Towing a trailer in Switzerland involves unique rules that differ from other countries. This guide breaks down the essential regulations, including the mandatory 80 km/h speed limit for all trailer combinations on any road, the combined weight limits for Category B license holders, and the necessity of a separate vignette for motorway access. Understanding these specific Swiss requirements is vital for both your driving theory exam and safe, legal towing.

Towing a trailer in Switzerland involves a specific set of rules designed to ensure safety and maintain traffic flow across its diverse road network. Unlike many other European countries, Switzerland imposes a strict, uniform speed limit for all vehicles towing trailers, regardless of road type. Furthermore, understanding weight limits and the mandatory vignette requirement is crucial for legal and safe travel. This comprehensive guide will equip you with the essential knowledge for passing your Swiss driving theory exam and for confident towing on Swiss roads.
One of the most significant and often surprising regulations for drivers towing trailers in Switzerland is the overarching speed limit. Regardless of whether you are on a national motorway, a main road, or a rural route, the maximum permissible speed when towing any type of trailer is strictly 80 km/h. This unified limit applies to all trailer combinations, including those with caravans, horseboxes, or utility trailers, and is a critical point tested in the Swiss driving theory examination. It is vital to internalize this rule as exceeding it carries significant penalties and risks.
The rationale behind this uniform speed limit is to account for the altered handling characteristics and increased braking distances associated with a trailer. Even on motorways, where standard passenger cars can travel at higher speeds, the presence of a trailer necessitates a reduction to 80 km/h. This ensures a greater margin of safety for both the towing vehicle, the trailer, and other road users, particularly in varied conditions such as changing weather or encountering mountainous terrain common in Switzerland.
Remember this key difference for your theory test: on Swiss motorways, while cars can go up to 120 km/h, a vehicle towing a trailer is limited to 80 km/h.
For drivers holding a standard Category B driving licence in Switzerland, there are specific weight limitations when towing a trailer. These regulations are closely aligned with EU standards, focusing on the maximum permissible mass (MAM) of both the towing vehicle and the trailer.
Primarily, a Category B licence holder can tow a trailer with an MAM of up to 750 kg without any additional licensing requirements beyond the standard B licence. This applies to unbraked trailers. However, if the trailer's MAM exceeds 750 kg, the combined MAM of the towing vehicle and the trailer must not exceed 3,500 kg. This is often referred to as the "3,500 kg towing limit." It's imperative to check the vehicle's registration documents (Fahrzeugausweis) for the precise MAM of both the towing vehicle and the trailer to ensure compliance.
The maximum permissible mass (MAM) of a vehicle or trailer, as stated in its registration documents, is the maximum total weight it can be, including the vehicle itself, passengers, and cargo.
It is also important to note that for heavier trailers exceeding 750 kg MAM, the trailer's MAM must not exceed the towing vehicle's unladen weight. These weight restrictions are crucial for vehicle stability and safe braking, and they are frequently tested in the driving theory exams. Exceeding these limits can lead to instability, loss of control, and severe legal consequences.
Using Switzerland's motorways and expressways requires a special annual toll sticker known as the "Autobahnvignette" or simply "Vignette." This rule applies not only to passenger cars and delivery vehicles but also, critically, to trailers. Therefore, if you intend to use Swiss motorways with a trailer, both the towing vehicle and the trailer must be properly equipped with a vignette.
The vignette costs CHF 40 and is valid for a calendar year, typically from December 1st of the preceding year to January 31st of the following year. For trailers, the vignette must be affixed to a clearly visible and non-removable part of the trailer itself, not on the towing vehicle's windscreen. In the case of the newer e-vignette system, the trailer's license plate must be registered electronically.
Driving on Swiss motorways without the required vignettes for both the towing vehicle and the trailer will result in a fine of CHF 200 per missing vignette, in addition to the mandatory purchase of the vignette itself.
The vignette system is managed by the Federal Office for Customs and Border Security (BAZG). You can purchase the sticker vignette at border crossings, petrol stations, and post offices. The e-vignette can be bought online. Understanding the vignette requirements is a fundamental part of preparing for the Swiss driving theory test, particularly questions related to motorway usage and vehicle documentation.
In Switzerland, trailers are considered separate vehicles and therefore require their own registration, including a dedicated licence plate (Kontrollschild) and a registration document (Fahrzeugausweis), issued by the cantonal road traffic office (Strassenverkehrsamt). This trailer plate must be illuminated at night. This means that even if you are using your personal car to tow a trailer, the trailer must have its own valid registration and plate.
For trailers with a maximum permissible mass exceeding 3,500 kg, periodic technical inspections, known as MFK (Motorfahrzeugkontrolle), are mandatory. These inspections ensure that the trailer meets all safety and technical standards required for road use. The VTS (Verordnung über technische Anforderungen an Strassenfahrzeuge) outlines these detailed technical requirements for all vehicles, including trailers.
The distinction between different types of trailers is also important. For instance, "Transportanhänger" are trailers designed for transporting people or goods, and further categorized into "Sachentransportanhänger" (goods transport trailers) and "Personentransportanhänger" (passenger transport trailers). The regulations, especially regarding weight and usage, can vary subtly between these types.

In Switzerland, any vehicle towing a trailer must adhere to a maximum speed limit of 80 km/h on all roads, including motorways.
With a Category B license, you can tow a trailer with a maximum permissible total weight of 750 kg (unbraked). If the trailer is braked, the combined weight of the towing vehicle and trailer must not exceed 3,500 kg, and the trailer's maximum permissible weight must not exceed the towing vehicle's unladen weight.
Yes, if you plan to use Swiss motorways or expressways with a trailer (up to 3.5 tonnes), the trailer must have its own valid motorway vignette sticker or e-vignette, in addition to the vignette on the towing vehicle.
Yes, the 80 km/h speed limit for trailer combinations is mandatory on all types of roads in Switzerland, not just motorways.
Yes, trailers in Switzerland typically require their own registration plate (Kontrollschild) and a Fahrzeugausweis (registration document) issued by the cantonal road traffic office (Strassenverkehrsamt).
