Combined Offence Of Drink And Drug Driving (NSW)


In New South Wales, it is an offence to drive with a Blood Alcohol Concentration (BAC) reading above the legal limit, as well as driving with an illicit substance present in system, pursuant to section 111A of the Road Transport Act 2013 (NSW). The maximum penalties, in addition to the below disqualification and interlock penalties, are as follows:

Mid-Range Drink Driving with Illicit Substance Present System (First Offence)

A fine of $3,300 and/or 18 months imprisonment.

High-Range Drink Driving with Illicit Substance Present System (First Offence)

Mandatory Interlock Orders for a Combined Offence of Drink and Drug Driving (NSW)

When a person is convicted of a mandatory interlock offence, an alcohol interlock order is automatically imposed unless an exception applies. The interlock order disqualifies the person from driving for a period of time and requires them to then obtain an interlock licence. An interlock device is then installed in their vehicle preventing it from starting if there is alcohol present in the driver’s system.

Unless a person qualifies for an Interlock Exemption Order, a Mandatory Interlock Order will be automatically imposed when they are convicted of this offence. If they are not convicted of the offence, the order will not be made.

If a person is convicted of the offence, they can apply for an exemption from a Mandatory Interlock Order. This should be ideally prepared prior to Court as the application should be dealt with at the same time the sentence is received.

In order for a person to obtain an exemption, they need to satisfy the Court of one of the grounds under section 212 of the Road Transport Act 2013. These are:

  • That they do not have access to a vehicle in which to install an interlock device; or
  • That they have a diagnosed medical condition that prevents them from providing sufficient breath sample and installing the device is not reasonably practical; or
  • If the offence involves a Mid-Range PCA reading only and the matter is the person’s first offence, where an interlock order would cause severe hardship and it is more appropriate in all circumstances not to make an interlock order.

If an exemption order is made, the disqualification periods are much longer than if you are participating in the Interlock Scheme. The information below only applies when you are participating in the Interlock Scheme.
