What Is Liability Insurance Insurance?
Liability insurance is split into two components: bodily injury liability, which pays medical bills, lost wages, and legal costs when you injure someone in an accident, and property damage liability, which covers repair or replacement costs when you damage another person's vehicle or property. Your carrier pays claims up to your policy limits, then you're personally responsible for any amount beyond those limits. Maryland law requires you to carry liability coverage to register a vehicle and drive legally, but the state-mandated minimums leave significant gaps if you cause a crash with serious injuries or total a newer vehicle.
- You rear-end a stopped car at a traffic light. The other driver suffers a concussion and misses three weeks of work, generating $18,000 in medical bills and $6,000 in lost income. Their vehicle sustains $9,000 in damage. Your bodily injury liability covers the $24,000 in medical and wage claims up to your per-person limit, and your property damage liability covers the $9,000 vehicle repair. If you carry Maryland's minimum 30/60/15 limits, you're fully covered in this scenario.
- You cause a three-car pileup on I-95. Two people are hospitalized with injuries totaling $85,000 in medical costs, and vehicle damage across all three cars reaches $32,000. Your 30/60/15 policy pays $30,000 per injured person and $15,000 for property damage, leaving you personally liable for $25,000 in medical bills and $17,000 in vehicle repairs. The injured parties can sue you for the unpaid balance, and a judgment can attach to your wages, bank accounts, and property.
- You lose control on ice and crash into your own fence and parked motorcycle. Liability insurance does not pay for damage to property you own. You'll need collision coverage for your vehicle and homeowners or renters insurance for the fence and motorcycle. Liability only covers damage you cause to other people's property.
Who Needs Liability Insurance Insurance?
Every driver in Maryland must carry liability insurance to register a vehicle and drive legally. You need it if you own a car, lease a vehicle, or regularly borrow someone else's car with their permission. Drivers with assets to protect — home equity, savings accounts, retirement funds — should carry limits well above the state minimum because a serious at-fault crash can result in a lawsuit that attaches to everything you own.
Start with Maryland's minimum 30/60/15 limits only if you have no assets and can't afford higher premiums. If you own a home, have retirement savings, or earn a wage that could be garnished, carry at least 100/300/100 limits to protect yourself from a lawsuit after a serious crash. Calculate your total assets, then set your bodily injury limit at or above that figure — that's the amount a judgment could take from you if your liability coverage falls short.
How Much Does Liability Insurance Insurance Cost?
Liability-only coverage in Maryland typically costs $45–$85 per month, or $540–$1,020 annually, for drivers with clean records carrying state minimum limits. Increasing limits to 100/300/100 adds approximately $15–$30 per month.
- Your driving record directly affects liability premiums — a single at-fault accident increases rates by 20–40 percent for three to five years.
- Coverage limits you select determine base cost — doubling bodily injury limits from 30/60 to 100/300 typically raises premiums by 25–35 percent.
- Where you live in Maryland influences rates because urban areas like Baltimore see higher claim frequency and severity than rural counties.
- Your age and gender affect pricing — male drivers under 25 pay 50–80 percent more than drivers over 30 with identical records.
- Credit-based insurance scores impact rates in Maryland, with poor credit adding 30–70 percent to liability premiums compared to excellent credit.
- Annual mileage matters because higher exposure increases accident probability — commuting 30 miles daily costs more than driving 5,000 miles per year.
