The objectives of this study were to review the evidence on the effectiveness of random breath testing and to identify possible characteristics of a 'best practice' approach to its implementation. A literature review was conducted to find relevant material, and interviews were conducted with key road safety stakeholders with expertise in the fields of drink driving and random breath testing. The literature review found that studies evaluating the effectiveness of random breath testing had only sometimes found it to be effective in reducing road crashes and injuries. Methodological difficulties encountered in conducting the evaluations included having to rely on statistical methods to test the relationship between random breath testing and road crashes rather than using effective research design, and limitations in the availability of appropriate crash data.
