Fleet insurance: from how many vehicles, and how does it work?

Fleet insurance becomes available from 3 vehicles with most insurers; some open it from 2 vehicles, others require 4 or 5. It groups all of a company's vehicles under a single contract, with one renewal date, one deductible and one point of contact, and covers in principle any employee authorised to drive. Above the threshold, what really changes is how your premium is calculated: no longer vehicle by vehicle with a no-claims bonus, but on the overall claims record of your fleet.

From how many vehicles do we speak of a motor fleet?

There is no legal threshold. Article L211-1 of the French Insurance Code only requires that every motor vehicle be covered for third-party liability in order to be driven; it says nothing about the number of vehicles that makes a "fleet". The threshold is set by each insurer's underwriting policy. In 2026, offers open between 2 and 5 vehicles: 3 is the most common figure, 4 or 5 are still required by some players, and a few "large fleet" contracts only start at 6 or 10 vehicles.

A motor fleet, in insurance terms, is a set of vehicles owned or leased by the same company and insured under a single contract with common conditions. The contract covers the vehicles, not named drivers, which allows any licensed employee to take the wheel without an individual declaration. Cars, vans, heavy goods vehicles and two-wheelers can all be included.

How does a company fleet insurance contract work?

The principle is that of a framework contract. At inception you declare the list of your vehicles (registration, category, use, value) and the insurer issues a single contract with a "fleet schedule". Cover is defined by category: vans on comprehensive, executive cars on extended third-party, without multiplying contracts. Three mechanisms distinguish a fleet from a sum of individual policies: a single renewal date, which simplifies competitive tendering; harmonised deductibles and limits per category; and an open-driver clause, which authorises any employee, temp or intern mandated by the company to drive, subject to the age or licence-seniority conditions set out in the contract.

Since 1 April 2024, the green card has been abolished in France: proof of insurance now rests on the Insured Vehicles File (FVA), which the police consult directly. A vehicle that has been delivered but not yet declared to the insurer therefore shows up as uninsured at a roadside check.

How do you manage vehicles joining and leaving the fleet during the year?

This is the real value of a fleet contract for a growing company. Under "endorsement" management, each addition or removal is declared and priced pro rata. Under "periodic declaration" management, more common above 20 or 30 vehicles, you send the fleet schedule at regular intervals and the premium is adjusted at year end.

An endorsement is the document that amends an insurance contract during its life: it adds or removes a vehicle, changes a cover or a deductible, and takes effect on the agreed date without cancelling the contract. Most insurers automatically cover incoming vehicles for a short period, often 15 to 30 days, provided the declaration follows. That window is what protects you between delivery of a vehicle and its declaration: check it.

A fleet is not insured like three cars: you no longer buy a rate per vehicle, you negotiate the price of a global risk whose claims history is the first argument.

Why does the no-claims bonus not apply to a fleet?

The bonus-malus clause is the regulatory mechanism (annex to Article A121-1 of the Insurance Code) that varies a vehicle's premium according to at-fault claims in previous years: −5% per claim-free year, +25% per at-fault claim. It does not apply to vehicles insured under a company fleet policy.

Instead, the insurer steers the premium on your loss experience, i.e. the ratio between the claims it has paid and the premiums you have paid (the loss ratio). For a fleet of 3 to 20 vehicles, the rate is loaded or discounted at each renewal according to claims frequency. Above a few dozen vehicles, the fleet becomes "rated": the insurer analyses three to five years of history and rebuilds the rate. A clean claims record is therefore worth several thousand euros when you go out to tender.

How much does fleet insurance cost in 2026?

Price is reasoned per vehicle per year, and it falls with fleet size. For ordinary cars and vans, ranges observed in 2026 run from €350 to €1,200 per vehicle, outside high-risk sectors. Transport, delivery and construction carry loadings of 15% to 50%, and the Paris region costs 10% to 25% more than the provinces.

The 2026 context is more favourable than 2023 and 2024. After annual increases of 7% to 8%, the January 2026 renewals were completed, according to specialist brokers, with contained increases of 3% to 5%, despite repair costs up nearly 30% in five years. Insurers have put prevention back at the centre: training, telematics and driver monitoring deliver an average 15% reduction in claims costs from the first year, which flows through to the rate. The levers detailed in our 10 ways to reduce a business insurance premium apply fully to fleets.

What does a company risk if one of its vehicles is uninsured?

Driving without insurance is a criminal offence under Article L324-2 of the French Highway Code, punishable by a €3,750 fine, raised to €7,500 for repeat offences, with possible licence suspension, immobilisation or confiscation of the vehicle. For the company, the real risk lies elsewhere: after a bodily-injury accident caused by an uninsured vehicle, the French guarantee fund for compulsory insurance (FGAO) compensates the victims and then recovers the full amount from the vehicle's owner.

Road risk is the leading cause of work-related death in France: according to key figures published by the Ministry of Labour, the national health insurance fund and the road safety observatory ONISR, 485 people were killed in work-related journeys in 2022. A business-trip accident is also a workplace accident, with consequences for your occupational-injury contribution rate.

Are employees who drive their own car for work covered?

Rarely, and this is the most common blind spot. An employee's personal car policy covers commuting but generally excludes professional use: a sales rep visiting clients in their own car, without a use extension, is poorly insured, and the employer who sent them is liable.

Business-use cover for personal vehicles ("auto-mission" insurance) is a policy taken out by the company to cover its employees' own cars when used for a business trip requested by the employer. It provides third-party liability on top of the employee's contract, often damage to the vehicle, and spares the employee from losing their no-claims bonus after an accident on company business. A services SME with no fleet, but twenty staff who visit clients, needs it more than a fleet in the strict sense.

Frequently asked questions

Do drivers have to be declared under a fleet insurance policy?

No, in the vast majority of contracts: the fleet covers vehicles, not named drivers, so any employee with a valid licence may drive. The contract may set age or licence-seniority conditions and a higher deductible for young drivers.

Can cars, vans and trucks be mixed in the same fleet?

Yes. A fleet contract is designed for heterogeneous vehicles, each attached to a rating category with its own cover and deductibles. Long-term leased vehicles can be included if the lessor agrees, which avoids the insurance bundled into the lease, often more expensive.

What happens if I fall below the vehicle threshold during the year?

The contract runs to its renewal date; at renewal, the insurer may propose a return to individual policies or continuation as a fleet on revised terms.

Does fleet insurance cover goods and equipment being carried?

Not by default. The fleet covers the vehicle and liability arising from its use; goods, tools and equipment carried fall under a specific extension or your commercial property policy. A transport and logistics company must also hold separate carrier's liability insurance.
