Every state except New Hampshire requires at least liability insurance. Minimum liability limits vary by state but are generally expressed as three numbers, for example 25/50/25, meaning $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $25,000 for property damage. These minimums are typically too low to fully protect you in a serious accident. Most advisors recommend at least 100/300/100.
