The State Government’s promise to get tough with drink drivers starts on Monday October 24th, when new alcohol interlock laws come into force.

High end and repeat drink drivers will be required to install an alcohol interlock in their vehicle, if convicted of one of the following offences:

  • Any Driving under the influence of alcohol offence (BAC of 0.15 or more),

  • Any dangerous driving causing death/injury offence where DUI is an element,

  • Any dangerous driving causing bodily harm offence where DUI is an element,

  • Two offences within 5 years having a BAC between 0.05% and 0.149%,

  • Failure to comply with giving a breath sample to WA Police.

Road Safety Commissioner Kim Papalia said drivers had been given plenty of warning ahead of the introduction of the new legislation.

“West Australians have been exposed to a confronting television and radio advertising campaign over the past five weeks,” said Mr Papalia.

“The West Australian Alcohol Interlock Scheme is not retrospective, so all drivers will start with a clean slate from Monday October 24th. This is a chance for those drivers convicted of drink driving offences in the past to change their behaviour, and not get behind the wheel of a vehicle if they have been drinking.”

According to WA Police, to September 30th this year, 45 people were killed on WA roads where alcohol was suspected in a driver or motorcycle rider involved in the crash, six more fatalities than the 39 recorded over the whole of 2015.

Convicted drink drivers who wish to drive after the initial disqualification period will have an ‘I’ condition placed on their licence for at least six months, and must pay to have the alcohol interlock device installed by an approved service provider.

Vehicles will also have to be presented to a service provider every month for the performance data to be monitored, at the cost of the interlock driver. The cost of an alcohol interlock is estimated to be $1600 over a six-month period. Offenders who do not have an interlock fitted will not be allowed to drive.

It is expected between 4000 and 6000 high end and repeat drink drivers will be required to enter the WA Alcohol Interlock Scheme every year.
