Insurance terms, definitions and explanations are intended for informational purposes only and do not in any way replace or modify the definitions and information contained in individual insurance contracts, policies or declaration pages, which control coverage determinations.

The cheapest car insurance, period, will likely carry the minimum coverage required in your state.

The Third Party Liability is also called as Liability Only or Act Only, and is mandatory by law for all vehicles plying the roads in India. The Liability Only covers the legal liability of the third party against damages to the property or any injury/death caused by your car. The policy type does not cover you or your vehicle.

While the above is the lowest amount of insurance coverage you can have, you should consider adding more if you have more to lose. For example, we typically advise drivers to match their liability coverage to what they have in total assets. If you own a house in one of the most expensive zip codes in California, Atherton, and have sizable savings and investment accounts, we'd recommend you increase your liability limits and consider adding umbrella coverage on top.
