What is drug driving?

Drug driving is being caught driving or attempting to drive a vehicle while under the influence of drugs, including illegal, legal or prescribed. It is illegal to drive if either you are unfit to do so due to being under the influence of illegal or legal drugs, or if you have certain levels of illegal drugs in your blood even if they haven’t affected your driving.

The police can stop you and carry out an impairment test at the roadside to assess whether your driving ability has been hindered by taking drugs and they will then take a blood test as soon as they can. A roadside drug kit can now be used by the police to screen for cannabis and cocaine.

There are also specific limits set for a number of drugs, both legal and prescribed. You will be committing an offence if you are found to be over the prescribed limit for these drugs even if you believe that your driving was not impaired. A table of these limits can be found here.

Prescribed drugs and medicine from a doctor or similar medical professional can also hinder your driving performance. While it is always best to check whether you are able to drive while on prescription medication, there are legal limits in place for certain substances. These are measured per litre of blood and include:

  • Benzoylecgonine - 50 µg/L
  • Clonazepam - 50 µg/L
  • Diazepam - 550 µg/L
  • Lorazepam - 100 µg/L
  • Methadone - 500 µg/L
  • Morphine - 80 µg/L
  • Oxazepam - 300 µg/L
  • Temazepam - 1000 µg/L

Should you be driving while taking prescribed medication, ensure you keep any proof that it is your medicine to show to police if you are stopped.

The penalties

Like drink driving, the penalties for driving under the influence of drugs can have far-reaching effects. Penalties include:

  • Disqualification from driving for a minimum of 12 months
  • Prison sentence of up to six months
  • An unlimited fine

In turn, the consequences of this often include:

  • Job loss
  • Loss of independence
  • Shame of having a criminal conviction
  • Trouble of getting into countries like the USA
  • Massive increase in car insurance costs, and some companies won’t insure you

    I would just like to write a few lines on the service I have received. From the very outset, Meghan helped put me more at ease, by explaining the process in simple terms of which before, seemed like a very daunting task. She was very calm and professional during my interview, which helped as the policeman had little understanding of how the law works in these situations. Meghan looked through the case and really helped me through the next steps towards the court. I received very good advice at court. Meghan's knowledge of the law helped me achieve the result I needed to retain my license and be able to carry on with my busy life. My family, staff and I will be forever grateful, and I would not hesitate to recommend Meghan Waldron and Lupton Fawcett in the future.
