Drink Driving

  • What are the legal limits?
    The current limits are:

    • 35 microgrammes of alcohol in 100 millilitres of breath
    • 80 milligrammes of alcohol in 100 millilitres of blood
    • 107 milligrammes of alcohol in 100 millilitres of urine
  • How is drink driving tested?
    If the police have reasonable cause to believe you have been drink driving, you will be given a roadside breath test. If you fail, evidence of the alcohol level will need to be gathered at the police station, via a breath, blood or urine specimen.
  • Why do I need to give further specimens?
    The roadside test is just an indicator of whether you are over the limit. Actual evidence that can be used in court will need to be gathered on the machines at the police station.
  • What happens after the reading has been taken?
    If the reading is 39 microgrammes or below, you will be released with a warning. For readings between 40 and 50 microgrammes, you should be offered the option of a blood or urine test. The blood sample will need to be taken by a police surgeon. If you are still over the limit, you will be charged.
