If you have Progressive insurance and need to provide proof of garaging, there are a few options available. The first is to log in to your account on the Progressive website and print out a copy of your policy declarations page. This will show your current address and the location where your vehicle is being kept. If you need to provide proof of garaging for a specific period of time, you can also request a letter from Progressive that states the dates that your vehicle was kept at your current address.
