If your vehicle registration isn't up for renewal soon, you might be able to put the vehicle into "storage protection." What this means is the vehicle is not legally allowed on the road, but will still maintain comprehensive coverage
in order to protect the vehicle from theft and weather damage. This will also help reduce your premium without having to cancel your insurance or registration. Be aware, because the vehicle does not have the state required liability coverage,
you or anyone else isn't allowed to drive the vehicle. Moreover, it's probably best to keep the vehicle securely place in a garage or off the streets. Your best bet for this coverage is to speak with your current provider as most providers have something like this. Best of luck.
