1 Includes only collisions where a police officer attended the scene and in which a contributory factor was reported
2 collisions with more than one CF in a category are only counted once in the category total.
3 Columns won't sum to 100 per cent as collisions can have more than one CF
4 Includes all contributory factors eg if two cars are involved in the same collision and both are exceeding the speed limit this would count as 2 CFs.
