Police in Victoria have been banned from shooting at moving vehicles in all but the rarest circumstances following a series of rammings and officers firing at vehicles.

In separate incidents this month, a driver was fatally shot by a sergeant pinned against a wall by a van in Tullamarine, an officer fired his gun at a stolen car in Berwick and another fired at a car involved in a police car ramming in Wodonga.

"Shooting at a moving vehicle is potentially extremely dangerous for members, the offender and the community," a police spokesman told AAP on Monday.

"It will only be in the most critical and rare circumstances that the use of a firearm may be considered appropriate."

Some offenders have recently been more willing to drive at police, Victoria Police says.

Police figures show 14 police members were injured during 103 police vehicle rammings in 2015/16.

In the previous year, just four members were injured and 36 vehicles were rammed.
