In France, car insurance premiums have been steadily increasing for several years, due to the combined effects of rising repair costs and the revaluation of the insurance tax. Between 2021 and 2025, the price of spare parts and onboard electronics has significantly raised the costs of repairs after a collision. Choosing a suitable contract requires a trade-off between monthly contributions, deductible levels, and the actual scope of coverage.
Deductible and premium: the trade-off that simulators do not make for you
Most online comparators rank offers by annual contribution price. This sorting obscures a crucial parameter: the deductible, which is the amount you are responsible for after a claim.
With the rising cost of repairs, a low deductible offers better protection but costs more in premium. Conversely, a high deductible reduces the contribution but exposes you to a significant out-of-pocket expense in the event of a collision or glass breakage. For a recent vehicle valued at several tens of thousands of euros, the difference can represent several hundred euros on a single claim.
The most reliable method is to compare offers with equivalent coverage, then calculate the total cost based on a concrete scenario: annual premium multiplied by three years, plus a deductible for a responsible claim. This simple calculation often reveals that the cheapest contract at subscription is not the least expensive in use.
Among the platforms that facilitate this comparison, the insurance offered on Car Only allows you to visualize coverage and deductibles side by side before committing.
Comprehensive or third-party car insurance: what each formula really covers
The distinction between third-party insurance and comprehensive insurance seems clear in theory. In practice, the scope varies from one insurer to another, and some coverages that one might assume are included in a comprehensive contract are not always guaranteed.
What third-party covers and what it excludes
Third-party insurance, mandatory in France, covers civil liability: damages you cause to another vehicle, a pedestrian, or property. It does not cover damages to your own car, theft, or fire.
For an older vehicle with a low replacement value, this formula may suffice. The savings made on the premium compensate for the risk of having to finance a repair or replacement yourself.
The gray areas of comprehensive insurance
A comprehensive contract generally includes collision damage coverage, theft, fire, and glass breakage. Some insurers add natural disaster coverage or legal protection.
Fire coverage is not always included in the basic formula of some contracts presented as “comprehensive.” Similarly, coverage for the contents of the vehicle (personal items stolen from the cabin) often requires a paid option. Reading the specific terms remains the only way to verify what is actually covered.
- Check if the theft coverage includes car-jacking (theft with violence) or only burglary.
- Verify the compensation limit in case of total loss of the vehicle: some contracts apply a rapid depreciation starting from the second year.
- Look to see if breakdown and accident assistance operates near your home (often excluded below 25 or 50 kilometers).
Bonus-malus coefficient: how it affects contract choice
The bonus-malus system, applied by all insurers, starts with a coefficient of 1. Each year without a responsible claim, this coefficient is multiplied by 0.95. In the event of a responsible accident, it is multiplied by 1.25 (or by 1.125 for a partially responsible claim).
A driver without a claim for thirteen years reaches the maximum bonus of 0.50, which is a 50% reduction on the reference premium. Conversely, a single responsible accident erases several years of accumulated bonus.
For drivers with a malus or those canceled by their previous insurer, options are limited. Specialized contracts exist, but their premiums are significantly higher. In this situation, it may be relevant to temporarily accept a high deductible to limit the contribution, then renegotiate after two or three years without a claim.
Electric vehicle: specific clauses to check
Car insurance contracts for electric vehicles follow the same structures as those for thermal vehicles, with some particularities related to the battery and range.
Assistance in case of a dead battery is the most discriminating factor among the offers. Not all contracts provide for towing to a charging station. Some limit this assistance to a minimum distance from home, which can be problematic on a long trip.
The coverage of the battery itself deserves attention. In an electric vehicle, the battery represents a significant part of the total value. Check if the contract covers accidental damage to the battery, and if the charging cables are included in theft or breakage coverage.
- Ask if towing to a charging station is included, and within what geographical radius.
- Verify coverage near home, often excluded in standard contracts.
- Check if the battery is covered at replacement value or at market value after depreciation.
The insurance tax, which recently increased from 6% to 9% for car contracts according to the decree of December 22, 2023, also applies to electric vehicles. This three-point increase can represent several tens of euros per year without any changes to the coverage. It is a line item to identify on the renewal notice to distinguish a tax increase from a pricing decision by the insurer.
The choice of car insurance relies on concrete parameters: vehicle value, driving history, annual mileage, type of engine. Comparing offers with equivalent coverage and deductibles, rather than just the displayed price, remains the most reliable method to manage your budget without discovering an unpleasant surprise at the first claim.
