Rule change: drugs and medicine
Rule 96 of The Highway Code has been updated 2 March 2015.
|New rule 96 wording|
You MUST NOT drive under the influence of drugs or medicine. For medicines, check with your doctor or pharmacist and do not drive if you are advised that you may be impaired.
You MUST NOT drive if you have illegal drugs or certain medicines in your blood above specified limits. It is highly dangerous so never take illegal drugs if you intend to drive; the effects are unpredictable, but can be even more severe than alcohol and result in fatal or serious road crashes. Illegal drugs have been specified at very low levels so even small amounts of use could be above the specified limits. The limits for certain medicines have been specified at higher levels, above the levels generally found in the blood of patients who have taken normal therapeutic doses. If you are found to have a concentration of a drug above its specified limit in your blood because you have been prescribed or legitimately supplied a particularly high dose of medicine, then you can raise a statutory medical defence, provided your driving was not impaired by the medicine you are taking.
