Welcome to the lesson on towing rules for your Category B license! Within the 'Towing, Trailers, and Loads' unit, this lesson clarifies exactly what you can legally tow in the Netherlands. Understanding these weight limits is crucial for both passing your CBR theory exam and ensuring safety on the road.

Driving with a trailer adds complexity and responsibility. In the Netherlands, specific regulations govern what kind of trailer you can legally tow with a standard Category B driving license. Understanding these rules is crucial not only for compliance with Dutch road law but also for ensuring your safety and the safety of other road users. This lesson will detail the legal requirements, critical weight limits, and essential safety practices for towing a trailer with your Category B license.
The cornerstone of Dutch towing regulations is the Maximum Authorised Mass (MAM), known in Dutch as maximale toegestane massa. This value determines the legal limits for vehicles and trailers. It's not just about the weight you are currently towing, but the maximum weight the vehicle or trailer is designed and certified to carry.
The maximum load a vehicle or trailer is permitted to carry, according to the manufacturer, including its own unladen weight and its maximum payload. In Dutch, this is referred to as maximale toegestane massa.
The trailer's MAM represents the absolute heaviest it can be when fully loaded with cargo and any additional equipment. This value is set by the manufacturer and is a critical figure for determining whether your Category B license is sufficient for towing it. It’s important not to confuse the trailer's MAM with its current load or unladen weight. Even if a trailer is empty, its MAM is the figure used for legal calculations.
For instance, a trailer might have an unladen weight of 300 kg and a load capacity of 700 kg, making its MAM 1000 kg. If you only load 200 kg into it, its actual laden weight would be 500 kg, but for licensing purposes, its MAM of 1000 kg is what matters.
Similarly, the towing vehicle also has a Maximum Authorised Mass. This includes the vehicle's own weight, fuel, passengers, and any cargo it can carry internally. This value is critical when calculating the combined weight of the car and trailer, as it forms one half of the equation for the 3,500 kg combined MAM rule.
Just like with trailers, the vehicle's MAM is a fixed design limit, not its current operating weight. For example, a large SUV might have a MAM of 2,500 kg, even if it's currently only carrying a driver and minimal luggage.
To comply with towing regulations, you must accurately identify the MAM values for both your towing vehicle and the trailer. This information is readily available on the official Dutch vehicle registration document, known as the Kentekenbewijs.
The Kentekenbewijs contains technical specifications for the vehicle or trailer, including the maximale toegestane massa. It's typically listed under a specific code or heading related to weights. Always consult the official document or the vehicle's manufacturer data to ensure you have the correct figures. Relying on estimates or incorrect information can lead to legal infractions and safety risks.
With a standard Dutch Category B driving license, you are allowed to tow trailers under two distinct conditions. You must always ensure that your towing setup complies with at least one of these two rules.
Before towing any trailer, always perform a quick check:
The first and most straightforward rule states that you can always tow a trailer with a Maximum Authorised Mass (MAM) of up to 750 kg (750 kg or less), regardless of the towing vehicle's MAM.
This rule simplifies compliance for small and light trailers often used for garden waste, small camping equipment, or compact luggage carriers. Because these trailers are inherently lighter and impose less strain on the towing vehicle's braking and handling systems, the combined weight calculation with the towing vehicle's MAM is not necessary under this specific condition.
However, even though the combined MAM isn't calculated for licensing purposes here, the towing vehicle must still be physically capable of towing the trailer and fitted with an appropriate towing hitch. The physical towing capacity of your vehicle (often found in the vehicle's manual or on the tow bar itself) should never be exceeded.
If the trailer's Maximum Authorised Mass exceeds 750 kg, you may still tow it with a Category B license, provided a crucial condition is met: the combined MAM of the towing vehicle and the trailer does not exceed 3,500 kg.
The sum of the Maximum Authorised Mass (MAM) of the towing vehicle and the Maximum Authorised Mass (MAM) of the trailer. This total mass is a key factor in determining the required driving license category.
To apply this rule, you must add the MAM of your car to the MAM of your trailer. If this total sum is 3,500 kg or less, your Category B license is sufficient. For example, if your car has a MAM of 2,000 kg and you want to tow a trailer with a MAM of 1,500 kg, the combined MAM is 3,500 kg (2,000 kg + 1,500 kg). This combination is permissible with a Category B license.
This rule acknowledges that heavier combined loads demand more from the vehicle in terms of braking, acceleration, and stability. Exceeding this 3,500 kg limit can severely impair vehicle handling, increase stopping distances, and pose significant safety risks.
If your towing requirements exceed the limits of the standard Category B license, you will need to obtain a higher category license: the BE driving license.
A higher category driving license that permits the towing of trailers where the combined Maximum Authorised Mass (MAM) of the towing vehicle and trailer exceeds 3,500 kg, or where the trailer's MAM itself is exceptionally high. It requires separate training and a practical examination after obtaining a Category B license.
You will need a BE license if:
Obtaining a BE license involves additional training and a separate practical examination, which focuses on the specific skills and knowledge required for safely handling heavier and larger trailer combinations. This ensures that drivers have the competency to manage more demanding towing scenarios, promoting road safety.
Beyond the weight limits, several other regulations and best practices ensure safe and legal towing on Dutch roads. Adhering to these is vital to prevent accidents and avoid legal penalties.
The foundational legal framework for towing in the Netherlands is provided by the Reglement Verkeersregels en Verkeerstekens 1990 (RVV 1990), specifically Section 22. This section outlines the general requirements for towing and the conditions under which different license categories apply. These regulations are designed to maintain vehicle safety, prevent overloading, and reduce accident risks. Drivers are expected to be familiar with these rules as part of their driving competency.
For any towing operation, both the towing vehicle and the trailer must meet specific equipment standards:
When towing a trailer, especially on motorways or during overtaking maneuvers, it is crucial to maintain a safe following distance. In the Netherlands, there is a specific safety guideline often referred to as the 5-metre tail-gating rule. This recommendation emphasizes that when towing, the following vehicle should maintain at least 5 meters distance during overtaking. This rule addresses situations where a sudden stop by the towing combination could lead to a rear-end collision if the following driver fails to maintain a safe distance. While the general rule for safe following distance is 2 seconds, the 5-meter guideline highlights the increased braking distance and stability challenges associated with towing.
Driving with a trailer often necessitates adjusted speed limits and increased caution:
Ignorance of towing regulations is not a valid excuse, and violations can lead to severe consequences. Drivers must be aware of common pitfalls to avoid potential fines, license issues, and dangerous situations.
Let's illustrate these rules with a few common driving situations.
To navigate the regulations effectively, a clear understanding of the specific terminology is essential.
Understanding the regulations for towing with a Category B license in the Netherlands is fundamental for safe and legal driving. By familiarizing yourself with MAM definitions, the two core towing rules, and essential safety practices, you can confidently operate a vehicle with a trailer and avoid common pitfalls. Always refer to your vehicle and trailer documentation, and consider advanced training (like a BE license) if your towing needs exceed the standard Category B limits.

These explanations help you understand key concepts, lesson flow, and exam focused study goals.
The primary rule is that you can always tow a trailer with a Maximum Authorised Mass (MAM) of up to 750 kg. This is known as the standard limit for a Category B license. You must ensure your vehicle is capable of towing this weight and that the trailer is properly connected and secured.
If the trailer's MAM exceeds 750 kg, you can still tow it with a Category B license, but only if the combined MAM of your car and the trailer does not exceed 3,500 kg. You must check the MAM for both your vehicle and the trailer on their registration documents (kentekenbewijs).
The MAM, also known as 'toelaatbaar maximummassa' or 'MTM' in Dutch, is listed on the vehicle's registration certificate (kentekenbewijs). For your car, it's usually found on section '1.3' and for the trailer on its own registration document.
You will need a Category BE license if the combined MAM of your car and trailer exceeds 3,500 kg, or if the MAM of the trailer alone is more than 3,500 kg (though this is rare for standard passenger cars).
Yes, always ensure your trailer's lights are functioning correctly, that any load is securely fastened and within the trailer's payload capacity, and that you understand how towing affects your vehicle's braking, acceleration, and handling. You must also be aware of specific speed limits when towing.
