"Because the principal harm done by these offences (the death of a person) is an element of the offence, the fact that primarily determines the starting point for sentence is the culpability of the offender. Accordingly, for all offences other than causing death by driving: unlicensed, disqualified or uninsured drivers, the central feature should be an evaluation of the quality of the driving involved and the degree of danger that it foreseeably created. These guidelines draw a distinction between those factors of an offence that are intrinsic to the quality of driving (referred to as determinants of seriousness) and those which, while they aggregate the offence, are not."
"Where more than one person is killed, that will aggravate the seriousness of the offence because of the increase in harm. Where the number of people killed is high and that was reasonably foreseeable, the number of deaths is likely to provide sufficient justification for moving an offence into the next highest sentencing band."
