Driving tips with a trailer on European highways: Speed limits and safety

There is a significant difference between driving on a highway with a trailer and driving without one. It is not necessarily dangerous or complicated, but the vehicle combination behaves differently, and European highways have their own rules that may not always match what you are used to in Spain. Knowing these differences beforehand is what can make the difference between a peaceful trip and one with avoidable scares.
This article covers exactly that: the speed limits that apply in the main European countries and the driving habits you should adopt when carrying extra load behind you.
First, the limits: Each country at its own pace
One of the most common confusions among those traveling with a trailer through Europe is assuming that speed limits are the same in all countries. They are not, and in some cases, the difference can be considerable.
Spain
On the highway, the limit with a trailer is 90 km/h. On conventional roads with a general limit of 90 km/h, the ceiling for the combination drops to 80 km/h. This reduction applies regardless of the trailer's weight.
France
The key here is the PTRA (Total Authorized Rolling Weight), which is the sum of the tractor vehicle's GVWR plus the trailer's GVWR according to the technical data sheets. If this figure does not exceed 3,500 kg, the limits are the same as for a passenger car: 130 km/h on highways (110 km/h in rain) and 80 km/h on conventional roads. For most drivers with a normal car and a light trailer, this is the case.
If the combination exceeds 3,500 kg PTRA, the limit drops to 90 km/h on highways and 80 km/h on roads.
Belgium
If your route passes through Belgium, the regulations are quite reasonable for light trailers: 120 km/h on highways and 90 km/h on conventional roads. However, in urban and residential areas, the limits drop significantly (20-30 km/h in some areas), so it is wise to pay attention to city signage.
Germany
On the Autobahn, the general limit with a trailer is 80 km/h, regardless of the fact that some sections have no limit for vehicles without trailers. There is a special authorization called Zulassung Tempo 100 that allows driving at 100 km/h, but it requires ABS in the tractor and that the trailer meets a specific weight ratio. For a Spanish tourist on a one-off trip, this is not easy to manage, so it is sensible to assume 80 km/h as the limit.
Austria
Austria is one of the most comfortable countries for driving with a light trailer: for trailers up to 750 kg, the limit on highways is 100 km/h and on roads is 80 km/h. For heavier trailers, the limit may drop to 80 km/h on highways. Remember that Austrian highways require a vignette, and enforcement is quite strict.
Switzerland
Switzerland has some of the strictest regulations in the area: 80 km/h on both highways and conventional roads with a trailer, regardless of weight. You will also need the Swiss vignette to drive on its highways.
Italy, Portugal, and the Netherlands
As a quick reference for longer routes: in Italy, the limit on highways is 80 km/h. In Portugal, the general limit for passenger cars with light trailers is 100 km/h on highways. In the Netherlands, the usual limit is 90 km/h, although for light trailers, it can reach 100 km/h.
How the vehicle combination behaves on the road
Beyond legal limits, there are a series of changes in the behavior of the vehicle combination that should be kept in mind when driving on highways.
Safety distance
With a trailer, the total mass of the combination increases, and so does the braking distance. What a normal car resolves in a few meters may require much more with a trailer. The practical advice is simple: increase the safety distance more than you think is necessary.
Side winds and overtaking trucks
This is probably the point that surprises first-time trailer drivers the most. When a truck overtakes you (or you overtake it), the suction effect and the side wind it generates can destabilize the combination in the blink of an eye. Keep the steering wheel firm, reduce speed slightly before the truck is alongside you, and avoid sudden corrections.
Lane changes
Lane changes with a trailer require more planning. The combination is longer, takes up more space, and responds more slowly to direction changes. Signal well in advance and make sure you have the space you need before moving the wheel.
Braking on highways
Avoid sudden braking whenever possible. On the highway, the ideal is to anticipate deceleration by gradually releasing the accelerator and using the brake gently.
Avoiding the snaking effect: Stability tips
If you have ever seen a caravan or trailer oscillating from side to side on a highway, you know what we are talking about. This pendular movement (known as snaking) can appear when driving at high speeds with an improperly loaded trailer.
The best way to avoid it is prevention: distribute the load well (more weight in the front part of the trailer, near the hitch), do not exceed the recommended speed, and avoid sudden maneuvers.
If the trailer starts to oscillate: progressively release the accelerator, keep the steering wheel straight, and do not brake. Braking can amplify the movement instead of correcting it.
Stops and checks during the journey
On long highway journeys, it is advisable to stop approximately every two hours to check that everything is still in order:
- Check that the straps and load anchors are still correctly placed and tight.
- Visually check the trailer lights.
- Make sure the hitch is still securely fastened.
What you should always carry with you
Regardless of the country, basic documentation is essential:
- Vehicle registration for the tractor and technical data sheet for the trailer.
- Valid ITV (technical inspection) for the tractor vehicle.
- Insurance that explicitly covers trailer use in the destination countries.
- Reflective vest accessible from the cabin and warning triangle. In Germany, a first-aid kit is mandatory.
Driving with a trailer is not complicated
But it is different. Knowing the limits that apply in each country and adopting calmer driving habits is all it takes for the trip to go well. If the trailer is well-designed, everything is easier from the start. The LittleWay Team folding trailer is approved and designed specifically for motorcycles, which already eliminates many of the variables that complicate these types of trips.
