New ways to use biochemical indicators of alcohol abuse to regrant licences in a fairer manner after drunken driving in Germany.

The failure of medical-psychological examination to provide convincing recommendations concerning the regranting of licences in a significant number of cases illustrates the need for objective laboratory testing. Experience in Germany shows that blood-alcohol concentration alone could lead to misleading recommendations, and suggests that laboratory testing is best done on samples taken at the time of the offence, rather than subsequently at medical-psychological investigation.
