I was reading the CPS guides on death by careless driving and it has a section on causation.
causation is defined as "but for the defendants actions the forbidden harm would not have happened"
like all other elements of the offence this has to be cause beyond all reasonable doubt
in a case where someone is speeding in a 30 limit and causes a death
assuming 30 is held to be a speed a carefull and competant driver would do on that road
there is 15.5% risk of death when crashing into a pedestrian at 30mphhttps://www.aaafoundation.org/sites/def ... sSpeed.pdf
This means that if a person is doing any speed ubove that there is a only an 85% chance max that the death would have occured but for their careless driving.
proof beyond all reasonable doubt has not been achived.
Is this often a problem in these cases?
