Your policy will renew automatically if you don’t respond to their correspondence about renewal. If you accept the new rates and don’t need to make changes to your policy, then your work is done.
If your policy for some reason doesn’t renew automatically, or you need to alter your policy or coverages, then you’ll need to contact your insurance representative. Make sure your coverage doesn’t lapse! In most states, it’s illegal to drive without insurance, even if you didn’t know your policy expired. It may also lead to a higher premium later.
Good luck with your renewal!
