I have just returened from the scene of an accident i was involved in with 2 other cars and need some help.

Weather was really bad, one car has braked the car behind has braked sharply and then the card behind that has also braked sharply.

The front car has minor damage, the middle car is a write off and has front and back damage, the back car has front end damage and is also a write off.

IN THE EYES OF THE INSURANCE WHO IS AT FAULT CAR 1, CAR 2 OR CAR 3
