Driving in Austria with a trailer attached to your vehicle requires a thorough understanding of specific regulations, especially for those holding a standard Category B driving licence. Many drivers are unaware of the nuanced rules that apply, which can lead to significant fines and, more importantly, compromised safety on Austrian roads. This guide will thoroughly explain the legal framework, speed restrictions, weight limitations, registration necessities, and the often-overlooked vignette requirements for towing in Austria, ensuring you are well-prepared for both safe journeys and the Austrian theory driving exam.
The Austrian Kraftfahrgesetz (KFG) and Straßenverkehrsordnung (StVO) govern trailer towing. For holders of a standard Category B driving licence, the rules are specific and must be adhered to strictly. Primarily, a Category B licence permits you to tow trailers under certain weight and combination restrictions. This means you can generally tow unbraked trailers up to 750 kg maximum laden mass (MLM). Beyond this, you can also tow heavier braked trailers, but only if the combined maximum laden mass of the towing vehicle and the trailer does not exceed 3,500 kg. A crucial condition for heavier trailers is that the trailer's maximum laden mass must not exceed the towing vehicle's unladen weight. For those needing to tow heavier combinations regularly, obtaining a BE licence or completing a Code 96 training is advisable, as it significantly expands towing capabilities.
One of the most critical aspects that many drivers overlook when towing in Austria is the reduction in speed limits. While a standard passenger car up to 3.5 tonnes can typically travel at 130 km/h on an Autobahn, this limit is significantly reduced when a trailer is attached. Adherence to these reduced speeds is not just about legal compliance but is paramount for vehicle stability, braking efficiency, and overall safety, especially in diverse Austrian road conditions.
On Austrian Autobahnen (motorways), the maximum speed limit for a vehicle towing a trailer with a Category B licence is generally 100 km/h. This is a substantial reduction from the standard 130 km/h and is clearly indicated by road signage, although the lower limit is the default when towing. It's important to note that some specific Autobahnen might have further restrictions or variable speed limits due to environmental regulations or traffic conditions, which should always be observed.
For Schnellstraßen (expressways), the maximum speed limit when towing is typically 80 km/h. This restriction is in place to account for different road designs and potential hazards compared to Autobahnen. Similarly, on rural roads (Freiland), the speed limit is also generally capped at 80 km/h when towing a trailer. Within built-up areas (Ortsgebiet), the standard speed limit of 50 km/h applies to all vehicles, including those towing trailers, and this limit remains unchanged.
To provide a clear overview, here is a summary of the general speed limits when towing a trailer with a Category B licence in Austria:
| Vehicle Type/Combination | Speed Limit - Ortsgebiet | Speed Limit - Freiland | Speed Limit - Autostraße (Schnellstraße) | Speed Limit - Autobahn |
|---|---|---|---|---|
| Motorcycle, passenger car up to 3.5 tonnes | 50 km/h | 100 km/h | 100 km/h | 130 km/h |
| Combination up to 3.5 tonnes with light trailer (≤ 750 kg) | 50 km/h | 100 km/h | 100 km/h | 100 km/h |
| Combination < 3.5 tonnes with heavy trailer (< 3.5 tonnes MLM) | 50 km/h | 80 km/h | 80 km/h | 100 km/h |
| Combination > 3.5 tonnes, vehicle > 3.5 tonnes | 50 km/h | 70 km/h | 80 km/h | 80 km/h |
Note: The table above reflects general speed limits for passenger cars and lighter combinations. The specific limits for towing a trailer with a Category B licence in Austria are: 50 km/h in built-up areas, 80 km/h on rural roads and expressways, and 100 km/h on motorways (Autobahnen), unless otherwise signed.
Beyond speed limits, Austrian law mandates specific registration and equipment standards for trailers. Any trailer intended for use on public roads in Austria must have its own valid registration documents and a license plate. This means that if you are towing a trailer, it will likely need to have an Austrian license plate (Kennzeichen) and corresponding registration certificate (Zulassungsschein), unless it is a temporary or specific type of trailer under international agreements. The license plate must be clearly visible and illuminated from the rear.
Furthermore, the tow bar (Anhängerkupplung) fitted to the towing vehicle must be legally approved for use in Austria. This typically means it needs to have an ABE (Allgemeine Betriebserlaubnis) or a valid EU type-approval certificate. If a tow bar is not properly homologated, the vehicle combination will be considered not roadworthy, leading to potential fines and invalidation of insurance. This is a technical requirement that ensures the safety and integrity of the towing setup.
A particularly critical and often misunderstood rule in Austria pertains to the vignette system on motorways and expressways. While the towing vehicle requires its own vignette, a common oversight is failing to realise that trailers also require a separate vignette if they are being towed on toll roads. This applies to all types of trailers, including caravans and utility trailers, if they are being pulled on an Autobahn or Schnellstraße.
The vignette for the trailer must be purchased and affixed to the trailer itself, or if an e-Vignette is used, it must be registered to the trailer's license plate. The ASFINAG, the Austrian federal company responsible for toll collection, enforces these rules strictly. Failing to have a valid vignette on both the towing vehicle and the trailer can result in substantial fines for each vehicle, making it a costly mistake for unsuspecting tourists and residents alike.
Understanding these detailed rules for trailer towing is vital for passing the Austrian driving theory exam. Questions often target specific speed limits, weight restrictions, and the dual vignette requirement. Examiners frequently pose scenarios that test whether candidates know the correct speed for towing a specific type of trailer on different road types, or whether they recall that the trailer itself needs a vignette.
It's crucial to recall that for combinations exceeding 3.5 tonnes total mass, specific rules apply, and for Category B licence holders, these often involve stricter speed limits even beyond the general 100 km/h Autobahn limit for lighter combinations. The exam may present scenarios involving different trailer weights and road types to verify your comprehension of these nuances. Familiarise yourself with the table of speeds and the conditions under which heavier trailers can be towed to avoid confusion.
The regulations surrounding vehicle combinations and specific road usage in Austria can be complex. For a comprehensive understanding, consider delving into related topics that are frequently tested and essential for safe driving practices throughout the country.

With a Category B licence, the general speed limit when towing a trailer is 80 km/h on 'Freiland' (outside built-up areas) and 'Autostraße' (expressways). On 'Autobahn' (motorways), the limit is typically 100 km/h, reduced from the standard 130 km/h for cars, unless specific signage indicates otherwise. In built-up areas, the limit remains 50 km/h.
With a Category B licence, you can tow unbraked trailers up to 750 kg. For braked trailers, the maximum permissible total mass of the vehicle combination (car + trailer) is 3,500 kg, provided the trailer's maximum permissible mass does not exceed the towing vehicle's unladen weight. For heavier combinations, a BE licence or 'Code 96' training is required.
Yes, if the trailer combination is subject to tolls, the trailer itself requires a separate vignette sticker or e-Vignette. This applies to motorways and expressways. The vignette must be registered to the trailer's license plate. This is a common point of confusion and a frequent cause for fines.
'Code 96' is an extension for the Category B licence in Austria that allows towing heavier trailers. It permits vehicle combinations up to 4,250 kg total mass, requiring completion of a specific 7-hour practical training course without a separate exam. This is an alternative to obtaining a full BE licence for towing heavier trailers.
Yes, the tow bar must be homologated, meaning it must have an ABE (Allgemeine Betriebserlaubnis) or EU type approval. A non-homologated tow bar can render the vehicle non-roadworthy under Austrian law (KFG) and lead to fines.
