How to speed up an insurance claim after a car accident

My sibling was in a car accident yesterday and damaged two other cars. He is just about to file his insurance claim.

For those who have filed a claim before to cover accident-related damages, what steps did you take to make the process faster? How did you get your claims approved, especially for third-party property damage?

Would really appreciate any advice. Thanks!
