You must keep the primary address of your car updated and accurate to protect cover. When we state 'overnight location' or 'garaging', we mean the primary address/location where your car will be kept. You are welcome to take trips or spend time away from your home location and still maintain your cover.
If you were to move, or if the vehicle no longer primarily stays at the address listed on your Progressive policy (possibly due to schooling, staying prolonged with friends/family, etc.), then it is your responsibility to update your policy to reflect the correct location where the car would be kept. Failure to do so could compromise your cover in the event of a claim.
