Lending a car to a friend or family member feels like a small favor right up until it isn't. A tree, a fence, a parked car — suddenly what was a simple yes has real damage attached to it, and nobody's sure whose responsibility it actually is.

In most states, insurance follows the car, not the driver. That means your own policy is typically the one that responds first, regardless of who was actually behind the wheel, as long as the person had permission to drive it. This surprises a lot of car owners, who assume the driver's own insurance would cover it instead.

This is exactly why permissive use matters, and why it's worth being clear about who you're actually comfortable lending the car to. A policy generally covers occasional, permitted use by someone you've allowed to drive, but coverage can get murkier if the person drives your car regularly without being listed on the policy at all.

After the fact, your own insurance company handles the claim, and depending on the accident's cause and cost, your rates may reflect it going forward, the same as if you'd been driving yourself. The driver's own insurance may become involved secondarily, but the first call almost always goes to whoever's name is on the car's policy.

Before handing over keys casually, it's worth knowing that "it's just for an afternoon" can still end up being your policy's problem to sort out, not theirs.
