Car insurance is one of those expenses most people set up once and never revisit. That’s a mistake — both for your wallet and your protection. Here’s exactly what the different types of coverage mean, what’s legally required, and where most people are either over-insured or dangerously under-insured.
The coverage types explained
- Liability: Covers damage you cause to other people and their property. Required in almost every US state. Expressed as three numbers — e.g. 100/300/100 means $100k per person bodily injury, $300k per accident, $100k property damage.
- Collision: Covers damage to your own car from an accident, regardless of fault. Required if you have a car loan or lease.
- Comprehensive: Covers non-collision damage — theft, weather, fire, animals. Also required by most lenders.
- Uninsured/Underinsured motorist: Covers you if the at-fault driver has no insurance or insufficient coverage. Highly recommended — roughly 1 in 8 US drivers is uninsured.
- Personal injury protection (PIP): Covers medical expenses for you and passengers regardless of fault. Required in no-fault states.
State minimums are not enough
Every state sets minimum liability requirements, but these minimums are dangerously low. A state minimum of 25/50/25 means your insurance covers only $25,000 in property damage per accident. A single new car costs $40,000+. If you cause an accident involving an expensive vehicle, you’re personally liable for the difference. Most financial advisors recommend at least 100/300/100 liability coverage — the cost difference is typically $10–$20/month.
When to drop collision and comprehensive
If your car is worth less than $4,000–$5,000, collision and comprehensive coverage may cost more than the car is worth. A simple rule: if your annual premium for these coverages exceeds 10% of your car’s current value, consider dropping them. Use Kelley Blue Book to check your car’s current market value before deciding.
How to save $500 a year on car insurance
- Shop every renewal: Loyalty rarely pays — insurers often give better rates to new customers
- Bundle with renters or home insurance: Multi-policy discounts typically save 10–15%
- Raise your deductible: Going from $500 to $1,000 deductible can cut premiums 15–30%
- Ask about discounts: Good driver, good student, low mileage, and defensive driving discounts are rarely applied automatically
- Use a comparison site: NerdWallet, The Zebra, or Policygenius compare multiple insurers in minutes
The coverage most people skip that they shouldn’t
Uninsured motorist coverage is consistently undervalued. It costs very little — typically $5–$15/month — and protects you from one of the most common and frustrating scenarios: being hit by a driver with no insurance. In states with high uninsured driver rates (Florida, Mississippi, New Mexico have rates above 20%), this coverage is essential.
