About Drink Driving Alcohol Limits

In the UK, the current prescribed alcohol limit while driving is 80mg of alcohol in 100ml of blood or 107mg of alcohol in 100ml of urine. Blood or urine samples are usually provided if:

  • The breath testing device at the police station was unavailable, not working or produced an unreliable breath reading
  • You were taken to hospital as you were involved in an accident or experienced medical difficulties at the roadside/police station

Defences for Drink Driving Following Blood or Urine Sample

At JMW, our specialist solicitors make use of a range of defences that help to protect the interests of those accused of drink driving after having to give a blood or urine sample.

Some examples of these kinds of defences include matters relating to:

  • Police procedure - It is surprising how often officers get drink drive procedures wrong by mistakenly following incorrect procedures. Officers must offer you the option of giving a blood or urine sample if you have provided what is known as a 'borderline' breath sample, or the breath testing machine was unavailable or broken
  • Police procedure in hospital - You may have been taken to hospital as a result of an injury or injuries sustained following an accident. Many experienced officers struggle to fully understand the procedures they must legally follow when taking samples from people in hospital. This can, and often does, lead to mistakes
  • Police bail - It normally takes between six and eight weeks for the police to receive confirmation of the blood alcohol reading from the laboratory, but it has been known to sometimes take longer. If you are currently awaiting the result of your blood test, you can still get in touch with us and we can start to lay the foundations of your defence
