What do auto liability limits like 100/300/100 mean?

Those three numbers describe your liability coverage in thousands of dollars. With 100/300/100, the policy pays up to $100,000 for bodily injury per person, up to $300,000 for total bodily injury per accident, and up to $100,000 for property damage per accident. State minimums are often far lower, like 25/50/25, which can be wiped out by a single serious injury — and once the policy maxes out, the injured party can come after your personal assets and future wages. For anyone with savings, a home, or a decent income, 100/300/100 is a sensible floor, and going higher is cheap relative to the protection. Carrying low limits to save a few dollars a month is one of the riskier insurance decisions people make. If you have meaningful assets, also consider an umbrella policy on top.
