1What is the minimum statutory age required to obtain a Category C (heavy goods vehicle) driving licence in Cameroon?
A.21 years
B.18 years
C.25 years
D.16 years
Explanation: The Cameroonian arrêté governing driving licences and driving schools sets the minimum age at 16 for Category A, 18 for Categories B, E and G, and 21 for Categories C, D, F and the special permits. Note that the CEMAC Community Code is not identical here — it sets 20 for Category C and 21 for D and E — so answer questions on age from the national text unless the question names the CEMAC code.
2What prior driving experience is legally required in Cameroon before an applicant can enroll for a Category C driving licence examination?
A.Must have held a valid Category B driving licence for at least 2 years
B.Must have held a Category A motorcycle licence for 1 year
C.No prior licence is required if the candidate passes a physical agility test
D.Must have worked as a mechanic's apprentice for 3 years
Explanation: The Cameroonian arrêté on driving licences requires a Category C candidate to show at least two years of effective driving on a Category B licence. The chain continues upward: Category D requires a year of effective driving on a Category C licence, and Category E requires two years on a Category C licence. A favourable medical certificate is required for all of them, and a criminal record extract less than three months old is additionally required for Category D.
3Outside built-up areas and absent any restrictive signing, what maximum speed does the CEMAC Highway Code set for a goods vehicle of between 3,500 kg and 12,500 kg PTAC, and for public passenger transport vehicles?
A.90 km/h
B.110 km/h
C.60 km/h
D.120 km/h
Explanation: Article 90 of the CEMAC code sets a graduated scale outside built-up areas: 110 km/h for motorcycles and vehicles up to 3,500 kg other than taxis and public transport; 90 km/h for vehicles between 3,500 and 12,500 kg and for all public passenger transport vehicles; 60 km/h above 12,500 kg, for any vehicle towing a trailer over 750 kg, and for convoys; and 50 km/h for all other machines.
4In a built-up area (en agglomération), what maximum speed does the CEMAC Highway Code set for a vehicle of more than 3,500 kg?
A.40 km/h
B.60 km/h
C.70 km/h
D.80 km/h
Explanation: Article 90 of the CEMAC code splits the built-up-area limit by weight: 60 km/h for vehicles under 3,500 kg, but only 40 km/h for vehicles over 3,500 kg. Cameroon's own road traffic decree is stricter still, capping heavy vehicles and mopeds at 30 km/h in built-up areas, so a heavy vehicle driver should treat 40 km/h as an absolute ceiling and expect lower local limits.
5What is the maximum load the CEMAC Highway Code permits on a single axle, as checked at weighbridge stations (stations de pesage) in Cameroon?
A.13 tonnes
B.10 tonnes
C.16 tonnes
D.20 tonnes
Explanation: Article 20 of the CEMAC code fixes the maximum axle load at 13 tonnes for a single axle, 21 tonnes for a tandem group and 27 tonnes for a tridem group, with the gross laden weight of the vehicle capped at 50 tonnes. Article 73 makes weighing compulsory for any vehicle over 3.5 tonnes on roads equipped with a weighing installation.
6What is the maximum permissible tandem axle group (deux essieux / tandem) weight limit under CEMAC transport regulations?
A.21 tonnes
B.13 tonnes
C.27 tonnes
D.32 tonnes
Explanation: Article 20 of the CEMAC code sets a flat figure of 21 tonnes for a tandem axle group, between the 13-tonne single-axle limit and the 27-tonne tridem limit. Distributing the load so that no axle or group exceeds these figures is expressly required by Article 21.
7What is the maximum overall width the CEMAC Highway Code authorises for a goods vehicle, load included?
A.2.50 metres
B.2.60 metres
C.3.00 metres
D.2.20 metres
Explanation: Article 22 of the CEMAC code fixes a single maximum width of 2.50 metres, measured over every projection except mirrors, marker lights and direction indicators. Anything wider is an exceptional transport requiring the authorisation issued under Article 85.
8What is the standard maximum authorized vehicle height for all commercial trucks and combinations in Cameroon?
A.4.00 metres
B.4.50 metres
C.3.50 metres
D.5.00 metres
Explanation: Under CEMAC and Cameroonian traffic regulations, the maximum overall height for any commercial motor vehicle or combination (including load) is 4.00 metres to ensure clearance under bridges, toll gates, and overhead electrical lines.
9What is the maximum overall length the CEMAC Highway Code authorises for an articulated vehicle (tracteur routier + semi-remorque)?
A.15.50 metres
B.16.50 metres
C.12.00 metres
D.18.00 metres
Explanation: Article 22 of the CEMAC code lists three maximum lengths, all measured over every projection: 12 metres for a rigid vehicle on its own, 15.50 metres for an articulated combination, and 18 metres for a drawbar road train.
10What is the maximum overall length permitted for a drawbar road train (camion porteur + remorque) under the CEMAC Highway Code?
A.18.00 metres
B.18.75 metres
C.15.50 metres
D.12.00 metres
Explanation: Article 22 of the CEMAC code caps a road train at 18 metres overall, projections included. Exceed it and the vehicle becomes an exceptional transport needing the single-journey authorisation issued under Article 85, which names the route and the precautions required.

About the Cameroon Heavy-Vehicle Theory Exam

The Cameroon driving theory test for Categories C, D and E is the written examination the Ministry of Transport sets before a professional candidate may take the practical test for a rigid goods vehicle over 3,500 kg (C), a vehicle carrying more than eight passengers besides the driver (D), or a combination pulling a trailer over 750 kg (E). Its subject matter is the CEMAC Community Highway Code as applied in Cameroon: axle limits of 13, 21 and 27 tonnes and a 50-tonne gross ceiling enforced at weighbridges, dimension limits of 2.50 m wide, 4 m high and 12, 15.50 or 18 m long, the speed scale that drops to 40 km/h in built-up areas and 90 or 60 km/h outside them by weight, the 50-metre gap that lets cars overtake, six-monthly technical inspection for goods vehicles and three-monthly for buses, rain barriers on earth roads, and the pneumatic braking, load securing and descent technique on which heavy-vehicle safety rests.

Assessment

A 40-question multiple-choice paper in two parts: Part A is 20 questions without images and Part B is 20 questions on the interpretation of images. Every question carries one mark and cancelling an answer costs a mark. The pass mark is an average of 12/20, that is 24 correct out of 40, and only candidates who pass the theory paper are admitted to the practical test. Heavy-vehicle candidates also face a searching oral check on the Highway Code and a probationary drive on a vehicle of the category applied for.

Cameroon Heavy-Vehicle Theory Study Tips from Top Performers

1Learn the speed scale by weight band rather than as one number: 40 km/h in a built-up area above 3,500 kg, then 90, 60 or 50 km/h outside one depending on weight and whether you are towing.
2Memorise the CEMAC dimension and weight figures exactly, because the European numbers are close enough to be tempting and wrong: 2.50 m wide with no refrigerated exception, 4 m high, 12 m rigid, 15.50 m articulated, 18 m road train, 13/21/27 tonnes by axle group, 50 tonnes gross.
3Master pneumatic braking as a system: the governor cuts the compressor in and out, the dryer keeps moisture out, daily draining keeps it from corroding valves, and if pressure falls too far the spring brakes apply themselves whether you want them or not.
4Get into low gear and engage the retarder before a descent begins, not after speed has built. Once the drums are hot enough to fade, no amount of pedal pressure brings the vehicle back.
5Read an orange hazard plate top down: the upper number is the Kemler hazard code, the lower is the four-digit UN substance number, and an X in front means water must not be used on it.
6Remember the two distances that catch heavy vehicle candidates out: 50 metres in front of you outside built-up areas so cars can overtake, and at least 30 metres behind you for the warning triangle when you break down.

Frequently Asked Questions

How many questions are on the Cameroon heavy-vehicle theory test and what is the pass mark?

The Ministry of Transport paper has 40 multiple-choice questions in two parts of 20, each carrying one mark. The pass mark is an average of 12/20, that is 24 correct answers out of 40, and the paper lasts 60 minutes.

What are the eligibility requirements for Category C, D and E licences in Cameroon?

The Cameroonian licensing arrêté sets a minimum age of 21 for Categories C and D and 18 for Category E, and requires 2 years' effective driving on a Category B licence for C, 1 year on a Category C licence for D, and 2 years on a Category C licence for E. A favourable medical certificate is required for all of them, plus a criminal record extract less than three months old for Category D. Candidates must be presented by an approved driving school and may sit only one category per examination.

What are the speed limits for heavy goods and passenger vehicles in Cameroon?

Article 90 of the CEMAC Highway Code allows 40 km/h in built-up areas for any vehicle over 3,500 kg. Outside built-up areas it allows 90 km/h between 3,500 and 12,500 kg and for all public passenger transport, 60 km/h above 12,500 kg or when towing a trailer over 750 kg, and 50 km/h for other machines. Cameroon's own road traffic decree is stricter in built-up areas, capping heavy vehicles at 30 km/h.

What are the axle and gross weight limits at Cameroonian weighbridges?

Article 20 of the CEMAC Highway Code allows 13 tonnes on a single axle, 21 tonnes on a tandem group and 27 tonnes on a tridem group, with gross laden weight capped at 50 tonnes. Weighing is compulsory for any vehicle over 3.5 tonnes on a road equipped for it, and overload fines rise from 25,000 to 75,000 FCFA per excess tonne.

How often must a truck or bus pass technical inspection in Cameroon?

Article 80 of the CEMAC Highway Code requires goods vehicles, tankers, dangerous goods vehicles and tractor units to be inspected every 6 months, rental vehicles every 4 months, and public passenger transport and driving-school vehicles every 3 months. Private cars are inspected annually.

Is this practice bank the official Ministry of Transport examination?

No. The official paper is set by the Ministry of Transport in French and English and its questions are not published. This is a free English-language multiple-choice study adaptation written from the CEMAC Community Highway Code, Cameroon's road traffic regulations and standard heavy-vehicle practice. It is not an official translation, a reproduction of official items, or a simulation of the image-interpretation half of the real paper.
