a

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.

b

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.

c

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.

d

This figure is greatly exaggerated by under-measurement of under-aged driving.

e

These figures are too high as V19.8 is a dustbin code, including some off-highway falls.

f

Not included in the fatality rate.

g

Estimates are too low, as some ‘unspecified location’ deaths will have been on-highway.
