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

Drink driving

  • Around 1 in 9 motor vehicle drivers killed in traffic collisions were over the drink-drive limit.
  • Around 1 in 12 motorcycle riders killed were over the drink drive limit.
  • In 2012, there were 117 accidents where the reporting police officer considered that a pedestrian(s) being ‘impaired by alcohol’ was a contributory factor to that accident.

Drug driving

  • For every 7 accidents where the driver was impaired by alcohol, there was around 1 accident where he/she was ‘impaired by drugs’, both illegal and medicinal.

Breath tests of drivers taken after accidents

  • No marked seasonal pattern in casualties over a year arising from accidents where one or more of the drivers involved tested positive.
  • More drivers in accidents test positive on the weekend rather than a weekday, and that they are more likely to test positive after traditional working hours, between 16:00 to 04:00.
