Anyone traveling with a horse is really insuring three things at once: the vehicle, the trailer or truck itself, and the horse standing inside it. In conversation, these three often get mixed up, even though each has its own coverage — and the most expensive misunderstanding is assuming "the car insurance will cover it." Below is how it's structured, piece by piece.
The Trailer: Attached, Detached, and the Trailer Itself
For damage that an attached trailer causes to others, the main rule is that it's covered by the WA (Wettelijke Aansprakelijkheid — third-party liability) insurance of the towing vehicle. That generally takes care of liability en route — but not everything. A detached or parked trailer can be treated differently, and more importantly: damage to or theft of your own trailer is never covered under WA coverage. A separate trailer insurance policy (hull coverage) exists for that, worth it as the trailer gets newer and more expensive. What a trailer costs and what to check when buying one is covered in Buying or renting a horse trailer.
The Horse Truck: Its Own Vehicle, Its Own Mandatory Insurance
A horse truck is a motor vehicle and therefore must carry mandatory WA insurance of its own — it doesn't ride along on another policy. On top of that, hull coverage is a consideration like with any car, with one horse-specific point to note: the fit-out (stalls, living quarters, equipment) often represents a substantial part of the value and must be explicitly included in the value declaration to be covered. For driver's license and weight rules around combinations — where the choice of truck often starts — see transporting a horse as a private individual.
The Horse En Route: The Coverage That Isn't Automatic
The WA coverage on a car or truck covers damage to others — not your own cargo, and to the insurer, your own horse is exactly that. If the horse is injured en route, no vehicle policy pays for it. Anyone who wants to cover that risk should look at transport coverage: sometimes a module on an existing horse insurance policy, sometimes a separate transport insurance policy for occasional trips. If you regularly transport other people's horses, the conversation shifts to carrier liability and business coverage — the territory of insurance for a horse business.
What to Check When Taking Out a Policy
Four questions that make the difference when getting a quote or checking a policy: is the value declaration accurate (trailer including fit-out)? Does the policy set requirements for maintenance or inspection, and do you meet them? Does the coverage also apply abroad — relevant for anyone competing or training in Belgium? And how is theft covered, including the requirements for storage and a hitch lock? Policies differ on exactly these points; ask about them and keep the answer on file.
In Short
When attached, the trailer's WA coverage rides along with the towing vehicle; a truck has its own mandatory WA. Damage to your own trailer or truck requires hull coverage, and the horse itself is only covered en route with a separate transport policy. Anyone who has the value declaration, inspection requirements, and coverage abroad clear can wrap it up with the insurer in a single phone call.
