Danger for drivers
Alcohol is a mood changing legal drug that slows down your central nervous system and impacts your driving ability. In 2019, 61 people were killed, and 285 seriously injured, in alcohol related crashes on NSW roads.
Blood alcohol limits
NSW has three blood alcohol limits for drivers: zero, under 0.02 and under 0.05. The limit that applies to you depends on your licence and the type of vehicle you are driving.
Getting back to zero explains how long it can take to get alcohol out of your system. If you have had a lot to drink, you may be over the limit for much of the next day and should not drive.
Random breath testing
Since the introduction of random breath testing in 1982, deaths from alcohol related crashes on NSW roads have been greatly reduced. In 1980, 389 people were killed in alcohol related crashes in NSW, 30 per cent of the road toll. In the three years 2017-2019, 17 per cent of fatalities involved alcohol.
Drugs and driving
It is dangerous for drivers and riders to take stimulants and other illegal drugs. Cannabis, cocaine and similar drugs affect your driving skills and concentration, even though you may think you are driving well.
Prescription drugs and over the counter medicines can also reduce your ability to drive safely. They can affect your eyesight, concentration, mood, coordination and cause slower reaction times. Mixing one drug with another, or mixing alcohol with other drugs, increases your risk of having a crash.
Combined drink and drug driving offence
Since 28 June 2021 a new law introduced harsher penalties for combined drink and drug driving offences.
Tougher penalties apply for a combined offence, compared to those currently available for separate drink and illicit drug driving offences.
This offence will increase deterrence and send a clear message that mixing alcohol and illicit drugs and then getting behind the wheel will not be tolerated on NSW roads.
Mobile Drug Testing (MDT) at the roadside in NSW operates alongside Random Breath Testing (RBT) for alcohol and targets four illicit drugs - cannabis, cocaine, speed/ice and ecstasy. MDT is increasing in NSW, with police undertaking up to 200,000 roadside drug tests each year.
Driving under the influence of an illegal, prescription or over the counter drug
MDT is not the only method to detect drug driving. The second type of drug testing applies where a driver shows signs of being impaired by a drug at the roadside. Police can arrest you if they suspect you are driving while impaired by illegal drugs or medicines and you fail a sobriety assessment.
You will be taken to a hospital to give samples of blood and urine for drug testing. This testing can detect a wide range of illegal drugs, as well as medicines.
In a crash where someone is killed, blood samples are taken from all drivers involved and may be tested for drugs.
If you take prescription or over-the-counter medicines, it is important to always follow medical advice and the manufacturer’s instructions and only take the drug as prescribed.
If you have concerns about how a drug may affect your ability to drive safely, it is best to discuss this with your doctor or pharmacist.
