Why should you use BS EN 50436-3 - Alcohol interlocks — Guidance?
An alcohol interlock is a system comprising a breath alcohol measuring instrument and an immobilizer that may be easily installed in motor vehicles like passenger cars, coaches, taxis, hazardous goods transporters, lorries, trams, trains, motorcycles, boats, or snowmobiles. Before the vehicle motor can be started or the vehicle can be moved, a breath sample needs to be provided to the alcohol interlock, normally through a mouthpiece. Once the breath alcohol measurement has been performed, the alcohol interlock will prevent drivers from starting the motor if they have an alcohol concentration above a predetermined limit value. This limit may be set at the legal limit of a respective country or lower.
BS EN 50436-3 describes alcohol interlocks for use in vehicles as a general preventive measure in traffic safety as well as for use in drink driving offender programmes. However, the information provided may also be useful for alcohol interlocks in other applications.
Briefly, BS EN 50436-3 will help you with using an alcohol interlock device.
