Towing a trailer in Belgium comes with specific rules tied to weight limits that often confuse drivers. This article breaks down exactly when your standard Category B licence is sufficient and when you must obtain a Category BE licence, explaining the critical Masses Authorisées (MAM) for both the trailer and the combined vehicle. Understanding these distinctions is vital for legal compliance and safe driving on Belgian roads.

Towing a trailer in Belgium, whether it's for a caravan holiday, transporting a horse, or moving goods, involves a set of specific regulations that many drivers find confusing. The standard Category B driving licence, commonly held by car drivers, covers a basic level of trailer towing. However, Belgian traffic law, in line with European directives, sets clear boundaries regarding the weight of the trailer and the combined vehicle. Understanding these rules is not just a matter of compliance; it's crucial for safe towing practices and for passing your Belgian driving theory test. This article aims to demystify the conditions under which your Category B licence is sufficient and when you will need to obtain the additional Category BE licence.
The core of the regulations revolves around the Maximum Authorised Mass (MAM), known in Belgium as the Masse Maximale Autorisée (MMA). This figure, found on the vehicle's registration documents, represents the maximum laden weight allowed for the vehicle or trailer. Navigating these MAM limits is the key to understanding Belgian trailer towing requirements and ensuring you are legally permitted to tow the load you intend to carry.
Your Category B driving licence in Belgium allows you to operate a passenger car or similar vehicle with a Maximum Authorised Mass (MMA) not exceeding 3,500 kg, designed for no more than eight passengers plus the driver. Crucially, this licence also permits you to tow a trailer under certain conditions. These conditions are primarily dictated by the weight of the trailer itself and the total combined weight of the vehicle and trailer.
The most straightforward rule for Category B licence holders relates to the trailer's MMA. If the trailer you intend to tow has a Maximum Authorised Mass of 750 kg or less, your standard Category B licence is sufficient, regardless of the towing vehicle's weight. This covers many smaller trailers, such as utility trailers or lightweight garden trailers.
However, it is vital to always check the specific MMA of the trailer you are using. This information will be clearly stated on the trailer's identification plate or its registration documents. Many smaller, unbraked trailers fall into this category, but even some braked trailers can have an MMA below 750 kg.
The situation becomes more complex when the trailer's MMA exceeds 750 kg. In such cases, your Category B licence may still be sufficient, but only if two additional conditions are met simultaneously. Firstly, the combined Maximum Authorised Mass of the towing vehicle and the trailer together must not exceed 3,500 kg. Secondly, the Maximum Authorised Mass of the trailer must not be greater than the unladen mass of the towing vehicle.
This means that even if your trailer weighs more than 750 kg, you can still tow it with a Category B licence if the total weight of the vehicle and trailer is under 3,500 kg, and the trailer isn't heavier than the car itself when empty. This is a common scenario for many lighter caravans or smaller boat trailers when towed by compact cars.
The Maximum Authorised Mass (MMA), or Masse Maximale Autorisée, is the maximum weight that a vehicle or trailer is legally allowed to carry when fully loaded. This includes the weight of the vehicle or trailer itself, plus its payload, passengers, and any fuel or fluids. This figure is crucial for determining licence requirements and ensuring safe operation.
The requirement for a Category BE licence becomes mandatory when your towing situation exceeds the allowances of the Category B licence. This occurs under two primary scenarios, which are often intertwined.
The most common reason for needing a Category BE licence is when the combined Maximum Authorised Mass of the towing vehicle and the trailer exceeds 3,500 kg. Even if the trailer's MMA is less than 750 kg, if the total combined weight surpasses this threshold, a BE licence is typically required for vehicles that are not specifically covered by other rules. However, for trailers under 750kg MMA, the B licence is generally sufficient even if the combined weight exceeds 3500kg, unless specified otherwise by the vehicle manufacturer.
Therefore, the definitive trigger for needing a Category BE licence is when your trailer has a Maximum Authorised Mass greater than 750 kg, AND the combined Maximum Authorised Mass of the towing vehicle plus the trailer exceeds 3,500 kg. This covers a significant range of heavier loads.
For instance, towing a typical horse box, which can have an MMA of 1,500 kg to 2,500 kg, with a standard car could easily push the combined weight over the 3,500 kg limit, necessitating a BE licence. Similarly, larger touring caravans or boat trailers often fall into this category. It is essential to consult the technical specifications of both your towing vehicle and the trailer to accurately calculate the combined MMA.
Always double-check the MMA of both your towing vehicle and your trailer. This information is usually found on a plate or sticker affixed to the vehicle or trailer itself. Official documentation, such as the vehicle's registration certificate (carte grise/kentekenbewijs), will also provide these figures.
Understanding these regulations has direct practical implications for Belgian drivers undertaking various towing activities. The nuances of weight limits can catch even experienced drivers unaware, leading to potential fines and safety risks during their theory test preparation.
For those looking to tow a caravan, the crucial figure is the combined weight. A lighter caravan might be towable with a Category B licence if the combined MMA is under 3,500 kg. However, many larger, fully equipped touring caravans, especially when combined with a moderately sized car, will exceed this limit, requiring a Category BE licence. The same principle applies to horse boxes. The weight of the horse box itself, plus the weight of the horse(s) and any equipment, can quickly elevate the total MMA, making the BE licence essential.
Boat trailers, especially those carrying larger vessels, are another common area where the BE licence is needed. The boat, trailer itself, and associated equipment can easily result in a trailer MMA exceeding 750 kg and a combined MMA well over 3,500 kg. For any load that is substantial or bulky, meticulous attention to the weight specifications is paramount.
Belgium also offers an intermediate option known as "Code 96" for those whose towing needs fall between the standard Category B and the full Category BE licence. This code is added to your Category B licence upon passing a specific practical test.
A Category B licence with Code 96 allows you to tow a trailer with a Maximum Authorised Mass greater than 750 kg, provided that the combined Maximum Authorised Mass of the vehicle and trailer does not exceed 4,250 kg. This option is ideal for drivers who occasionally need to tow slightly heavier loads than permitted by a standard Category B licence but do not require the full capabilities of a Category BE licence. It offers a more flexible solution for many common towing situations without the more extensive training and testing associated with the BE category.
When towing a trailer in Belgium, speed limits can also differ. While the general motorway speed limit for a car is 120 km/h, this often changes when towing. For a Category B vehicle towing a trailer, the maximum speed on motorways is typically reduced to 90 km/h, and on other roads, it may be even lower, often 70 km/h or 50 km/h depending on the road type.
It is essential to always observe the posted speed limits, which may be indicated by supplementary signs showing a car and trailer. Furthermore, remember that vehicle stability and braking distance increase significantly when towing. Always drive at a speed that allows you to maintain full control of the vehicle and trailer combination, especially in adverse weather conditions or when encountering traffic.
Code 96 is an endorsement on a Category B driving licence in Belgium that permits the holder to tow a trailer with a Maximum Authorised Mass (MMA) exceeding 750 kg, provided the combined MMA of the vehicle and trailer does not exceed 4,250 kg. This status is obtained by passing a specific practical driving test.
To provide a clear overview, here is a summary of the key weight limits and the corresponding licence requirements for towing a trailer with a vehicle for which you hold a Category B licence:
| Trailer MMA (Maximum Authorised Mass) | Combined Vehicle + Trailer MMA | Required Licence |
|---|---|---|
| ≤ 750 kg | Any | Category B |
| > 750 kg | ≤ 3,500 kg | Category B |
| > 750 kg | > 3,500 kg and ≤ 4,250 kg | Category B + Code 96 |
| > 750 kg | > 4,250 kg and ≤ 7,000 kg | Category BE |
Note: The figures for Category BE are based on the combined MMA not exceeding 7,000 kg when the trailer MMA is over 750 kg. It's important to note that some older regulations or specific vehicle manufacturer guidelines might differ slightly, particularly concerning the total permissible weight for certain vehicle types. Always verify with official sources and your vehicle's manual.
Understanding these rules is a fundamental part of your preparation for the Belgian driving theory test. Exam questions frequently cover these weight limits and licence requirements, often posing scenarios where you must determine the correct licence category needed for towing. Pay close attention to the wording of questions, particularly regarding the MMA of the trailer and the combined MMA. Common pitfalls include focusing solely on the trailer weight or overlooking the 3,500 kg combined limit.
The Belgian theory exam will test your knowledge of these regulations in practical driving scenarios. Incorrectly answering questions about trailer towing can lead to a failed exam, so ensure you have a firm grasp of the weight limits and licence categories.
For instance, you might encounter a question asking whether a Category B licence is sufficient to tow a trailer with an MMA of 800 kg if the combined weight of the car and trailer is 3,400 kg. The correct answer would be yes, as it meets the conditions of the combined weight being under 3,500 kg. Conversely, if the combined weight was 3,600 kg, the answer would be no, and you would need either Code 96 or a BE licence, depending on the specific MMA of the trailer and the combined vehicle.
Navigating the rules for towing trailers in Belgium requires a clear understanding of Maximum Authorised Mass (MMA) for both the trailer and the combined vehicle. While your Category B licence covers lighter trailers up to 750 kg MMA, or heavier trailers under specific combined weight conditions, any situation exceeding these limits necessitates further licensing. Whether you need to upgrade to Code 96 for combined weights up to 4,250 kg or obtain a full Category BE licence for heavier combinations, ensuring you have the correct licence is vital for legal compliance, safety on Belgian roads, and successful completion of your driving theory tests.
