Operation Gilly5 was officially launched last Thursday as part of this co-operative effort.

Signs will be erected soon telling motorists not to speed and also advising them of more random breath-test units.

High-tech lasers will be used to catch speeding motorists.

Under Operation Gilly 5, Blacktown police will work longer shifts monitoring not only main roads but also side streets and short cuts that motorists often use.

The Highway Patrol supervisor for Blacktown Local Area Command, Sergeant Stacey Ziogos, said people who were caught drink-driving would be arrested and taken to court.

``You will be fined, lose your license and have a criminal record,'' she said. ``It's just not worth the risk to your licence. We test more than 2000 drivers for alcohol in a typical operation.''

The Blacktown Liquor Accord, which is a voluntary group of licensees, the public and businesses, is also involved in the safety campaign.

Accord chairman Neale Vaughan said people would be doing themselves and the community a favour by choosing not to drink and drive.
