2. The Foundation: Liability Coverage

Liability insurance acts as the legally required bedrock for almost every auto policy in the United States. This coverage is broken down into two parts: bodily injury liability, which assumes the medical costs of another individual if you are at fault in a crash, and property damage liability, which pays for the destruction of someone else's vehicle or belongings.

Each state establishes its own bare-minimum limits, usually displayed as a sequence of three numbers (such as 25/50/10, meaning $25,000 per individual for injury, $50,000 total per crash for injury, and $10,000 for property destruction).
