Any condition requiring medical treatment may itself pose a risk to driving ability if left untreated. Therefore it is important for patients to continue their treatment.
Advice to give to patients:
- it is against the law to drive if your driving ability is impaired by any medicine
- if you are taking your medicine as directed and your driving is not impaired, then you are not breaking the law
- check the leaflet that comes with your medicine for information on how your medicine may affect your driving ability
- do not drive while taking this medicine until you know how it affects you
- do not drive if you feel sleepy, dizzy, unable to concentrate or make decisions, or if you have blurred or double vision
New law on driving having taken certain drugs
A new law on driving after taking certain drugs (including some medicines – see below) is coming into force in March 2015
• This law states that it is an offence to drive with certain drugs above specified levels in the body, whether your driving is impaired or not
• If you are taking these medicines as directed and your driving is not impaired, then you are not breaking the law
• Keep taking your medicines as prescribed
• Check the leaflet that comes with your medicines for information on how your medicines may affect your driving ability
• Do not drive after taking your medicines until you know how they affect you
• Do not drive if you feel drowsy, dizzy, unable to concentrate or make decisions, or if you have blurred or double vision
• If your driving is impaired then you are guilty of breaking the law
What is the issue?
A new law on driving with certain drugs above specified limits in the body is expected to come into force on 2
nd March 2015.1
The list of drugs includes certain medicines that are sometimes abused, such as medicines used to treat:
Dependent upon the approval date of the regulations by Parliament
• extreme pain (morphine, diamorphine, ketamine)
• anxiety or inability to sleep (diazepam, clonazepam, lorazepam, oxazepam, temazepam)
• drug addiction (methadone)
• attention deficit hyperactivity disorder, also known as ADHD (amphetamine)
• multiple sclerosis (nabiximols)
If you are found to be driving with any of these medicines above the limits in your body, you could be guilty of breaking the law. But if you are taking the medicines according to the advice of your prescriber or leaflet in the package, and your driving is not impaired, then you are not guilty of breaking this law.
What will happen if I’m stopped by the police?
The police may use a roadside test to see if you have taken any of the drugs. If the test detects any relevant drugs, the type and level of the drugs in your body can be confirmed by a blood test taken at the police station. The law provides you with a “medical defence”. This states that you are not guilty if:
• the medicine was prescribed, supplied, or sold to you to treat a medical or dental problem, and
• you took the medicine according to the instructions given by the prescriber or the information provided with the medicine.
But if your driving is impaired, you are guilty of breaking the law.
What should I do if I need to take any of the specified medicines?
Keep taking your medicine as prescribed. Check the leaflet that comes with your medicine for information on how your medicine may affect your driving ability. Do not drive while taking your medicine until you know how it affects you. Do not drive if you feel drowsy, dizzy, unable to concentrate or make decisions, or if you have blurred or double vision.
