1How many questions are on the official Bulgaria Category D theory test under Ordinance No. 38, Art. 41?
A.10 questions
B.32 questions
C.20 questions
D.15 questions
Explanation: Ordinance No. 38, Art. 41 sets the Category D and D1 theory papers at 15 computer-based questions. Thirty-two is the maximum point total, not the item count. A short paper with a high pass mark is the official D format.
2What is the maximum number of points available on the Bulgaria Category D theory test?
A.15 points
B.28 points
C.32 points
D.35 points
Explanation: Ordinance No. 38, Art. 41 gives Category D and D1 a maximum of 32 points. Items are weighted (commonly 2 or 3 points), so the point total is not the same as the 15-question count. Category C1 uses a different 35-point scale.
3What score is required to pass the Bulgaria Category D theory test?
A.At least 15 of 32 points
B.At least 24 of 32 points
C.At least 28 of 32 points
D.At least 30 of 35 points
Explanation: A D or D1 candidate must score at least 28 of 32 points. That is a high threshold on a 15-question paper. The 30-of-35 figure belongs to Category C1, not bus theory.
4How much time does Ordinance No. 38 allow for the Category D theory test?
A.15 minutes
B.45 minutes
C.30 minutes
D.20 minutes
Explanation: Candidates have 20 minutes to complete the 15-question D/D1 theory test. Combined with the 28-of-32 pass mark, the paper is short and unforgiving. There is no published break in that sitting.
5Which statement about the official D and D1 theory papers is correct?
A.Category D and D1 both use 15 questions, 32 points, and a 28-point pass mark.
B.Only Category D uses 15 questions; D1 uses 20.
C.Category D1 is scored out of 35 points like Category C1.
D.Category D has no time limit; D1 is limited to 20 minutes.
Explanation: Ordinance No. 38, Art. 41 applies the same 15-question, 32-point, 28-to-pass, 20-minute rules to both D and D1. The vehicle definitions differ, but the theory-paper logistics do not.
6Which body administers Bulgaria’s Category D driving-licence theory test?
A.The Ministry of Interior traffic police only
B.The International Road Transport Union (IRU)
C.The municipal council of the candidate’s residence
D.The Executive Agency Road Transport Administration (ИААА)
Explanation: The Executive Agency Road Transport Administration (ИААА / IAAA) runs the computer-based licence theory tests, including Category D. IRU star categorisation is a touring-coach classification, not the exam body.
7How does the Category D theory test relate to Code 95 professional qualification?
A.Passing Category D theory automatically issues Code 95.
B.Ordinance No. 38 and Ordinance No. 41 are the same sitting.
C.Code 95 replaces the Category D theory test for all bus drivers.
D.Code 95 is a separate initial-qualification exam under Ordinance No. 41.
Explanation: Category D theory is the licence-knowledge test under Ordinance No. 38. Initial professional qualification (Code 95) is a different exam under Ordinance No. 41. Professional passenger work needs both the D licence path and the Code 95 qualification path.
8A Category D candidate scores 27 of 32 points in 20 minutes. What is the result?
A.Pass, because more than 80% of the points were earned
B.Pass, because 27 exceeds the Category C1 pass mark
C.Fail, because Ordinance No. 38 requires at least 28 of 32 points
D.The examiner may round 27 up to 28 at discretion
Explanation: The D/D1 pass mark is a hard 28 of 32. Twenty-seven is a fail even though it is a high percentage. There is no rounding or examiner discretion in the published Art. 41 rule.
9Under Road Traffic Act Art. 150a, a Category D vehicle is designed to carry:
A.More than 8 passengers plus the driver
B.Up to 8 passengers plus the driver
C.Goods only, with no passenger seats
D.Not more than 8 passengers excluding the driver
Explanation: Art. 150a defines Category D as motor vehicles designed to carry more than eight passengers plus the driver. That is the legal bus category. Up to eight passengers plus the driver is not Category D.
10In the IAAA Category D bank, vehicles of Category D are automobiles for passenger transport which, excluding the driver’s seat, have not fewer than how many seating positions?
A.8 seating positions
B.16 seating positions
C.12 seating positions
D.9 seating positions
Explanation: The official D theme states Category D vehicles have not fewer than nine seating positions excluding the driver. Eight is a listed distractor. Nine passenger seats matches Art. 150a’s “more than eight passengers plus the driver.”

About the Bulgaria Theory Test D Exam

Bulgaria's Category D theory test is the computer-based knowledge exam for buses designed to carry more than 8 passengers plus the driver. Ordinance No. 38 Art. 41 sets 15 questions, a 32-point maximum, a 28-point pass mark, and 20 minutes. IAAA publishes five Category D themes covering passenger-transport rules and documents, transport schemes and bus services, contracts, vehicle requirements, and passenger-accident measures. Road Traffic Act Art. 21 sets Category D speed limits at 50/80/100 km/h. Professional passenger work also requires the separate Code 95 initial-qualification exam under Ordinance No. 41.

Bulgaria Theory Test D: Suggested Study Strategy

1Memorise the D format: 15 questions, 32 points, 28 to pass, 20 minutes — a short, high-threshold paper.
2Use the current D table 50/80/100/100. After DV No. 64/2025, D is no longer grouped with C: C/CE motorway is 90 km/h, D remains 100.
3Know which documents a bus driver must carry on Community-licence versus non-EU international work.
4Study specialised transport of children: age, experience, and hours-of-operation rules in the official Category D bank.
5Passenger-accident insurance covers passengers, not the driver or crew — a frequent official-theme distinction.
