Category D Passenger-Vehicle Scope

Vietnam 2025 licence-category guidance

Category D is Vietnam's large passenger-vehicle GPLX category for vehicles with more than 29 seats excluding the driver, sleeper coaches, and lower listed passenger and goods categories. The 2025 CSGT guidance uses a 45-question theory test drawn from the official 600-question bank, with 16 road-sign questions and 14 sa-hinh traffic-situation questions as the largest sections. One serious unsafe-traffic question appears in every test set and a wrong answer on that item fails the theory test. The reviewed official sources did not publish a pass threshold, time limit, exam fee, or pass rate for this page.

1Under Vietnam's 2025 driver licence categories, which vehicles are in Category D?

A.Only motorcycles with engines over 125 cm3

B.Passenger vehicles with more than 29 seats, excluding the driver

C.Only goods vehicles over 7,500 kg

D.Only passenger vehicles with 10 to 16 seats

Explanation: Category D covers passenger vehicles with more than 29 seats, excluding the driver. It is the large bus category and is broader than smaller passenger categories.

2Which vehicle type is specifically included in Vietnam Category D?

A.Only electric bicycles

B.Only three-wheeled motorcycles

C.Sleeper coaches

D.Only passenger cars with up to 8 seats

Explanation: The 2025 category description includes sleeper coaches in Category D. This matters because sleeper coach drivers must manage passenger safety, fatigue risk, and emergency exits for long-distance service.

3What lower vehicle categories are included in the driving scope of Category D?

A.Lower passenger and goods categories such as B, C1, C, D1, and D2

B.Only motorcycles and mopeds

C.Only Category D1 vehicles

D.No lower categories are included

Explanation: Vietnam's 2025 category description lists Category D as including vehicles in lower passenger and goods categories. A Category D driver still needs to apply the rules for smaller vehicles safely.

4How many questions are on the official D1, D2, and D theory test set described by CSGT's 2025 guidance?

A.25 questions

B.30 questions

C.40 questions

D.45 questions

Explanation: CSGT's 2025 guidance says D1, D2, D, and several trailer-linked categories use a 45-question theory test. The questions are selected from the official 600-question bank.

5What happens if a candidate answers the serious unsafe-traffic question incorrectly?

A.The theory test is not passed

B.Only one ordinary point is lost

C.The candidate may replace the question

D.The answer is ignored if the total score is high

Explanation: CSGT guidance says every theory test includes one serious unsafe-traffic question. A wrong answer on that question is a fail condition for the theory test.

6How large is the official question bank used for Category D theory testing?

A.250 questions

B.300 questions

C.600 questions

D.1,000 questions

Explanation: Category D uses the full official 600-question bank. The D test selects a 45-question set from that bank, including one serious unsafe-traffic item.

7Which body issued the 2025 guidance on using the 600-question driving theory bank?

A.A private driving school association

B.The Traffic Police Department (CSGT) under the Ministry of Public Security

C.A bus ticketing company

D.A vehicle manufacturer

Explanation: The 2025 guidance was issued by the Traffic Police Department, known as CSGT, under the Ministry of Public Security. The guidance tells provincial police and testing centers how to use the bank.

8What does a no-entry sign require a Category D bus driver to do?

A.Do not enter that road or lane

B.Enter only if the bus is empty

C.Enter slowly while sounding the horn

D.Use the road only at night

Explanation: A no-entry sign prohibits entry by vehicles. A large passenger vehicle must obey it because backing out or turning around later can create a severe hazard.

9What is the basic action required at a stop sign?

A.Slow only if another vehicle is visible

B.Continue if the bus is on a priority route

C.Stop completely and proceed only when safe

D.Stop only when carrying passengers

Explanation: A stop sign requires a complete stop. The driver must then check for pedestrians, cyclists, and cross traffic before moving a large bus.

10What should a driver do at a yield sign?

A.Accelerate to clear the junction first

B.Stop for a fixed one-minute period

C.Ignore it if driving a passenger bus

D.Slow or stop as needed and give way

Explanation: A yield sign means the driver must give way to traffic or pedestrians with priority. Stopping is required when slowing alone is not enough to avoid conflict.

About the Vietnam GPLX D Exam

The Vietnam GPLX Category D theory test is the large passenger-vehicle driver-licence theory test for passenger vehicles with more than 29 seats, excluding the driver, and sleeper coaches. Vietnam's 2025 driver-licence categories also place lower listed passenger and goods categories within the Category D driving scope. CSGT's 2025 guidance says D1, D2, D and related trailer-linked categories use a 45-question theory set drawn from the official 600-question bank. Each set contains one serious unsafe-traffic question; answering that item incorrectly means the theory test does not meet requirements. The official topic mix covers general traffic rules, serious unsafe situations, traffic culture and driver ethics with fire/rescue awareness, driving technique, construction and repair, road signs, and sa-hinh traffic-situation handling.

Assessment

CSGT's 2025 guidance lists a 45-question theory set for D1, D2, D, BE, C1E, CE, D1E, D2E and DE: 10 general traffic-rule questions, 1 serious unsafe-traffic question, 1 culture/ethics/fire-rescue question, 2 driving-technique questions, 1 construction/repair question, 16 road-sign questions and 14 sa-hinh traffic-situation questions.

Vietnam GPLX D Study Tips from Top Performers

1Start with the official D structure: 16 road-sign questions and 14 sa-hinh traffic-situation questions make up two thirds of the 45-question set.

2Treat the serious unsafe-traffic question as a must-pass topic. Practise railway crossings, wrong-way or illegal reversing scenarios, flooding, brake failure, and pedestrian conflicts until the safe response is automatic.

3Study Category D as a passenger-safety exam, not only a signs exam. Include boarding, doors, luggage, emergency exits, evacuation, passenger conflict, medical emergencies, and sleeper-coach fatigue.

4For large-vehicle scenarios, prefer answers that slow early, increase space, check mirrors and blind spots, signal clearly, and avoid sudden braking or steering that could injure passengers.

5Do not memorize a passing threshold from unofficial sources for this page. The reviewed official sources used here did not publish one; focus on answering every serious unsafe-traffic item correctly and mastering the published topic mix.

Does the reviewed official guidance publish a pass threshold, time limit, or fee?

The reviewed official sources for this page publish the Category D vehicle scope, 45-question test structure, 600-question bank, and serious-question fail rule. They do not publish a Category D pass threshold, time limit, or exam fee in the cited materials, so this page does not invent those values.
