Car insurance
Every US state ties driving to insurance, and the vocabulary is unlike anywhere else in the world. This hub explains how American auto insurance works, what each coverage actually pays for, how premiums are set, and exactly what to do after an accident — in plain English, with no sales pitch.

US360 is an independent education publisher. We do not sell insurance, quote policies, or receive commission from carriers. Coverage requirements and rates are set by state law and individual insurers — always confirm the details with your state insurance department and read your own policy documents before you decide.

How the American system works, the vocabulary, and what the law actually requires.
What each coverage pays for, what it excludes, and how limits and deductibles interact.
How premiums are priced, how to compare quotes honestly, and where discounts really come from.
What to do at the scene, how a claim proceeds, and how to push back when it stalls.

Proof of insurance, lapses, cancellations, and how to avoid insurance scams.
Pricing
Rating factors carriers use, and whether you can influence them.
| Factor | Effect | In your control |
|---|---|---|
| Where you park overnight | ZIP-level claim, theft, and repair-cost data can move a premium more than any other single factor. | Not quickly |
| Driving record | At-fault crashes and moving violations typically affect pricing for three to five years. | Yes |
| Age and years licensed | Newly licensed drivers of any age pay more until a US driving history exists. | Not quickly |
| Vehicle make and model | Repair cost, parts availability, theft rate, and safety ratings all feed the price. | Yes |
| Annual mileage and use | Commuting and business use price higher than occasional personal use. | Yes |
| Coverage choices | Higher limits cost more; higher deductibles cost less but raise your own exposure. | Yes |
| Continuous coverage | An unbroken insurance history is one of the strongest discounts available. | Yes |
| Credit-based insurance score | Used in most, though not all, states — several states restrict or ban it. | Yes |
| Claims history | Frequency matters more than size; several small claims can cost more than one large one. | Yes |
Emergency
Nine steps that protect your safety, your legal position, and your claim. Save this offline before you need it.
Step 1
Leaving the scene of a crash is a criminal offence in every state.
Step 2
An official report number makes a claim dramatically easier to settle.
Step 3
Name, phone number, insurer, policy number, and plate number — nothing more.
Step 4
Photographs are the single most valuable thing you can produce later.
Step 5
Soft-tissue injuries often appear hours later, and a gap in treatment weakens a claim.
Step 6
Report even when you are not at fault and even when you may not claim.
Step 7
You are not required to give the other carrier a recorded statement.
Step 8
You generally choose your own repair shop, whatever a carrier suggests.
Step 9
Every state has an insurance department that accepts consumer complaints for free.
State by state
Minimum liability limits, whether PIP is mandatory, whether uninsured motorist coverage must be offered, how proof of insurance is checked, and the penalties for driving uninsured are all state law. Two neighbouring states can differ dramatically.
Every state runs a department of insurance that publishes the current minimums, licenses carriers, and accepts consumer complaints free of charge. That department, not a comparison site, is the authoritative source.
