An annual report which presents information about association between drink driving and accidents, results of breath tests of drivers involved in accidents and enforcement action relating to drink driving.

Key points

  • In 2015, 6 per cent of all drivers of motorised vehicles and 8 per cent of motorcyclist drivers/riders killed in traffic collisions were above the drink drive limit.
  • The Department of Transport (DfT) report that 8 per cent of killed or serious injury accidents (KSI) that occurred in Wales in 2015 involved drivers over the blood alcohol limit.
  • In terms of road accidents, police officers’ views about the contributory factors that led to accidents suggested that 9 per cent of KSI accidents during 2016 involved drivers that were impaired by alcohol.
  • In 2016, 66 accidents where the reporting police officer identified pedestrian(s) being impaired by alcohol as a contributory factor to that accident.
  • In 2016, there were approximately 3.5 accidents where the driver was impaired by alcohol, for every 1 accident where a driver was impaired by drugs.

Breath tests of drivers taken after accidents show:

  • considerable variation between the months of the year and the same months in different years with a 10.3 per cent reduction in positive tests observed when compared to the 2015(r) data
  • drivers were more likely to test positive at the weekend than on a weekday (4.6 vs 2.8(r))
  • 64.5 per cent of positive tests, for drivers, occurred between 18:00 to 03:59.
