We were in traffic everything was fine suddenly at high speed this truck comes from behind and hit us not one or two times 5 times continuously like stop and then hit again I slammed my brake so hard cause he was dragging me forward towards the car standing in front. Accident occur exactly front of police station. The police stop the truck and divert the traffic truck was pull aside and found the driver is drunk I was with my family my dad and police officers took the key of the driver and made him call his owner after 1hr heated argument he paid us 6000rs for repair and then we let him go the police really cooperated with us. The truck slammed us so hard that the inside boot plastic cover got bend little bit. Idk how much it's gonna cost to repair the boot also my car have third party insurance. I need help ragarding repair from this community like what can be the cost of it. Tomorrow I am going to service centre to get quotation for it.
