1How many questions does Ordinance No. 38, Art. 41 set for the IAAA computer-based theory test for categories C1E, CE, D1E and DE?
A.15 questions
B.30 questions, matching the Category C goods paper
C.40 questions, matching the Category A motorcycle paper
D.45 questions, matching the Category B car paper
Explanation: Ordinance No. 38 of 16 April 2004, Art. 41(1) states that theory tests for C1, D, D1, C1E, CE, D1E and DE each contain 15 questions. For the Category E combination papers (C1E, CE, D1E and DE) those 15 items are scored out of 29 points. Do not confuse this short combination paper with the longer Category B or C theory tests.
2What is the maximum number of points available on the IAAA theory test for categories C1E, CE, D1E and DE?
A.35 points, the same as the Category C1 paper
B.97 points, the same as the Category B car paper
C.32 points, the same as the Category D passenger paper
D.29 points
Explanation: Art. 41(1)(4) of Ordinance No. 38 sets a 29-point maximum for the C1E, CE, D1E and DE theory tests. Individual items carry different point values, which is why 15 questions total 29 rather than 15. Category D/D1 (32 points) and Category C1 (35 points) use different keys even though they also have 15 questions.
3What is the pass mark on the Bulgarian C1E, CE, D1E and DE theory tests?
A.A simple majority of the 15 questions, regardless of points
B.At least 20 of 29 points
C.At least 23 of 29 points
D.At least 26 of 29 points
Explanation: Ordinance No. 38, Art. 41(1)(4) requires at least 26 points from the 29-point maximum. Because items are weighted, answering 13 of 15 questions correctly does not automatically pass if the missed items were high-value. Candidates must think in points, not in a raw question count.
4How long does Ordinance No. 38 allow for the C1E, CE, D1E and DE theory test?
A.30 minutes, matching Category C
B.40 minutes, matching Category B
C.10 minutes
D.20 minutes
Explanation: Art. 41(2) of Ordinance No. 38 gives candidates 20 minutes to complete the 15-question C1E/CE/D1E/DE theory test. That is a tight timed paper: just over one minute per item, including the higher-value coupling and inspection questions. Category C is 30 minutes and Category B is 40 minutes.
5A candidate already holds Category B and applies only for Category BE. Which IAAA examination does Ordinance No. 38 require?
A.The same 15-question CE/DE theory paper, then a yard test
B.A separate 15-question BE theory paper worth 29 points
C.A practical examination only; there is no BE theory paper for a holder of B
D.The full Category B theory test again, because a trailer is attached
Explanation: Appendix 8 to Ordinance No. 38 (row for 'B with code 96 or BE, who hold Category B') marks a practical exam only. Art. 41 lists theory papers for C1E, CE, D1E and DE, not for BE. Holders of B who want BE therefore sit a yard-and-road coupling test, not a Category E theory paper. This English MCQ bank prepares the CE/DE theory paper, not the BE practical.
6Which body administers the computer-based Category E theory test in Bulgaria?
A.Municipal driving schools, which set and mark their own trailer papers
B.The European Commission, which issues a uniform EU Category E e-test
C.The Ministry of Interior traffic police (КАТ) as the sole examining authority
D.The Executive Agency Road Transport Administration (ИААА / IAAA)
Explanation: Ordinance No. 38 places theoretical examinations in the exam rooms of the Executive Agency Road Transport Administration (Изпълнителна агенция „Автомобилна администрация“, IAAA). Tests are generated and sat on IAAA computers under video surveillance. Traffic police enforce road rules but do not administer this licence-acquisition theory paper.
7Which statement correctly compares the IAAA theory papers for C1E, CE, D1E and DE?
A.Only CE has 15 questions; D1E and DE use the 30-question Category C paper
B.All four Category E combination papers use 15 questions, 29 maximum points, a 26-point pass and 20 minutes
C.D1E is practical-only, while CE and DE share a 40-minute 45-question paper
D.C1E is scored out of 35 points because it is grouped with Category C1
Explanation: Art. 41(1)(4) and Art. 41(2) apply the same 15-question, 29-point, 26-to-pass, 20-minute format to C1E, CE, D1E and DE. C1 itself is a different 15-question paper scored out of 35 with a 30-point pass. Do not mix the rigid-vehicle C1 key with the C1E trailer key.
8Why is this English practice bank not a substitute for a Category BE practical test?
A.Because Ordinance No. 38 treats BE, for a holder of B, as a practical-only upgrade with no theory paper
B.Because BE candidates sit the same 15-question CE theory paper, so extra practice is unnecessary
C.Because BE is issued automatically with every Category B licence in Bulgaria
D.Because IAAA no longer examines any trailer combination, including CE and DE
Explanation: Appendix 8 to Ordinance No. 38 requires only a practical exam for BE (or B with code 96) when the candidate already holds B. Coupling, reversing with a trailer, and load-security checks are assessed on a yard and on the road. This bank is an English four-option MCQ study adaptation of the CE/DE theory themes, not a BE coupling simulation and not an official translation of the IAAA item bank.
9When does a Category C goods vehicle towing a trailer generally require Category CE under Road Traffic Act Art. 150a?
A.Whenever the trailer has two or more axles, even if its mass is 500 kg
B.Whenever the trailer has no overrun brake, regardless of mass
C.Whenever the trailer's maximum permissible mass exceeds 750 kg
D.Whenever the journey is international, even with a 500 kg trailer
Explanation: Art. 150a(2)(11) defines CE as a combination of a Category C drawing vehicle and a trailer or semi-trailer with maximum permissible mass over 750 kg. A Category C vehicle may still form a combination with a trailer not exceeding 750 kg without CE. Axle count and journey type do not replace the 750 kg threshold.
10Which trailer may a Category B driver tow in Bulgaria without holding BE?
A.A semi-trailer of 10 t, because semi-trailers are excluded from E categories
B.Any trailer, provided the towing car has a factory towbar
C.Any caravan, because Category B always includes unlimited trailer rights
D.A trailer whose maximum permissible mass does not exceed 750 kg
Explanation: Art. 150a(2)(6) allows Category B motor vehicles to form a combination with a trailer of maximum permissible mass not exceeding 750 kg. A heavier trailer generally needs BE (capped at 3 500 kg for the trailer or semi-trailer) or, in a narrow B-code-96 case, a combination not exceeding 4 250 kg. A towbar is equipment, not a licence.

About the Bulgaria Theory Test E Exam

Bulgaria's Category E theory test is the computer-based knowledge exam for trailer combinations CE, DE, C1E and D1E. Ordinance No. 38 Art. 41 sets 15 questions, a 29-point maximum, a 26-point pass mark, and 20 minutes. IAAA publishes five Category E themes covering tractors, trailers, coupling systems, daily inspections, and combination safety. Road Traffic Act Art. 21 as amended by DV No. 64/2025 sets CE at 50/80/90/90 km/h and DE at 50/80/100/100 km/h. Category BE holders of B take a practical exam only. This bank is an English-language MCQ study adaptation, not an official translation and not a substitute for the practical coupling test.

Bulgaria Theory Test E Study Tips from Top Performers

1Memorise the CE/DE format: 15 questions, 29 points, 26 to pass, 20 minutes.
2Do not quote the repealed 50/70/100 combination row. CE follows C at 50/80/90/90; DE follows D at 50/80/100/100.
3Learn trailer versus semi-trailer: a semi-trailer transfers a substantial part of its weight onto the tractor.
4Daily inspection and coupling-system names are a large share of the official E bank.
5Do not treat this bank as BE practical-test practice; BE is a yard-and-road performance exam.
