If police stop you, they can do a preliminary assessment of physical factors such as your behaviour, balance and coordination. If this assessment shows that you may be impaired by a drug, you will need to give blood and/or urine samples.
You will be given a penalty if you are found guilty of drug-driving. There are different penalties depending on whether it is your first offence or if you have been caught before. The following table explains the different penalties.
The value of a penalty unit changes each financial year and is published on the Department of Justice and Regulation website.
The value of a fine is the value of the penalty unit multiplied by the number of penalty units for the offence.
