The family of a man who was killed by a driver high on drugs and alcohol out on bail have sent a letter to the government calling for the use of roadside saliva drug-tests to take dangerous drivers off the road.

Linzi Stewart, 49, has written to the Home Office to update legislation to allow roadside saliva samples to be used as evidence to prosecute drug drivers and take them off the road - rather than having to wait for a blood sample to be processed.
