When you make an injury claim against a friend or relative who was the at-fault driver in a car crash, their insurance premiums are likely to increase. However, their premiums will likely increase regardless of whether you file an injury claim simply because they were at-fault in the accident and will probably have to file a claim for property damage to the vehicle even if your friend or relative was not injured at all. This means that while it’s understandable that you’re concerned about your friend or relative’s insurance premiums, it should not be a factor that influences your decision about filing a claim.
