Alcohol Interlock
AF-i1
Equipped with a premium electrochemical sensor (fuel cell sensor), the ALCOFIND AF-i1 is an alcohol interlock installed in the vehicle. It checks the driver's BAC and prevents the engine from starting if it exceeds a set limit, stopping drunk driving at the source. It is currently used in government programs in major European countries including Sweden, Norway, Finland and France.
