Is it an offence to drive or attempt to drive while unfit through medicine?

It is an offence to drive or attempt to drive while unfit through drugs, and the law does not distinguish between illegal drugs and medicines. A person who, when driving or attempting to drive, or in charge of, a mechanically propelled vehicle on a road or other public place, is unfit to drive through drink or drugs is guilty of an offence.

This law exists because a driver who is impaired through drugs is at risk of having an accident. Insurance will be affected by a conviction or an accident linked to drugs and medicines in the same way as it is for drink-driving.
