Cheapest car insurance can vary depending on where you live and what type of coverage you are looking for. Generally speaking, liability insurance is the cheapest car insurance available because it does not cover any damage done to your own vehicle. Liability insurance usually covers other drivers and their property, such as their vehicle and any items that are in it. You may also see it referred to as "basic" insurance or minimum requirements insurance.
On the other hand, full coverage car insurance is the most comprehensive kind of insurance and can be quite expensive. It typically offers coverage for you and your vehicle, including comprehensive and collision coverage. This type of policy covers damage to your own car should you be at fault in an accident, and usually also covers uninsured/underinsured motorist coverage in case of an accident with an uninsured or underinsured driver.
Overall, it is difficult to say what the cheapest car insurance is because it depends on many factors. It’s important to shop around and compare offers from multiple insurers to find the best policy that fits your budget and needs.
