New drug drive legislation comes into force from 2 March 2015 in England and Wales. For drugs associated with illegal use, very low limits have been set (to cover ‘accidental’ exposure). But for the following eight prescription drugs, limits that exceed the prescribed dose have been set:

  • Clonazepam
  • Diazepam
  • Flunitrazepam
  • Lorazepam
  • Oxazepam
  • Temazepam
  • Methadone
  • Morphine

The higher limits are applied as long as they are being taken in accordance with the advice of a healthcare professional and driving/riding is not impaired as a result. If so, you will not be at risk of arrest (but make sure you have evidence such as a prescription).
