Contact your insurance agent and ask if they can put your vehicle on a storage plan.
When a car is put in storage, it no longer meets the legal requirements to be on the road. Therefore, during this time, no one can drive the car and you should check with your local DMV to see if your plates would need to be surrendered.
If your car insurance company says no to the storage idea, you have two options:
If you continue to pay, just lower your coverage to the state minimum to save money. If you cancel your coverage, you technically are in a lapsed period, which may affect your rates when you return the the U.S. and ultimately cost you more money. However, if you don’t want any expenses while you’re abroad, you may want to cancel your insurance.
