To make changes to your car insurance policy, you can contact your insurance company directly via phone or email. You can also log into your account on their website if they have one.
Once you are in contact with your insurance company, you can let them know what changes you would like to make to your policy, such as adding or removing a driver, changing the level of coverage, or updating your personal information.
They will then guide you through the process of making the changes to your policy. It is also possible to compare options from different companies to find the best policy for you.
