DRIVERS have been warned to slow down after 187 people were caught speeding by Oxley Highway Patrol at the June long weekend.
Operation Stay Alert wrapped up on Monday and saw more than 2900 drivers randomly breath-tested in the north west region and several fatal crashes across the state.
A number of vehicles left the road and hit other objects, Highway Patrol assistant commissioner Michael Corboy said.
"While the causes of all the crashes on the weekend are still under investigation, I would encourage all drivers or riders to be aware of their surroundings and take breaks if they are tired," he said.
"It doesn't matter where you are travelling to, crashes do not discriminate, they can happen anywhere and at any time."
Officers pulled over four people not wearing seat belts in the Oxley Police District during the operation.
