The quick answer to that question is;" State minimum Auto Liability coverage.."
The best answer is:
1. All states require that any car being driven on public roads must carry as least minimum liability insurance. When you own a car you must carry liability insurance to pay for losses you may cause to someone's body or property with your vehicle.
2. The statement, 25/50/10, is an example of Split Limit liability. The first two numbers are for Bodily Injury. The third number is for Property Damage.
3. The first 25 is $25,000 is the maximum payable per person who is injured. The 50 is $50,000 is the maximum that would be paid per accident. If there are more three or more people injured the money will have to be apportioned out.
4. . The bodily injury liability is to cover doctor's/hospital bills, lost income, pain and suffering and, possible, disability settlements. However, the insurance company will only pay the actual loss. The full amount of liability is not a guarantee to pay that amount.
5. The property damage liability is to pay for damage to another person's property caused by the collision. That may be their car, their garage door, a road sign or the side of their house or any property damaged by your vehicle.
6. Higher Limits of liability are always recommended. Amounts such as 50/100/50, 100/300/100, 250/500/250 or 500/1000/500 are available. They can be in variables of those numbers, also.
