Temporary insurance for specialized trailers/semi-trailers: properly secure your occasional transport needs.

Heavy trailer, flatbed, semi-trailer? If the maximum authorized total weight (PTAC) exceeds 750 kg or the contents are significant, opt for dedicated insurance. Temporary insurance covers third-party liability, damage, theft, and contents for 1 to 90 days — suitable for occasional transport.
Whether for transporting construction equipment, vehicles, competition gear, or occasional freight, specialized trailers or semi-trailers can be invaluable. However, their often sporadic use requires adequate insurance coverage—especially if the transport is occasional, one-way, seasonal, or for professional purposes. Temporary insurance then emerges as the ideal solution: flexible, without long-term commitment, and capable of handling a variety of situations. This article explains when and why to take out temporary insurance, the coverages to prioritize, the conditions to check, and how KT Tempo can assist you.
1. Why temporary insurance for a specialized trailer or semi-trailer?
- Legal obligation according to weight : a trailer whose GVWR exceeds 750 kg must have its own insurance, separate from that of the towing vehicle.
- Occasional use : For a single transport (equipment, machinery, vehicle, goods, etc.), an annual contract may be excessive. Temporary insurance (1 to 90 days) covers only the necessary period.
- Specialized trailers or semi-trailers : boat trailer, flatbed, car carrier, construction site trailer, etc. These intensive or custom uses often require specific guarantees (damage, goods transported, liability).
- Flexibility and administrative simplicity : subscription is quick, duration adjustable according to need — ideal for one-off missions or unplanned transport.
2. Which uses are concerned?
Here are some concrete examples where temporary insurance for specialized trailers/semi-trailers is relevant:
- Transport of bulky or heavy equipment (machinery, tools, agricultural equipment, construction equipment).
- Transport of vehicles (cars, motorcycles, quads…) via car carrier or flatbed.
- Participation in events or competitions — import/export or transport of equipment (motorcycles, quads, rally vehicles, etc.).
- One-off removals, exceptional deliveries, repatriation of goods or merchandise.
- Temporary transport between professionals (e.g. construction site, rental, sale) or between individuals.
In all these cases, the use falls outside a standard framework and the trailer is subject to particular constraints: weight, registration, load, insurance, etc.
3. What obligations and regulations should you be aware of?
- If the trailer has a GVWR ≤ 750 kg , in most cases the insurance of the towing vehicle may suffice — often the civil liability guarantee is sufficient, with a declaration to the insurer.
- If the trailer exceeds 750 kg GVWR , specific mandatory insurance is required — whether for driving or simply parking.
- The trailer (or semi-trailer) must be registered (dedicated registration certificate) and have its own license plate if required by regulations.
- If the trailer is carrying goods, vehicles or equipment, the contents being carried are not always automatically covered by the tractor's car insurance — it is often recommended to choose additional coverages (theft, damage, transport, liability + damage).
4. Guarantees to prioritize for a specialized trailer/semi-trailer
When taking out temporary insurance for this type of equipment, here are the coverages that it is strongly advised to check or include:
- Mandatory civil liability — the legal minimum that covers damage caused to third parties (other vehicles, people, public or private property).
- Material damage / collision / accident — in the event of an accident, the trailer (and its contents) must be able to be repaired or compensated.
- Theft and fire — important if the trailer is carrying valuable equipment or if it is to be parked alone.
- Goods transport / payload — if the trailer is carrying goods, vehicles or equipment, the cover must take the contents into account.
- Assistance / breakdown / towing — useful in case of breakdown, puncture, road incident, especially for semi-trailers or heavy loads.
- Temporary coverage (limited duration) — 1, 3, 7, 30 or 90 days depending on the use: temporary insurance offers the advantage of adapting to a specific need, without long-term commitment.
- Clarity on the hitch and the towing vehicle — the hitch must be declared, the towing vehicle identified, for the insurance to be valid.
5. Points to consider before subscribing
Before approving temporary insurance for a trailer/semi-trailer, pay attention to these points:
- Check the trailer's GVWR to determine if the towing vehicle's insurance is sufficient or if a separate policy is required.
- Declare the hitch to your insurer if the trailer is towed — otherwise the guarantee could be called into question.
- Be clear about the intended use: transport of equipment, goods, vehicle, moving, competition, etc. — this can influence warranties and price.
- Check if the transported contents (equipment, goods, vehicles) are covered, especially in case of theft or damage.
- For professional or intensive use, consider a comprehensive policy rather than just third-party liability.
- Keep all supporting documents: registration certificate, insurance certificate, description of the load, duration, date, towing vehicle — important in case of inspection or accident.
