JUST when we had hoped the message might finally be getting through comes a stark reminder that there is always more to be done.
Recent drink-driving blitzes on our roads, particularly during holiday periods, have generally ended in police praising the good behaviour of [most] drivers.
Those double demerit periods usually result in a few speeding offences and only the occasional-drink driving charge.
That's still more than we'd like to see, but recent numbers have been few enough to suggest the combination of double demerits and very high visibility policing is having a positive impact.
And then we have a day like Australia Day on Sunday.
Despite all the publicity that accompanied the long weekend drink-driving blitz, officers attached to Chifley Local Area Command still caught three drivers over the limit and another they will allege was drug-affected while behind the wheel.
Police were naturally disappointed with the driver behaviour and the drivers themselves are no doubt upset they have been charged, but it could have been much worse for them.
The clear lesson is that when it comes to drink-driving education, too much can never be enough.
That means that almost 40 years after the introduction of random breath testing in this state, we need to still keep finding new ways to get across the message that drinking and driving and do not mix.
And we need to keep finding new ways to get across the message that getting it right most of the time just isn't good enough. Drivers, need to get it right every time.
Getting behind the wheel just once when you're over the limit is not good enough.
Allowing yourself to become distracted just once while behind the wheel is just not good enough.
Letting your self speed just once because you're running a little late is just not good enough.
Just when we think we might be winning the war is the time to start thinking of another approach because, sadly, there will always be people ready to make bad decisions.
We should not need more police on the road and we should not need more RBT blitzes.
But nor should we need to remind people to slow down, put on their seatbelt and not pick up their mobile phone while driving.
Apparently, though, we do.
