How do I get adequate liability cover for driving in USA?

If I am hiring a car in USA, how can I ensure I have adequate liability cover?

We do not provide personal liability cover for the use of mechanical vehicles, you will need to get personal liability with your car hire.

Check with the car hire company exactly how much third party liability cover is provided. Some car rental companies only provide the legislated state minimum; this varies between states and can be as low as $10,000. We suggest you have at least $1,000,000 third party liability cover - you can purchase further cover if it is not included as standard from your car rental company.
