A Review of Methodologies Employed in Roadside Surveys of Drinking and Driving

This report reviews roadside surveys previously conducted in the UK, and considers similar studies conducted in other parts of the world, with the primary objective of identifying examples of best practice which could inform the design of a new drink drive UK roadside survey.

The report addresses the following questions:
• What methodologies have been used in previous roadside surveys undertaken by
the UK?
• What can we learn from the approaches taken in previous research?
• Are there any limitations with the methods used in the previous work?
• How does the approach taken in the UK compare with approaches taken by other
countries: for example, in other European countries and in North America?
• What evidence exists for the appropriateness and effectiveness of the UK
approach and alternatives identified elsewhere?
• What lessons can be learned from these alternative approaches?
• What improvements could be made to the UK approach?
• Based on the evidence from the UK and overseas, what options/
recommendations are there for the UK?
