Handing Somebody the Keys

The short version most people have heard is that insurance follows the car. It is a decent rule of thumb and it has enough exceptions to be worth ten minutes of your attention before the next time a friend borrows your truck.

The general principle

Your auto policy is written on your vehicle, and it commonly extends to a person driving it with your permission. If your neighbor borrows your car for an afternoon and has a collision, your policy is normally the one that responds first, and your deductible is the one that applies. Their own policy, if they have one, may come into it afterward for amounts beyond your limits.

That has a consequence people do not expect: the claim goes on your record, not theirs, because it was your policy that paid.

Where the general principle stops

• Excluded drivers. If someone is named as excluded on your policy, they are excluded. Letting them drive the car is one of the few genuinely catastrophic mistakes available in personal insurance.
• Household members who were never disclosed. Everyone licensed in the household is expected to be listed or formally excluded. An undisclosed regular driver is a problem waiting for a claim.
• Regular use rather than occasional borrowing. The extension contemplates permissive use, not somebody who effectively drives your car every day. If that is the situation, they belong on the policy.
• Driving for money. Delivery, rideshare, or anything for hire is generally excluded regardless of who is at the wheel.
• Unlicensed or suspended drivers. Handing keys to someone you know should not be driving creates exposure for you personally, beyond the insurance question.

The practical script

Before you lend the car, ask yourself three things: is this person licensed and sober, are they excluded on my policy, and would I be comfortable with this claim being on my record. If all three answers are fine, lend the car.

The reverse case

When you borrow someone else's car, their coverage is generally primary and yours may sit behind it. If you frequently drive cars you do not own and have no policy of your own, that is a real gap and there are ways to address it — ask rather than assume you are covered by someone else's kindness.

If your household has changed, tell us who is driving what. It takes a minute and it removes the worst surprises.
