Alarming increase in drugged driving deaths
More road deaths in 2017 involved drivers with drugs in their system than over the alcohol limit, figures
obtained by the AA reveal.
The table below shows the number of crash deaths where a driver subsequently tested positive for some form of
potentially impairing drug and compares those numbers to crash deaths involving a drunk driver. Some drivers will have
tested positive for both drugs and alcohol.

“These figures confirm how big a problem drugged driving is on our roads and why we have to give Police saliva-based
testing devices to catch impaired drivers,” says AA road safety spokesperson Dylan Thomsen.
“We now have more crash deaths where people test positive for a drug than alcohol – it’s time to act.”
The AA is reiterating its Election Call from last year for the Government to give Police more tools to test and catch
dangerous drugged drivers on our roads.
Excluding alcohol, the two most commonly detected individual drugs were cannabis and P. A particularly worrying trend is
that the cases of P being detected has shot up in recent years. A range of other drugs and medications that impair
driving also feature in the results.
While the numbers look like drugged driving has suddenly skyrocketed, the AA believes the big jump is likely down to
more thorough testing being done following crashes.
“The number of drivers found to have drugs in their system is no surprise to the AA,” says Dylan.
“The AA has called drugged driving a silent killer on our roads for years and these latest figures confirm how prevalent
drugs are in fatal crashes.
“No one wants someone who is high driving towards their family at 100kmh but right now the chances of being caught
drugged driving is tiny. We have to change that.
“95% of AA Members in our surveys support introducing saliva-based drug testing.”
The current system for Police to test a driver for drugs requires an officer to have strong cause to suspect drug use
and then take close to an hour to take the driver to a Police station for an old-fashioned walk-and-turn test.
”Right now we don’t believe the Police have the tools they need to get drugged drivers off the road and deter people
from doing it,” says Dylan.
“The current system almost needs a driver to be sitting in the car with drugs on the seat next to them to get tested and
the current test takes up a huge amount of an officer’s time – meaning the chances of drugged drivers being caught are
“The saliva testing devices being used in many other countries would be much faster and allow many more potentially drug
impaired drivers to be tested than the current approach.”
Although the saliva tests would initially only detect common illicit drugs (like cannabis, P and ecstasy), the AA
believes it is better to test for some impairing substances rather than none.
“Random roadside drug testing would send a strong message that you’re endangering yourself and others if you drive
impaired, and this doesn’t just apply to alcohol,” says Dylan.
A question the AA commonly hears is whether testing devices could detect drug use from well before when someone was
driving? Because the testing devices use saliva they are designed to catch people who have used drugs within a few hours
of getting behind the wheel.
An initial positive test can also be followed by a second test to confirm the result is accurate.
“The AA knows there are opponents of roadside drug testing who have concerns about the accuracy and speed of the devices
but these can be answered by using them in a targeted way and having confirmation tests to double-check results.
“Drug testing does cost more than alcohol testing but the Ministry of Transport has estimated that every dollar spent
would deliver $8 in savings from having fewer crashes on our roads.
“Drug testing of drivers is working in Australia, the UK, France, the Netherlands, Norway, Denmark and Ireland and it
can work here.”
* The figures come from testing that is done by authorities following a fatal crash and where there was evidence that a
driver was affected by a drug likely to have impaired their driving ability. Illegal drugs, prescription medication
known to impair driving or levels of substances above medical recommendations are all included in the drugs proven
