In Italy, regulations mandating the installation of alcohol interlock devices in vehicles owned by individuals convicted of drunk driving came into force on February 24, 2026. The device, which prevents the engine from starting after detecting alcohol in the driver's breath, costs around 2,000 euros. The Ministry of Transport has published a list of authorized devices and installers, although Federcarrozzieri points out that not all car models can be equipped with them.

Obligation for Convicted Drivers

An alcohol interlock will become mandatory for individuals convicted of driving under the influence. The installation aims to prevent recidivism.

High Device Cost

The cost of purchasing and installing the alcohol interlock is estimated at around 2,000 euros, representing a significant financial burden.

Penalties for Tampering

Attempts to manipulate or destroy the seals on the device will result in double penalties. This also affects other users of the vehicle.

Technical Limitations

According to a statement from Federcarrozzieri, not all vehicle models will be able to be equipped with the approved alcohol interlock system.

From February 24, 2026, a regulation comes into effect in Italy imposing an obligation on those convicted of drunk driving to install an alcohol interlock device in their vehicle. This device, connected to the ignition system, requires the driver to pass a breathalyzer test before starting the engine. If the alcohol level in the exhaled breath exceeds the permissible limit, the lock will prevent driving. The Ministry of Transport has already published an official list of approved devices and authorized installation points. The fight against drunk drivers has been a road safety priority in many European countries for decades. The first experiments with mandatory alcohol interlocks for repeat offenders began in Scandinavia in the 1990s, and similar programs now operate in countries including Belgium, France, and the Netherlands. In Poland, the concept of mandatory alcohol interlocks for perpetrators of serious alcohol-related accidents is regularly discussed but has not yet been implemented. The new Italian regulations involve a significant cost for the driver. The purchase and installation of the device is estimated to be an expense of around 2,000 euros.
