Well, at least you made a police report. Sad case is that if you langgar someone at the back be the vehicle in front illegal or not, you still have to take action for it. Which sucks at times for people who exploit and manipulate that ruling. I remembered that I was involved in a 5 car accident at a traffic light around 8 years ago. I was the 2nd car. Luckily there was a gap in front of the first car. The last car banged the fourth car really bad, belakang total. Hit the 3rd car, dented the front and rear and hit the 2nd car. 2nd car driver hit my rear, slightly made my bumper senget but cannot close my bonnet. Worst, it was in the morning...sheesh. Of course the car in front of me terus cabut like nothing happened hahaha. Best part, lorry bumped a lorry in front of police at the crime scene. Reason watching the crime scene haha.
Cars involved: Modified Putra (5th Car), Gen 2 (4th car), Myvi SE (3rd car and just came out of showroom as told by the owner), Puegot 405 (2nd car) and Corolla (1st car).
As insurance goes, I claim from 2nd car, 2nd car claim from 3rd car, 3rd car claim from 4th car, 4th car claim from 5th car. Felt sorry for the 4th car, P driver and his gen2 rear totally wrecked. saw the face like totally traumatized. GF / sister also traumatized. Also, pity the 3rd car as the guy and wife just got the car weeks before the accident. Keta baru dah kena langgar.
If they think they can go to private / specialist hospital and get claim a lot of money from you, I wouldn't be surprised if the doctor referred them to General hospital which brings back to square 1 hahaha.
