Fatality numbers and rates per distance travelled, by travel mode, age, and type of incident, Females, England 2007–2009.

aThis group may also contain passengers but probably notmany as “unspecified occupant” was rare for collisions.These have been included in the fatality rate estimate.bEstimates are likely to be a little too high due to the assumption that unspecified occupants are all drivers: an unknown proportion would have been passengers, especially for females.cNote that these averages include both local roads and motorways/multi-lane divided roadways, where fatality rates are an order of magnitude lower than general purpose roads, but data are not available by age and sex.dThis figure is greatly exaggerated by under-measurement of under-aged driving.eThe base for this was much smaller than distances for other ages, sex, and travel modes.fThese figures are too high as V19.8 is a dustbin code, including some off-highway falls.gNot included in the fatality rate.hEstimates are too low, as some ‘unspecified location’ deaths will have been on-highway.
