The EDT is assessed in the same way as the standard test, but lasts approximately 70 minutes, compared with 40 minutes for a standard test.
The current offences for which an EDT is mandatory are:
• Motor manslaughter
• Causing death by dangerous driving
• Causing serious injury by dangerous driving (from 2012)
• Dangerous driving
• Causing death by careless driving under the influence of drink or drugs
The research aimed to investigate the use of EDTs in courts, and the number and characteristics of offenders who are ordered to take an EDT or standard test for different offences, together with other penalties and re-offending.
