Abstract
A Breath Alcohol Ignition Interlock Device (BAIID) is a breath testing device connected to the ignition system of a motor vehicle. It prevents an operator from starting the vehicle if the breath alcohol concentration (BrAC) exceeds a predetermined threshold or fail level. From November 2000 until September 2001, a consortium of European road safety research institutes conducted a feasibility study regarding the implementation of BAIIDs in EU drink-driving policies. This is the final report of the feasibility study. (A)
