These checkpoints would operate 24/7 short term before police move to a new model which will involve random checkpoints and spot checks across the district to check that people were complying with the travel restrictions, Hill said.

He said the checkpoints would not be stopping every car and would not hold up traffic "unnecessarily" but travellers should be prepared to be stopped.
