Car insurance explained

Car insurance is the largest recurring cost of driving in the U.S. for most new arrivals — frequently more than the car payment. It is also the one people buy fastest and understand least.

New-arrival cost

Often $1,500–$3,500 a year, falling sharply after 2–3 clean years

Required

Liability coverage in nearly every state

Far above the legal minimum — see below

What each coverage actually does

Liability — pays for the damage you cause to other people. It never repairs your own car. Written as three numbers, for example 25/50/25:

• $25,000 for injury to any one person
• $50,000 for injuries in one accident in total
• $25,000 for damage to other people's property

Collision — repairs your car after a crash, whoever was at fault. Required if the car is financed or leased.

Comprehensive — everything that is not a crash: theft, fire, flood, hail, vandalism, a deer, a rock through the windscreen.

Uninsured / underinsured motorist (UM/UIM) — pays you when the driver who hit you has no insurance or nowhere near enough. Roughly one driver in eight in the U.S. is uninsured; in some states it is closer to one in four.

PIP or Medical Payments — your own medical costs regardless of fault. Required in no-fault states, optional in most others.

Rental reimbursement and roadside assistance — small add-ons; useful if you have no second car.

The state minimum is a trap

Every state's legal minimum was set decades ago and has not kept pace with what cars and medical treatment now cost. A moderate injury claim exhausts a $25,000 limit almost immediately — and you are personally liable for everything above your limit. In the U.S. that means your wages and assets.

A widely used benchmark is 100/300/100 with matching UM/UIM. The difference in premium between that and the bare minimum is usually small; the difference in exposure is your entire financial life.

No-fault states

In about a dozen states, each driver's own policy pays their medical bills regardless of who caused the crash, and there are limits on when you may sue. This changes what coverage you need — PIP is mandatory and often the most important part of the policy. Check which system your state uses before choosing limits.

What determines your price

Factor	Notes
Driving record	The dominant factor once you have one
Years licensed	A foreign licence usually counts for little — this is why year one is expensive
ZIP code	Varies enormously, sometimes street by street
Credit-based insurance score	Used in most states, banned in a few, and often worth more than your driving record
Vehicle	Repair cost and theft rate, not sticker price
Annual mileage	Low mileage is a real discount
Continuous coverage	A gap of even a month raises prices for years

Getting a fair price in your first year

1. Ask your previous insurer for a letter of experience before you leave your home country — years insured, claims made. Several U.S. insurers will credit it. Ask before buying, not after.
2. Get five quotes. The spread between insurers for the identical driver is routinely 2–3×, and the cheapest one changes as you build a record — re-shop every renewal.
3. Use an independent broker as well as direct quotes. They quote several carriers at once; captive agents sell one.
4. Never let coverage lapse, even for a few days between cars. Insurers treat a gap as a risk signal.
5. Ask for every discount by name: defensive driving course, telematics/usage-based programme, multi-policy bundle with renters' insurance, paid in full, paperless, low mileage, good student.
6. Raise the deductible to $1,000 only if you actually have $1,000 available. A high deductible you cannot pay means an unrepaired car.

SR-22

If you are convicted of driving uninsured, a DUI, or certain other offences, the state may require an SR-22 — a filing your insurer makes confirming you carry coverage. It is not insurance itself; it marks you as high-risk and roughly doubles premiums for the years it applies.

Practical points people get wrong

• Coverage generally follows the car, not the driver. If you lend your car to a friend and they crash it, your policy and your premium take the hit.
• A household member who drives your car must usually be listed on the policy. Leaving someone off to save money gives the insurer grounds to refuse the claim.
• Keep proof of insurance in the car and on your phone. It is the first thing an officer asks for.
• Telling the insurer you moved matters — rates are set by garaging address, and a wrong one can void a claim.

Once the policy is in force, read what to do after a car accident before you need it.
