Insurance claim for the damage suffered by the motor car

Mr. A has to get FIR registered and claim submitted against the owner, driver and insurance of the offending lorry hit the car from behind 

Besides what Dr. J. C. Vashista says, on the spot evidence at the site of the accident will have to be taken by the police. In India only in the case of serious accidents involving heavy damage, injury or death, the police acts to determine who is responsible for the accident, takes panchana etc. If the case is contested it will go to the tribunal. Witnesses also will be required. In India it is dfficult to get witnesses.

Mr. A has two possible options for making an insurance claim:

Third-Party Claim: If the lorry driver was at fault, Mr. A can file a claim against the insurance company of the lorry. This falls under third-party insurance, where the insurer of the lorry compensates for damages caused to Mr. A’s vehicle2.

Own Damage Claim: If Mr. A has a comprehensive insurance policy, he can claim damages from his own insurance company. In this case, his insurer will cover the repair costs, and if applicable, later recover the amount from the lorry’s insurer2.

 To proceed, Mr. A should: Report the accident to the police and obtain an FIR. Inform the insurance company immediately. Gather evidence, including photos of the accident and witness statements.

Follow the claim process as per his policy terms2. Would you like guidance on filing the claim step-by-step?
