Safe driving requires good judgement and sharp concentration. You also need to react quickly to changing situations on the road. Drug driving puts everyone on the road at risk. NSW research shows that the presence of?illegal drugs is?now involved in more fatal crashes than drink driving. Mobile Drug Testing (MDT) has been introduced to operate alongside Random Breath Testing (RBT) for alcohol by police in NSW. MDT detects drivers who have recently used three common illegal drugs: ecstasy, cannabis and speed (including ice). A test for cocaine is being planned soon because of concerns about its increasing use.

The roadside tests involve a saliva test. If the initial saliva test indicates positive, then the driver must undertake a second saliva swab at a mobile drug bus or police station. http://roadsafety.transport.nsw.gov.au/stayingsafe/alcoholdrugs/drugdriving/index.html
