Police have the right to pull over a driver at any time and conduct a drug test.

In Victoria, it’s illegal to refuse a random roadside drug test, this can result in major penalties including fines, license cancellation (min 2 years) and imprisonment (depending on prior offences).

Many drugs (including prescription and illicit) can impair your ability to drive. If you use drugs, it’s good to know how long they stay in your system so you can keep yourself and your mates safe on the roads.

What happens at a roadside drug test?

‍

• You'll be asked to show your drivers licence
• You’ll be asked to provide a saliva sample – via a tongue swab
• Police will analyse the sample – it’ll take a few minutes
• If the sample is negative, you can go on your way
• If it’s positive, you’ll be asked to provide a second sample which is sent to a laboratory for testing. A positive laboratory test could result in a drug driving charge.
• Police may also do an impairment assessment test to check your coordination and balance.
  
• Blood and urine tests can also be requested if drug driving is suspected.
