Random roadside drug testing

What drugs will be tested?

Police will ask you to provide a saliva sample for the purpose of testing for:

• THC—the active ingredient in cannabis

• Methylamphetamine—also known as speed and ice

• MDMA—the active ingredient in ecstasy.

Saliva tests will only be able to detect the active ingredients of the nominated drugs THC, MDMA and methylamphetamine.
Even though methamphetamine is manufactured from substances such as pseudoephedrine (found in cold and flu tablets) those substances will not be detected by the saliva tests.

How will saliva based roadside drug driving testing work?

Roadside drug testing allows police to conduct saliva testing in conjunction with random breath testing (RBT) or as a stand alone check. The roadside drug testing process operates in a similar way to RBTs.

What is the testing process?

You will undergo a simple and painless preliminary saliva test (screening test) which will take three to five minutes. If a negative result is returned you will be free to go. If a positive result (drug detected) is returned you will be taken to a police vehicle for a second saliva test.

If the second saliva test is positive for drugs, your driver licence will be suspended for 24 hours and the remainder of the saliva sample will be sent for laboratory analysis. Following a positive laboratory result, motorists will be notified and charged with a traffic offence for drug driving.
If you are unable to provide a saliva sample you will be required to provide a specimen of blood for analysis.

What level of drugs can be detected without penalty?

There will be zero tolerance. Any trace of the nominated drugs in your system and you can be penalised.

What are the penalties?

A first offence carries a penalty of up to $1649 and you could be disqualified from driving for up to 3 months. Any subsequent offences can carry higher penalties and driver licence suspensions prior to appearances in court.

Can a saliva sample be used for other purposes?

No. Saliva samples obtained from a roadside drug test can only be used to detect drug driving and will only result in a traffic offence if a positive result is returned.
All saliva specimens obtained from roadside drug testing will be destroyed once they are no longer required.

Who will conduct the test?

Police officers who are trained and authorised to operate the testing devices will conduct roadside drug testing.

How long after consuming illegal drugs can they be detected?

The saliva tests are designed to only react with the active ingredient of the relevant drug.
The detection period for the active ingredient in the relevant drug varies depending on factors such as the quantity and quality of the drug that has been ingested, the frequency of use of the drug and the period of time since taking the drug.

Prescription and other drugs

Driving under the influence of drugs

If a police officer reasonably suspects that your driving ability has been impaired by any drug you may be required to provide a specimen of blood for analysis.
If you fail to provide a specimen as required, or a drug is detected in your blood, you will be charged and required to appear in court. If convicted you could be disqualified from holding or obtaining a driver licence for a period of time. You may also be fined and face jail time.
