Yes, car insurance is legally required in California. The state mandates that all drivers carry a minimum amount of liability insurance. The core requirement is often referred to as 15/30/5 coverage. This means:
You must be able to provide proof of this insurance when registering your vehicle or if a law enforcement officer asks for it during a traffic stop. Driving without insurance can lead to severe penalties, including fines, license suspension, and vehicle impoundment. While this minimum coverage keeps you legal, it's often not enough to fully protect your assets in a serious accident. Most financial advisors recommend purchasing higher limits and considering additional coverage like collision and comprehensive.
| California Minimum Auto Insurance Requirements | Coverage Limit |
|---|---|
| Bodily Injury Liability (per person) | $15,000 |
| Bodily Injury Liability (per accident) | $30,000 |
| Property Damage Liability (per accident) | $5,000 |
| Uninsured Motorist Bodily Injury (per person) | $15,000 |
| Uninsured Motorist Bodily Injury (per accident) | $30,000 |
While liability insurance is the only coverage required by law, California also requires insurance companies to offer you Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverage. These protect you if you're hit by a driver with no insurance or insufficient insurance. You can decline this coverage in writing, but it's a valuable and often affordable addition to your policy.

It’s not just required, it’s a non-negotiable part of driving here. I got a ticket years ago for forgetting to put the new insurance card in my glove compartment. The fine was brutal, and the hassle with the DMV to clear it was worse. Now I just set a calendar reminder for when my policy renews. It’s cheaper to pay the premium than to deal with the state’s penalties. You simply don’t want that headache.

Looking at it purely from a financial risk perspective, the state minimum is a starting point, but it's dangerously low. If you cause an accident with significant injuries or damage to an expensive vehicle, $5,000 in property damage coverage is gone instantly. You would be personally responsible for the rest. I view insurance as asset protection. Carrying higher liability limits, like 100/300/100, is a smart move to shield your savings and home from a lawsuit.

The law is clear: no insurance, no legal driving. But the "why" is about responsibility. If you hit my car, your insurance is supposed to cover the repairs. It protects everyone on the road from each other's mistakes. The minimum amounts are pretty low, though. I always make sure I have more than the minimum, especially for medical costs. Hospital bills can wipe out that $15,000 per person in a heartbeat.
