One of the hardest questions in auto insurance is also the most important: how much coverage do you actually need? Buy too little and a single serious accident could wipe out your savings. Buy too much and you are paying every month for protection you will never use. The right answer depends on what you own, what you drive, and how much financial risk you can absorb. Here is a practical framework.
Start with liability — and go above the minimum
Liability coverage pays for the injuries and property damage you cause to others. Every state sets a legal minimum, but those minimums are often dangerously low — sometimes as little as $25,000 per accident for injuries. Modern medical bills and vehicle repairs can blow past that in a single crash, and you are personally on the hook for anything above your limit.
A widely used rule of thumb is to carry enough liability coverage to protect your net worth. Many advisors suggest 100/300/100 limits (that is $100,000 per person, $300,000 per accident, and $100,000 property damage) as a reasonable baseline for most drivers who own assets.
Decide whether you need full coverage
Collision and comprehensive coverage — together called full coverage — pay to repair or replace your own car. Whether they are worth it depends mostly on your car’s value:
- If you have a loan or lease, your lender almost always requires full coverage
- If your car is newer or still valuable, full coverage is usually worth it
- If your car is old and worth only a few thousand dollars, the annual premium may approach the payout you would ever receive — at which point dropping it can make sense
Add uninsured motorist protection
A large share of drivers on the road carry no insurance or too little. Uninsured and underinsured motorist coverage protects you when one of them causes an accident and cannot pay for your injuries. It is inexpensive relative to the protection it provides, and it is required in some states.
Consider your deductible carefully
Your deductible is what you pay out of pocket before insurance kicks in on a claim. A higher deductible lowers your premium but raises your cost if you have an accident. Choose a deductible you could comfortably cover from savings tomorrow — typically $500 or $1,000 for most drivers.
Match optional add-ons to your life
Extras like roadside assistance, rental reimbursement, and gap insurance are cheap individually but add up. Add the ones that fit your situation and skip the rest. Gap insurance, for example, matters most if you owe more on your car than it is currently worth.
The bottom line
A solid policy for most drivers means strong liability limits, full coverage if the car warrants it, uninsured motorist protection, and a deductible you can actually afford.
