Towing Rules for a Category B Driving License in the Netherlands

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.

Understanding Maximum Authorised Mass (MAM) for Towing

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.

Definition

Maximum Authorised Mass (MAM)

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.

What is Trailer MAM?

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.

What is Vehicle MAM?

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.

Locating MAM on Dutch Registration Documents (Kenteken)

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.

The Two Main Rules for Towing with a Category B License

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.

Tip

Before towing any trailer, always perform a quick check:

  1. What is the trailer's MAM?
  2. What is the towing vehicle's MAM? Armed with these two figures from your Kentekenbewijs, you can quickly determine if you meet the Category B requirements.

Rule 1: Towing Trailers up to 750 kg MAM

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.

Rule 2: Towing Heavier Trailers (Combined MAM up to 3,500 kg)

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.

Definition

Combined MAM

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.

When a BE Driving License is Required for Towing

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.

Definition

BE Licence

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:

  • The trailer's MAM is greater than 750 kg, AND the combined MAM of the towing vehicle and trailer exceeds 3,500 kg.
  • In some cases, if the trailer's MAM is exceptionally high (e.g., over 3,500 kg by itself), a BE license might be necessary even if the towing vehicle has a very low MAM.

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.

Key Regulations and Safety Practices for Towing in the Netherlands

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.

Essential Trailer Equipment and Connection Requirements

For any towing operation, both the towing vehicle and the trailer must meet specific equipment standards:

  • Towing Hitch: The towing vehicle must be fitted with a manufacturer-approved towing hitch (trekhaak) that is compatible with the trailer's coupling and rated for the load being towed. Improvised or unapproved hitches are illegal and extremely dangerous.
  • Lights: All trailers, especially those with a MAM greater than 750 kg, must be equipped with functioning trailer lights. This includes taillights, brake lights, and turn signals that mirror those of the towing vehicle. In the Netherlands, specific regulations for bulb diameter (e.g., at least 150 mm) exist for certain lights. Proper lighting ensures visibility, especially in low-light conditions or adverse weather.
  • Braking System: Trailers with a MAM over 750 kg are generally required to have their own braking system (e.g., overrun brakes). This significantly enhances the combined braking capability and prevents the trailer from pushing the towing vehicle.
  • Safety Cable (Ongeremde Aanhanger Remkabel): For unbraked trailers, a safety cable must be attached from the trailer's drawbar to a designated eyelet or attachment point on the towing vehicle. If the trailer detaches, this cable activates the trailer's brakes or prevents it from becoming fully separated, providing a critical safety measure.
  • Tires: Ensure both the towing vehicle and trailer have tires in good condition with adequate tread depth and correct pressure for the load.

Maintaining Safe Distances: The 5-Metre Tail-Gating Rule

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.

Speed Limits and Conditional Driving with a Trailer

Driving with a trailer often necessitates adjusted speed limits and increased caution:

  • General Speed Limits: While towing a trailer, you must adhere to the standard speed limits for cars, which are typically 100 km/h on autowegen (expressways) and autosnelwegen (motorways), and 50 km/h within built-up areas. However, your combined vehicle and trailer performance might dictate a lower safe speed.
  • Weather Conditions: On wet, icy, or foggy roads, braking distances increase significantly. It is imperative to reduce your speed and increase your following distance well beyond the minimums when towing in adverse weather. The added mass of a trailer makes the vehicle more susceptible to skidding and loss of control.
  • Visibility: During night-time or in low-visibility conditions (fog, heavy rain), ensuring all trailer lights are clean and fully functional is paramount. Reduced visibility increases the risk of other road users not seeing your trailer.
  • Road Type: On urban streets, the increased turning radius required for a trailer means you must exercise extreme caution, especially near vulnerable road users such as cyclists and pedestrians. On motorways, ensure your vehicle has sufficient power and stability to maintain appropriate speeds without struggling.

Common Mistakes and Consequences of Violating Towing Rules

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.

  1. Towing an Overweight Trailer with a Category B License:
    • Why wrong: Exceeds the legal combined MAM limit of 3,500 kg, or the 750 kg trailer MAM rule if applicable.
    • Correct practice: Obtain a BE license or use a lighter trailer/towing vehicle combination.
    • Consequence: Significant fines, potential licence revocation, vehicle impoundment, and insurance invalidation in case of an accident.
  2. Overloading the Trailer Itself Beyond its MAM:
    • Why wrong: Even if the combined MAM is within limits, exceeding the trailer's individual MAM (load capacity) can distort its frame, reduce braking effectiveness, and increase the risk of a tail flip (snaking).
    • Correct practice: Adhere strictly to the trailer's specified load capacity.
    • Consequence: Fines, safety hazards, structural damage to the trailer.
  3. Using a Trailer with MAM > 750 kg on an Unsuitable Vehicle:
    • Why wrong: While legally within combined MAM limits, the towing vehicle might not have sufficient engine power, chassis strength, or braking capability for the specific trailer.
    • Correct practice: Always ensure the towing vehicle's technical specifications (found in its manual) confirm it is rated to tow the trailer's actual laden weight.
  4. Attaching a Trailer to a Temporary or Unapproved Hitch:
    • Why wrong: Improvised hitches or those not specifically designed for the vehicle can fail, causing the trailer to detach, leading to severe accidents.
    • Correct practice: Always use a manufacturer-approved towing hitch installed according to specifications.
  5. Ignoring the 5-Metre Tail-Gating Rule During Overtaking:
    • Why wrong: When towing, increased stopping distances necessitate greater buffer zones, especially for following traffic. Failure to ensure this distance can lead to rear-end collisions.
    • Correct practice: Maintain at least a 5-metre buffer, particularly when overtaking or merging.
  6. Towing a Trailer Without Proper Lights:
    • Why wrong: Violates lighting regulations and significantly reduces the visibility of your combined vehicle, especially at night or in bad weather.
    • Correct practice: Ensure all trailer lights (taillights, brake lights, turn signals) are functional and clean before every journey.
  7. Failing to Check Trailer's Legal Registration:
    • Why wrong: An unregistered trailer may not meet safety criteria, leading to legal issues and potential fines.
    • Correct practice: Verify the trailer's registration status and ensure its Kentekenbewijs is valid.
  8. Incorrectly Calculating Combined MAM:
    • Why wrong: A simple arithmetic error can lead to unintentional overloading and non-compliance.
    • Correct practice: Double-check your addition of the towing vehicle's MAM and the trailer's MAM.

Practical Scenarios: Applying Towing Rules

Let's illustrate these rules with a few common driving situations.

Scenario A: Towing a Small Garden Trailer

  • Setting: Urban route, clear weather.
  • Vehicle: Compact car, 1,800 kg MAM.
  • Trailer: Small garden trailer, 650 kg MAM.
  • Rule Applied: Since the trailer's MAM (650 kg) is less than or equal to 750 kg, the 750 kg Rule applies.
  • Correct Behavior: The Category B license permits this combination. Ensure the trailer is properly hitched and its basic lights (if required by size/visibility) are functional.
  • Incorrect Behavior: Overloading the garden trailer beyond its 650 kg MAM, or using an unapproved hitch.
  • Outcome: Legal and safe towing, provided all other equipment and operational checks are performed.

Scenario B: Towing a Medium-Sized Caravan

  • Setting: Motorway with a 100 km/h speed limit.
  • Vehicle: SUV, 2,200 kg MAM.
  • Trailer: Caravan, 1,300 kg MAM.
  • Rule Applied: The trailer's MAM (1,300 kg) is greater than 750 kg, so we apply the Combined MAM Rule.
    • Combined MAM = Vehicle MAM (2,200 kg) + Trailer MAM (1,300 kg) = 3,500 kg.
  • Correct Behavior: The Category B license permits this combination as the combined MAM is exactly 3,500 kg (not exceeding it). The driver must maintain safe braking distances, ensure all trailer lights (including brake lights and indicators) are operational, and observe the 5-metre tail-gating rule when appropriate.
  • Incorrect Behavior: If the driver decides to add more load, increasing the caravan's MAM to 1,400 kg (making combined MAM 3,600 kg), it would violate the Category B limits and require a BE license.
  • Outcome: Legal towing if the combined weight stays at or below 3,500 kg; otherwise, a BE license is required, or penalties will apply.

Scenario C: Towing a Horse Trailer at Night

  • Setting: Evening on a dark, rural road.
  • Trailer: Horse trailer, 1,500 kg MAM.
  • Rule Applied: Trailer lighting regulations (as MAM > 750 kg).
  • Correct Behavior: Before starting the journey, the driver must ensure all brake lights, taillights, and turn signals on the trailer are clean, functional, and correctly connected to the towing vehicle's electrical system.
  • Incorrect Behavior: Continuing to tow the horse trailer with non-functional lights. This poses a severe visibility risk to other drivers on dark roads and is a direct violation of Dutch lighting regulations.
  • Outcome: Potential fines, liability in case of a collision due to lack of visibility, and immediate instruction from police to rectify the issue before continuing.

Learn how the lesson is structured, which driving theory objectives it supports, and how it fits into the overall learning path of units and curriculum progression in the Netherlands. These explanations help you understand key concepts, lesson flow, and exam focused study goals.

What is the main rule for towing a trailer with a Category B license in the Netherlands?

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.

What if the trailer's MAM is over 750 kg?

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).

How do I find the Maximum Authorised Mass (MAM) for my car and trailer?

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.

When do I need a Category BE license?

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).

Are there any other important considerations when towing?

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.
