1, or B2 license holder has no recorded penalty points (0 points) in a scoring cycle, they are exempt from annual verification (免予本记分周期审验) for that cycle.
10Under Article 65 of the driving-licence Provisions as amended by MPS Order 172, what happens to a commercial passenger bus driver on reaching the statutory upper age for large and medium passenger vehicles?
A.At 63 they may apply, in the preceding year, to extend the category for up to three more years after passing memory, judgement and reaction tests; otherwise they exchange the A1/A3/B1 licence for Class C1 or C2 within 30 days
B.At 60 they must exchange the A1/A3/B1 licence for a Class C1 or C2 licence within 30 days, with no possibility of extension
C.Their driving licence is cancelled outright and they may no longer drive any motor vehicle
D.They may keep the licence but are restricted to long-distance sleeper coach routes only
Explanation: MPS Order 172, in force from 1 January 2025, raised the Article 65 cut-off from 60 to 63 and introduced an extension route that did not exist before. A driver aged 63 or over may not drive 大型客车, 重型牵引挂车, 城市公交车, 中型客车 or 大型货车 and is given 30 days to exchange the licence for Class C1 or C2. But in the year before turning 63 the driver may apply to continue in the existing category after passing tests of memory, judgement and reaction, for a maximum extension of three years.

China Driving Subject 1 (Bus) Study Tips from Top Performers

1Memorize statutory speed limits: remember that large and medium passenger buses are strictly capped at 100 km/h on expressways regardless of a higher posted limit for small cars.
2Understand the inner wheel difference (内轮差): when a long bus turns, the rear inner wheel tracks significantly inside the path of the front wheel, creating a hazardous blind zone for pedestrians and cyclists.
3Know safety equipment functions: pneumatic door interlocks prevent door opening at speeds > 5 km/h; emergency manual release valves vent air pressure so doors can be pushed open during electrical power failure.
4Master MPS Order 163 penalty points: driving a commercial passenger vehicle overloaded by >= 20%, speeding by >= 20% on expressways, or driving while intoxicated triggers an immediate 12-point deduction.
5Review adverse weather speed rules on expressways: visibility < 200m -> 60 km/h; visibility < 100m -> 40 km/h; visibility < 50m -> 20 km/h with mandatory immediate exit.

Frequently Asked Questions

What is the China Driving Subject 1 (科目一) Exam for passenger vehicles?

Subject 1 is the mandatory computer-based theoretical examination on road traffic safety laws, regulations, passenger vehicle licensing, road markings, and safe driving fundamentals required to obtain an A1 (large bus), A3 (city bus), or B1 (medium bus) commercial driving license in China.

What are the age requirements for A1, A3, and B1 passenger driving licenses in China?

Article 14 of the Provisions sets a minimum of 20 for A3 (city bus) and B1 (medium bus), and 22 for A1 (large bus) — or 19 for students in full-time vocational driving education. The upper limit for all three is 63, raised from 60 by MPS Order 172 with effect from 1 January 2025. At 63 the commercial passenger entitlement lapses and the licence is exchanged for C1 or C2, unless the driver applied in the preceding year to extend it by up to three years after passing memory, judgement and reaction tests.

What is the maximum speed limit for large and medium passenger buses on Chinese expressways?

Under Article 78 of the Implementation Regulations of the Road Traffic Safety Law, the maximum speed limit for medium and large passenger vehicles (buses and coaches) on expressways is strictly capped at 100 km/h, even on road sections where small passenger cars are permitted to drive up to 120 km/h.

What are the continuous driving and fatigue limits for commercial bus drivers?

Drivers of passenger vehicles must not drive continuously for more than 4 hours without stopping for rest. Each rest period must last at least 20 minutes. Total driving time within any 24-hour period must not exceed 8 hours. Driving medium or large passenger vehicles continuously for over 4 hours without adequate rest incurs a 9-point deduction under MPS Order 163.

What are the night driving restrictions for intercity long-distance passenger coaches?

Under joint Ministry of Transport and Ministry of Public Security safety regulations, long-distance passenger coaches and sleeper buses are prohibited from operating on expressways and highways between 02:00 and 05:00, or must implement a strict relay driving system where drivers rotate at scheduled intervals and stop at designated service areas.

What is the penalty for driving a commercial passenger vehicle after consuming alcohol in China?

Under Article 91 of the Road Traffic Safety Law, drinking and driving a commercial motor vehicle (营运机动车) results in 15 days of administrative detention, a fine of RMB 5,000, revocation of the driving license, and a 5-year bar from reapplying. Drunk driving (BAC >= 80 mg/100 mL) commercial vehicles incurs criminal liability, license revocation, and a 10-year bar from driving commercial vehicles.
