Factsheet: Random alcohol and drug testing

How is the test carried out?  

For a random breath test, the police will ask you to either blow, count or speak into a machine.  

For a drug test, you will be asked to wipe a test stick down your tongue. The results will usually take a few minutes. 

You have to wait until any test is clear and police confirm this, before driving away.

What drugs will the drug test pick up? 

Drug tests can pick up ecstasy, cannabis, cocaine and methamphetamine (including speed and ice).  

Your prescription medicine may mean you test positive for these substances. If you are taking prescription medicine, talk to your doctor about whether it is safe to drive while taking the medicine. You should keep a copy of the prescription or box of the prescription medicine in your car, to show the police if you test positive.
