TRUCK AND TRAILER INSURANCE
Questions to ask before you tow, park or hire a trailer
Check the towing vehicle, trailer and goods separately. Tell your broker who owns the trailer, how it is used and where it is kept, then ask them to confirm the cover in writing.
This guide is for UK truck owners and operators. It explains questions to ask about a policy; it does not confirm that a particular broker or insurer offers the cover described.
Does truck insurance cover the trailer?
Do not assume that insuring the tractor unit or rigid truck answers every trailer question. Ask the broker to identify the trailer provisions in the schedule, wording and endorsements, including any requirement to list individual trailers. Check damage to the trailer and liability to other people separately.
For example, Intact’s April 2026 motor fleet wording (PDF, section 10) distinguishes specified and undeclared trailers, attached and detached use, and damage and liability cover. It also sets out trailer exclusions and excesses. That is an example of why the detail matters, not a description of every policy or a recommendation of that insurer.
Attached, detached and stored trailers
Describe what happens between journeys as well as on the road. A trailer may be coupled to a truck, left at a customer’s premises, parked in your yard or held elsewhere for repair. Ask:
- What cover applies in each of those situations?
- Are accidental damage, fire and theft included, and what limits apply?
- Does detaching the trailer change the cover, excess or security requirements?
- Must the trailer be listed individually, and how do I notify a change?
Hired, borrowed and interchanged trailers
Give the broker the hire or interchange agreement and explain who owns the trailer, who uses it and who is responsible for insuring it. Ask them to compare your contractual responsibilities with the actual policy cover. Do not rely on a verbal assurance that the owner has insurance.
- Does the policy accept this ownership or hire arrangement?
- Are there conditions when another operator uses my trailer or I use theirs?
- What happens if the hire agreement makes me responsible for loss of use, recovery charges or other costs?
- Is trailer-only insurance needed or available if there is no towing vehicle on the same policy?
Parking, security and theft
Describe the overnight location, access controls and any locks, immobilisers or tracking equipment. Ask which measures are policy conditions, when they must be used and what records are needed. Confirm how to report a change of storage location or an extended period out of use.
The load and fitted equipment
Ask about the trailer itself, its equipment and the goods it carries as separate items. Identify cranes, lifting gear, refrigeration units and other fittings, with their values and uses.
- Where is damage to fitted equipment covered?
- Are goods in transit insured separately, and for which loads and values?
- How are loading, unloading, equipment failure, temperature changes and spoiled goods treated?
- What exclusions or evidence requirements apply to each section?
Use the flatbed truck guide for open loads and fitted cranes, or the refrigerated truck guide for temperature-controlled work.
Excesses, claims and overseas work
Ask what excess applies if the truck and trailer are damaged in the same incident, and whether detached theft has different terms. Record whom to contact, when an incident must be reported, what evidence is required and who must authorise recovery or repairs.
For overseas journeys, give the broker the countries, dates and work involved. Ask them to confirm the territorial cover for both truck and trailer. Separately check the applicable registration, licensing and travel-document requirements; an insurance quotation does not establish compliance with those rules.
Details to take to the broker
- Truck and trailer identification, type, weight and value.
- Ownership, finance, hire or interchange agreements.
- Drivers, work, loads, routes and any overseas journeys.
- Fitted equipment and its use.
- Attached and detached use, parking locations and security.
- Claims history and the required cover dates.
Keep the broker’s answers with the final policy documents. Before using the combination in reliance on cover, obtain confirmation that the relevant vehicles, trailers and activities are accepted and when the cover begins.
