A text designed to provide the general practitioner with basic information required in road traffic cases, this book is one of a series presenting practical information on mainstream legal topics. It guides the reader through common legal procedures with the aid of checklists, tables and charts. This book also gives tables of principal traffic offences, summarizes common offences, and provides the means to understand the relative levels of blood, breath and urine, and how to back calculate. Each book in the series details relevant costs, fees and time limits, lists selected precedents, highlights everyday problems and offers solutions, and indicates where to find more detailed coverage of particular points. Case studies and statutory references are also included. The series complements the "Practitioner Series" by including cross-references from each Practice Note to the "Practitioner Series" for more detailed coverage of the law.
