Alcohol Interlocks in Italy

In 2020, a legal proposal to introduce alcohol interlocks came from the CNEL (The National Council for Economics and Labor), a state body with the power to propose new legislation, and has been presented to the House of Representatives of the Italian Parliament, marking the first step on the road to adoption. The Alcohol Interlock programme for drink-driving offenders was adopted in December 2024 and came into force in July 2025. 

In the new law, recidivists offenders driving with a BAC from 0.8 g/l to 1.5 g/l will have to install an alcohol interlock for 2 years (following a driving ban of 6 up to one year) and 3 years if they are caught with a BAC above 1.5 g/l (following a driving ban of one up to two years). 

Sanctions for not complying with the installation of the device can go from 158 up to 638 euros, as well as a licence suspension of 1 to 6 months. Penalties can double in case the device has been circumvented. Finally, all penalties will be increased by a third if the convicted driver has not installed the alcohol interlock and is caught again under the influence of alcohol.
