Driving with a trailer or caravan requires some preparation. Weight, length, wind resistance… These factors affect handling, increase braking distances, and demand more attentive driving. Before setting off, make sure you are familiar with the applicable regulations: speed limits, mandatory equipment, toll categories… This information is essential to ensure your safety and avoid unpleasant surprises on the road. This guide will help you travel confidently on the motorway with your trailer or caravan, whether you're heading off on holiday or traveling for business.

What are the rules to know when driving with a trailer or caravan?

Towing a caravan or trailer on the motorway requires following certain specific rules:

  • Passengers prohibited in the caravan: For safety reasons, it is strictly forbidden to transport people inside the caravan during the journey. All passengers must travel in the towing vehicle.
  • Registration certificate required depending on weight: If the GVWR (Gross Vehicle Weight Rating) of your trailer or caravan exceeds 500 kg, separate registration is mandatory.
    Below this threshold, it can share the registration of the towing vehicle, but a duplicate license plate must be installed at the rear.
  • Motorway lanes: Trailers must travel in the right-hand lane. Overtaking is only permitted in the center lane, if there are three lanes in the same direction.

What are the speed limits stipulated by the Highway Code?

In accordance with Article R413-8 of the French Highway Code, vehicles with a maximum authorized laden weight exceeding 3.5 tonnes must comply with specific speed limits:

  • 90 km/h on motorways
  • 90 km/h on dual carriageways separated by a central reservation
  • 80 km/h on other roads

These speed limits are designed to ensure safety, taking into account longer braking distances and overall vehicle stability. In wet weather or poor visibility, these speeds may be further reduced.
Respecting these speed limits contributes to safer driving, both for you and other motorists.

What are the essential checks to perform on your vehicle before setting off?

Before setting off with a caravan or trailer, a few checks are essential—especially if the rig hasn't been used for a while.

  • Check the condition and pressure of the tires, including the spare.
  • Check the lights, electrical connections, and the entire hitch system.
  • Make sure the towing vehicle is suitable for the weight you'll be pulling.
  • Securely pack all items inside and keep them safe. Gas cylinders, for example, must remain closed during the journey.

A well-prepared trailer makes for a safer… and more peaceful journey!

What are the best practices to adopt when driving on the motorway?

On the motorway, staying alert is essential, especially when towing a trailer or caravan.
Remember to increase your following distance by at least 50% compared to when driving alone. When being overtaken by a truck, keep to the right to minimize the slipstream effect. When going downhill, use engine braking to prevent the brakes from overheating.

Also, adapt your driving in adverse weather conditions: crosswinds, slippery roads, or rain can affect the stability of your vehicle and trailer combination.

Smooth and anticipatory driving helps you better manage the inertia and weight of the vehicle and trailer, for a safer and more comfortable journey.

Tolls: What is the classification for your caravan or trailer?

Toll classification depends on the maximum authorized total weight (PTAC) of your caravan or trailer.

  • If the total weight of the vehicle and trailer combination is less than 3.5 tonnes, you are in class 1, like a light vehicle.
  • Above 3.5 tonnes, your vehicle and trailer combination is classified in class 2, also known as "intermediate".
