Questions regarding Rules

[Killjoy]

Are police authorised to use such force to bring a vehicle to a stop or to simply slow it down if the circumstances warrant it.

When police officers open fire, they always have to assume this will severely injure or kill their suspect. This should establish a frame of when it's okay to shoot, mainly when the target must be stopped at all costs.

Ive been told if a driver is a direct threat to you and or those around himself/ has just run someoneover and is not stopping and is going to end up killing someone else, lethal force can be used.

If the person inside does indeed present a great threat to lives, then yes. you can fire - assuming you would do the same if he were running on foot.

Though with the new damage system a new non lethal alternative has emerged to bring the vehicle to a stop.

Irrelevant. When police officers fire upon vehicles, they always have to acknowledge themselves that bullets can hit the driver, any passengers, any cargo or bystanders. Always assume the worst.
