MOTORISTS making their way along Dayboro Rd in the past couple of days may have received some unusual driving advice.

On Sunday, a flashing roadside variable message sign (VMS), located next to Lake Kurwongbah, North of Brisbane, was advising passers-by to “Speed Up Dont be Pu**y.”

Then, about 2.30am on Monday, Whiteside resident Robert Cooke was driving his taxi home when he saw the same sign, this time with a different, but equally alarming, message.

“It said ‘Driving Tired Try Cocaine’,” Mr Cooke said.

“I was sort of in autopilot mode and had to do a U-turn to go back and check it.”

Mr Cooke said he did not heed the sign’s advice.

“I couldn’t find a coke dealer at that time in the morning,” he joked.

The roadside VMS was put in place by Seqwater and was supposed to be displaying information about dam levels in Lake Kurwongbah.

A Seqwater spokeswoman said the sign was supposed to read: “Plan ahead. Sign up 4 dam alerts. Seqwater.com.au”

“The sign was switched off as soon as it was brought to our attention that the message had been tampered with,” she said.

“The sign was hired through an external provider who has now disabled remote access to ensure it cannot be altered on-site.”

She said investigations into how the sign was hacked were continuing.
