1. Includes only accidents where a police officer attended the scene and in which a contributory factor was reported.

NOTE: the basis upon which the combinations are produced is described in the text.

However, an additional example may be helpful.

Suppose that the "defective brakes" CF has been allocated to participant A, the "failed to look properly" CF has been allocated to two participants A and B, and the "failed to judge other person's path/speed" CF has been allocated to participants A, B and C,

The following combinations of CFs would be allocated to the same participant:

A defective brakes + A failed to look …

A defective brakes + A failed to judge …

A failed to look ... + A failed to judge …

B failed to look ... + B failed to judge …
