DRIVERS had nowhere to hide as police blocked both north-bound lanes of the Bruce Hwy last night in a massive police blitz.

About a hundred cars stretched single file for more than a kilometre along the road leading into the Ettamogah Pub as police checked vehicles heading north.

Motorists were tested for drugs and alcohol, and police conducted vehicle and licence checks in the pub's car park.

Coast-based police dogs trained to sniff out cannabis were also being used.

Though drivers had to wait for quite a time, there had been no incidents.

In a statement this morning, police said officers from throughout the district, including plain clothes and uniformed police, as well as officers from the State Traffic Taskforce and the Random Drug Testing Unit conducted nearly 1000 random breath tests and 48 random drug tests.

Four drivers tested positive to amphetamines.

Seventy-three traffic infringement notices were issued, as well as nine Notices to Appear on a total of 10 charges, four of which were drug related and five traffic related offences.

The operation was the beginning of a two-week school holiday crackdown on drivers entering the Coast.

Caloundra Senior Sergeant Troy Pukallus said the operation sent a strong message to drivers.

"We want drivers to be aware that we are serious about road safety and we will be making our presence known," he said.

"This operation, as well as others, is our way of letting drivers know that police are going to be out anytime, anywhere."

The highway was blocked from the slip lane to the Ettamogah Pub and Aussie World, with all incoming traffic diverted through for testing.

More than 40 police officers - from the Sunshine Coast, the State Traffic Taskforce and Brisbane Drugs Taskforce - stopped drivers in the three-hour blitz between 9pm and midnight.

They expected to process more than 600 vehicles in the operation.

Snr Sgt Pukallus said past operations had resulted in a number of people being apprehended for driving without licences and the detection of an alarming number of drink-drivers.

"It is quite shocking the amount of motorists who drive under the influence of either drugs or alcohol, and do not expect to be pulled up," he said.
