'This book shows how the road traffic law is applied in practice - providing a historical, moral and legal argument for the difficulties in dealing with driving offences and proving intent. The book also draws on psychological theories about the defendant's "state of mind" at the time of the offence and sheds light on a hotly debated societal problem - why thousands of people are killed and injured globally yet very few prosecutions result. It is a valuable contribution to the field.' Lisa Dorn, Cranfield University, UK
