A widely recommended and solid starting point for liability coverage is 100/300, meaning $100,000 per person and $300,000 per accident. This baseline significantly surpasses most state minimums to better protect your assets from the high costs of a serious accident.
Choosing lower limits often exposes you to substantial financial risk. Bodily injury and property damage costs from collisions can escalate far beyond minimal coverage. For instance, the average bodily injury liability claim now exceeds $24,000, and severe injuries easily reach hundreds of thousands in medical expenses, lost wages, and fees. A 100/300 policy provides a crucial buffer against these common but devastating costs.
To illustrate the gap between common minimums and recommended coverage, consider this data:
| Coverage Type | State Minimum (Example: CA) | Recommended Minimum | Average Bodily Injury Claim* |
|---|---|---|---|
| Per Person | $15,000 | $100,000 | $24,000+ |
| Per Accident | $30,000 | $300,000 | N/A |
| Property Damage | $5,000 | $100,000 | $5,300+ |

While 100/300 is a strong benchmark, your specific situation dictates the ideal level. The primary purpose of liability insurance is to shield your personal assets—savings, home, future income—from being seized to settle claims that exceed your coverage. If your net worth is higher, consider increasing to 250/500 or adding an umbrella policy for multi-million dollar protection. Conversely, if you have very few assets, the cost-benefit analysis might differ, though carrying only state minimums remains a high-risk strategy.
Market data shows policies with 100/300 limits are among the most commonly purchased by conscientious drivers, indicating its acceptance as a standard of financial responsibility. Ultimately, consulting with an insurance agent to review your asset profile and risk exposure is the most reliable method to finalize your decision.

As a parent with a teen driver, my agent was adamant: never stick with just state minimums. We went with 100/300. Her point was simple—if my kid causes an accident, our family’s savings and our home could be on the line for decades. The extra $20 or so a month for that higher coverage is peace of mind. It’s not just about today’s repair bills; it’s about protecting our family’s future financial stability from a single mistake. For us, it’s a non-negotiable part of responsible parenting.

From a perspective, liability coverage is a defense against catastrophic loss. The 100/300 guideline exists because the probability of a multi-vehicle, injury-causing accident, while low, carries an exceptionally high financial severity. Your coverage limit should act as a shield for your net worth. I advise clients to match their liability limits to their total tangible assets. For many, 100/300 aligns with that threshold. It is a cost-effective form of risk transfer, preventing a litigation event from derailing long-term financial goals. Insuring for the worst-case scenario is prudent economics.

I used to buy the cheapest possible until I saw a friend get sued after a fender bender. His low limits didn’t cover the other driver’s whiplash claim and lost wages. He had to settle out of his own pocket for years. Now I carry 100/300. It doesn’t cost much more monthly, but the protection difference is huge. It covers the real-world costs of accidents, not just the bare legal minimum. Don’t learn this lesson the hard way. Spending a bit more now can save you from financial ruin later.

Having worked in auto , I’ve seen firsthand what happens when coverage is inadequate. Modern medical treatments and car repair technology are expensive. A broken leg from a crash can lead to $80,000 in bills before you even consider pain and suffering or lost income. Most state minimums, like 25/50, are exhausted almost immediately. The 100/300 benchmark is popular for a reason—it realistically covers a broad range of serious single-accident scenarios. It’s the level where I’ve seen policies actually perform their intended function: fully resolving claims without forcing the at-fault driver into personal bankruptcy. My professional opinion is to treat it as your absolute minimum.
