Police in Victoria have been given the power to shoot to kill drivers who deliberately risk the lives of the public in a new hostile vehicle policy.
The move - a first in Australia - is designed to help protect the public from rogue drivers who use their vehicles as a weapon.

The policy includes a raft of new measures police can take, including ramming the rogue driver, creating car blockades and, as a last resort, shooting the driver.
The move comes before a coroner's inquest into the death of six people who were run down in Melbourne's Bourke Street Mall.
The inquest will examine if police could have stopped the fatal attack, carried out by James Gargasoulas in January 2017.
Deputy Commissioner Shane Patton told The Age the policy was the result of 18 months of research.
"It provides clarity for members on the street," he said.
"It is saying that they will be supported if they need to take action and states clearly that they must take action."
"We will not wait for offenders to plough into people. The instructions are that you must do something, that you must stop these attacks and that the response must be proportionate and justified," he told The Age.
