Table Four Numbers of accidents for which each contributory factor was recorded - 2006
NB: as described in the text, "repeats" of CFs are excluded for the purpose of producing this table.
In cases where two or more participants in an accident have the same CF, that CF will be counted only once in this table.
For example, an accident with two participants who were "exceeding speed limit" and one who was "following too close"
would be counted once against "exceeding speed limit" and once against "following too close".
