A weekend blitz by police nabbed three drink drivers in the space of eight hours. Even more disturbingly, one of those caught was already a disqualified driver.

Three offenders may not seem like a lot, given the number of motorists that would have been on the roads in that period of time, but let us remember that drivers under the influence of alcohol are potential killers.

Even one on the road constitutes a hazard to other motorists.

The police conducted this recent blitz as part of Operation Eureka, which began in December last year and has so far caught 16 drink drivers in Ballarat.

The operation focuses on the "random" in random breath testing by setting up short-term stations in streets around Ballarat on non-specific days.

That way, according to police, drivers will be unable to predict where they might encounter a breath-testing station.

As a program, Operation Eureka will run until June.

Beyond that, though, motorists shouldn't be complacent.

Drink-driving remains a concern within our community and there will be an expectation that police will continue to target it beyond formalised programs.

While this undoubtedly requires a further stretch of already strained resources, eliminating menacing motorists from our roads is not something we can afford to drop the ball on.
