Danger for drivers
Alcohol is a mood changing legal drug that slows down your central nervous system.
Alcohol and driving shows how it affects your skills, mood and behaviour. Just a few drinks increases your blood alcohol concentration and as that rises, so does your risk of being in a crash:
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.
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. Mixing one drug with another, or mixing alcohol with other drugs, increases your risk of having a crash.
