Auto Insurance · Types of coverage
Auto insurance coverage types, explained
Auto insurance is six or seven distinct coverages bundled into one policy. Each does something specific. Here's what each one actually pays for — and which ones you actually need.
Liability coverage
Pays for damages and injuries you cause to others. Required by law in nearly every state.
Liability comes in three parts, often written as a slash format like 100/300/100:
- Bodily injury per person (first number): max paid to one injured person
- Bodily injury per accident (second number): max paid total across all injured people in one accident
- Property damage (third number): max paid for damage to other vehicles and property
State minimums (often 25/50/25) are dangerously low. The modern baseline is 100/300/100. Higher-net-worth households should consider 250/500/100 plus an umbrella policy.
Collision coverage
Pays for damage to your vehicle in a crash — whether you're at fault or not. Has a deductible (typically $250, $500, or $1,000) that you pay before the carrier pays.
Required by lenders on financed vehicles. Optional on owned vehicles, but worth carrying if your car is worth more than ~$3,000.
Comprehensive coverage
Pays for non-crash damage to your vehicle: theft, vandalism, weather (hail, flood, tree falling), animal strikes, glass breakage.
Like collision, it has a deductible. Often sold together with collision as "full coverage" — but they're technically separate coverages.
Uninsured/Underinsured motorist (UM/UIM)
Pays for your damages and injuries if the at-fault driver has no insurance (UM) or not enough insurance (UIM). Roughly 12-15% of drivers nationally are uninsured.
Cheap to add and absolutely essential. Typically match your liability limits — if you carry 100/300/100 in liability, carry 100/300 in UM/UIM.
Some states require UM/UIM; others make it optional. In all cases, declining it is a bad decision.
Personal injury protection (PIP) and Medical payments
Both pay your medical bills (and sometimes lost wages, funeral expenses) regardless of who caused the accident.
- PIP: required in no-fault states. Pays broader benefits including lost wages, replacement services, sometimes funeral expenses.
- Medical payments (MedPay): medical-only, available in fault-based states.
If you have strong health insurance with a low deductible, PIP/MedPay is less critical. If you have high-deductible health coverage or you frequently drive passengers, more PIP/MedPay is genuinely useful.
Optional and add-on coverages
Rental reimbursement: pays for a rental car while yours is being repaired after a covered claim. $30-60/year.
Towing and roadside assistance: covers towing, jump starts, lockout, fuel delivery. $10-30/year — but check if you already have AAA or credit card coverage.
Gap insurance: pays the gap between your loan balance and the car's value if it's totaled. Only relevant if you financed with low down payment or leased.
New car replacement: replaces totaled cars under 1-2 years old with current-year model rather than actual cash value. Useful if you bought new.
Accident forgiveness: waives the first at-fault accident from rate calculation. Usually an upgrade for an additional premium; sometimes earned through claim-free tenure.
Custom equipment / OEM parts: covers aftermarket accessories and ensures OEM (not aftermarket) parts are used in repairs.
Rideshare coverage: bridges the gap between your personal policy and rideshare company coverage when driving for Uber/Lyft.
The structure of a typical policy
A reasonable policy for an adult with assets:
- Liability: 100/300/100 (or higher with umbrella)
- UM/UIM: matching liability
- Collision: $500 or $1,000 deductible
- Comprehensive: $500 or $1,000 deductible
- MedPay or PIP: $5,000-$10,000
- Rental reimbursement: yes if no backup vehicle
- Roadside assistance: only if not covered elsewhere
Skip: anything you don't understand the purpose of. If an agent is pushing an endorsement and can't explain in one sentence what it does, that's a signal.
