补充第三者责任险（LIS）为您提供高达1百万美元的附加保护，用于承保交通事故当中伤者对您提起的人身伤害和财产损失赔偿。

如果有人对您提出索赔，LIS就会对首次的1百万美元进行赔付，以保证您的保单生效以及/或者保障您的个人财产。

在大多数州，一旦您购买了LIS，则事故造成的第三者人身伤害和/或财产损失总额当中未上保险或保额不足的部分，可以通过额外支付一笔费用获得每次事故高达1百万美元的赔付。

在康涅狄格州和纽约州，LIS包括保额高达1百万美元的摩托车事故造成的第三者人身伤害和/或财产损失总额当中未上保险或保额不足的部分。 

Liability Insurance Supplement (LIS) provides you with up to $1 million of increased protection should bodily injury and property damage claims be made against you by people injured in an accident.

LIS safeguards your insurance policy and/or your personal assets for the first $1 million should such claims be made against you.

In most states, uninsured/underinsured coverage up to $1,000,000 per occurrence for combined bodily injury and/or property damage claims is available for an additional charge - but only if you purchase LIS.

In CO and NY, LIS includes uninsured/underinsured motorist coverage up to $1,000,000 per occurrence for combined bodily injury and /or property damage claims.
