Most people buy auto insurance knowing they need it but not understanding what they're buying. Your auto policy is actually 6+ separate coverages — each protecting you from a different risk. Here's what each one does.
1. Liability Coverage (Required)
Liability pays for damage YOU cause to OTHER people and their property:
- Bodily Injury (BI): Medical bills, lost wages, and pain/suffering for people you injure
- Property Damage (PD): Repair or replacement of vehicles/property you damage
- Shown as: Three numbers like 100/300/100 ($100K per person / $300K per accident / $100K property)
- State minimums: Usually 25/50/25 — dangerously low
- Recommended: At least 100/300/100 — and consider an umbrella policy on top
2. Collision Coverage (Optional but Important)
- What it covers: Damage to YOUR vehicle from hitting something — another car, guardrail, tree, pothole
- What it doesn't cover: Mechanical breakdown, normal wear, maintenance
- Required if: You have a car loan or lease (lender requires it)
- Deductible: Typically $500 or $1,000. Higher deductible = lower premium.
- Drop it when: Your car's value minus deductible is under ~$3,000
3. Comprehensive Coverage (Optional but Important)
- What it covers: Everything that's NOT a collision — theft, vandalism, hail, flood, fire, animal strikes, falling objects, glass breakage
- Sometimes called: "Other than collision" coverage
- Required if: You have a car loan or lease
- Deductible: Typically $250-$1,000. Glass claims often have $0 deductible.
- Pro tip: Comprehensive is usually cheap — $100-$300/year. Worth keeping even on older cars.
4. Uninsured/Underinsured Motorist (UM/UIM)
- What it covers: YOUR injuries and damages when the at-fault driver has no insurance (or not enough)
- Why you need it: ~13% of drivers are uninsured nationally. Higher in FL, MS, NM, MI, TN.
- Cost: Typically $50-$150/year for limits matching your liability
- Required in: About 20 states. Optional but highly recommended everywhere else.
- Also covers: Hit-and-run accidents where the other driver can't be identified
5. Medical Payments / Personal Injury Protection (PIP)
- Med Pay: Covers medical bills for you and passengers — regardless of fault. Usually $1,000-$10,000.
- PIP: Required in no-fault states. Covers medical bills PLUS lost wages, funeral expenses, and essential services.
- Key difference: PIP is broader than Med Pay and required in ~12 states
- Useful because: Pays immediately without waiting for the other driver's insurance to settle
6. Roadside Assistance / Rental Reimbursement
- Roadside: Towing, flat tire, lockout, jump start. Typically $2-$5/month.
- Rental reimbursement: Pays for a rental car while yours is being repaired after a covered claim. $30-$50/day limit.
- Worth it if: You don't have AAA and/or don't have a second vehicle
How Much Coverage Do You Actually Need?
- Liability: At least 100/300/100. If your net worth exceeds $300K, go higher or add umbrella.
- Collision: Keep if your car is worth $5,000+. Choose $500 or $1,000 deductible.
- Comprehensive: Almost always worth keeping — it's cheap.
- UM/UIM: Match your liability limits. Essential protection.
- Med Pay/PIP: $5,000-$10,000 minimum. Higher if you don't have great health insurance.
Bottom line: Don't just buy the state minimum and hope for the best. A single serious accident can cost $200,000+. An independent agent shopping 50+ carriers can find you proper coverage at a competitive price — often saving money compared to direct carriers by finding the right coverage mix.
