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

a<p>This group may also contain passengers but probably notmany as “unspecified occupant” was rare for collisions.These have been included in the fatality rate estimate.</p>b<p>Estimates 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.</p>c<p>Note 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.</p>d<p>This figure is greatly exaggerated by under-measurement of under-aged driving.</p>e<p>The base for this was much smaller than distances for other ages, sex, and travel modes.</p>f<p>These figures are too high as V19.8 is a dustbin code, including some off-highway falls.</p>g<p>Not included in the fatality rate.</p>h<p>Estimates are too low, as some ‘unspecified location’ deaths will have been on-highway.
