In some cases, the driver who caused you to swerve pulls over afterward. Or, maybe they still made contact with your car — they hit you — even though you were trying to swerve to avoid them. Either way, if they are around after the scene or involved in the accident, that’s actually in your favor. It means one more person there who can confirm what happened, and in many cases, it may mean that they are at fault and can be held liable. You should talk to a car accident lawyer and pursue it like any other accident claim.
