Buying a Used Car With a Black Box: 2026 Guide

Two different black boxes, and that is where the confusion starts

In Italy, two unrelated devices both go by the name scatola nera. The first is the EDR, the Event Data Recorder, mandatory since 7 July 2024 on every newly type-approved car: it logs a few seconds of speed, braking and acceleration only around a crash, stays permanently fitted, and has nothing to do with any insurer [3]. The second is the actual insurance black box, the one an insurer offers in exchange for a discount on liability cover: it is a removable device, owned by the insurer or its telematics provider, and it continuously tracks mileage, time of day and driving style for as long as the policy runs [2]. When someone buys a used car, it is almost always the second one that raises questions: what happens to the device, the data it collected, and the discount once the registration changes hands?

Why it still pays off, and by how much

The numbers still favour installing one. A 2022 report from IVASS, Italy's insurance regulator, found that a black box brings an average 10% saving at renewal, while drivers who switch insurer at the end of the year can land a better price, in a range between 12% and 19% [1]. Adoption backs this up: since 2012 the number of policies bundled with a black box has grown by 300%, and the latest available data put the national share at roughly one in five RC auto policies, up from just over 16% the year before [6][8].

The regional gap is enormous

Italy does not use black boxes evenly. In the provinces of Naples and Caserta, adoption tops 50%, essentially one insured car in two. In Campania, Sicily, Calabria and Puglia the share stays above 20%, while in Trentino-Alto Adige, Friuli Venezia Giulia, Veneto and Valle d'Aosta it drops to between 4.4% and 7.2% [6]. The driver is almost always the starting cost of liability insurance itself: where premiums are higher because of more claims, a black box discount matters more to the decision. That is useful context for a buyer, too - a used car coming from the south is far more likely to already have one fitted than a car coming from the north-east.

Law 193/2024 changed the rules, but not the ones people assume

The real legal shift came with the Competition Decree, which became Law No. 193/2024 on 16 December 2024. Before that, a black box created a lock-in effect: IVASS had already flagged in 2022 that it cut the probability of switching insurer by 60%, because moving to a new company meant losing the accumulated driving history and paying to have the old device removed [4]. The law introduced data portability: a policyholder can now ask their insurer for total mileage, mileage broken down by road type, daytime and nighttime usage, and high-speed driving events from the last twelve months, in a free, machine-readable format, so it can be carried to a new insurer. Clauses that blocked free removal of the device at the annual contract renewal were also banned outright [4][5].

The key detail is that these rights belong to the policyholder, not the vehicle. Switching insurer while keeping the same car and the same owner is now much easier. Switching the owner of the car is a completely different matter.

What actually happens when a car changes hands

In Italy, liability insurance is tied to the person, not the vehicle: when a car is sold, the seller's policy does not automatically transfer to the new owner. It has to be suspended or cancelled, with a refund of the unused premium, net of taxes and national health contributions, if the contract allows for it [7]. The buyer has to take out a brand-new policy in their own name. That has two very concrete consequences for anyone buying a used car:

• The clean driving history built up by the previous owner does not transfer to the buyer. That record stays the previous owner's property and can only follow them to a policy in their own name, never to the new buyer's policy.
• If the seller's physical device is still fitted to the car, it does not automatically unlock any discount. The buyer needs a fresh policy with a black box activated in their own name, often a different device supplied by their new insurer.

There is a privacy upside here too: a used-car buyer does not inherit anyone else's driving history, good or bad.

A practical checklist for sellers and buyers

For sellers: before the ownership transfer, ask the insurer whether the device needs to be removed or can stay in place inactive, and confirm whether removal is free (usually only guaranteed at the annual renewal date) or comes with a fee for an early cancellation triggered by the sale.

For buyers: never assume a discount comes bundled with a device already in the car. Always ask the seller whether the previous black box was removed or is simply dormant, and weigh taking out a policy with your own black box to earn the discount from scratch, especially if the car comes from a low-claims region where adoption is lower but the saving is just as real.

No discount ships pre-installed with the car. It always has to be requested and activated through your own insurer, regardless of what the previous owner did.
