How long do I have to add my new vehicle to my existing policy?

I just traded in my old car and drove off the lot in a new one. The salesperson asked if my trade-in was insured but didn't say anything about needing to add the new car to my policy. How long do I actually have to get it added, and am I covered in the meantime?

Most car insurance policies include what's called automatic or replacement vehicle coverage. When you buy a new car, your existing policy typically extends coverage to it for a short grace period, usually between 7 and 30 days depending on your insurer. During that window, your new vehicle generally carries the same coverage as the car you replaced.

There are a few important things to know, though. If the car you traded in only had liability coverage, that's all that would automatically extend to the new vehicle. So if you're financing and your lender requires full coverage, you'll want to add it immediately rather than relying on the grace period. Most lenders require full coverage as a condition of the loan, and a gap could put you in breach of your financing agreement. This is also the case if you previously had liability and just want more coverage, required or not.

It's also worth knowing that the grace period isn't guaranteed by law in any state. It's offered at your insurer's discretion and the length varies. Some carriers give you 30 days while others may only give you 7.

The safest approach is to call your insurer the same day you purchase the vehicle, let them know you have a new car, and confirm what's covered and for how long. It's a quick call that can save you a significant headache if something happens before you officially add it to the policy. Some carrier apps even let you do it through their system pretty easily, too.

Congrats on the new car, hope this helps!
