How Much Car Insurance Do I Need?

1. Meet the legal requirement first

The NAIC says most states require auto liability coverage for bodily injury and property damage. It also notes that 49 states plus the District of Columbia require auto liability, while New Hampshire uses a financial-responsibility framework.

Because minimum limits vary, verify current requirements with your state insurance regulator or DMV rather than relying on a national table that can become stale.

2. Decide how much liability protection you can justify

Liability coverage protects against covered injuries and property damage you cause to others, subject to the policy limits. A minimum-limit policy may leave substantial personal exposure after a severe crash.

There is no universal correct limit. Think about assets, income, risk tolerance and umbrella-insurance needs, and obtain licensed professional guidance for individualized recommendations.

3. Protect the vehicle when it matters

Collision generally covers covered damage from a crash or rollover, while comprehensive covers non-collision events such as theft, hail, fire, flood or animal strikes. If a vehicle is financed or leased, the lender or lessor commonly requires both.

For an older paid-off vehicle, compare the premium and deductible with what the car is worth and what you could afford to replace from savings.

4. Review uninsured, medical and deductible choices

Uninsured/underinsured motorist coverage is required in some states and optional in others. PIP or medical-payment coverage can also be state-specific. A higher deductible can reduce premium but requires more cash after a claim, so the deductible should be compatible with your emergency fund.

Compare coverage limits with the loss you could face

Use the same liability limits, deductibles and optional coverages when requesting quotes. A cheaper quote may simply transfer more risk back to you. NAIC guidance explains that liability and uninsured or underinsured motorist protections address different losses. Your state’s requirements and the policy wording determine what applies.

For example, a split liability limit written as 100/300/50 commonly means up to $100,000 for bodily injury to one person, $300,000 for bodily injury in one accident and $50,000 for property damage. Those are illustration limits, not a recommendation for every driver. Ask the insurer to explain exactly how the quoted limits work.

Choose a deductible you could actually pay

Compare the premium savings from a higher deductible with the additional cash you would need after a covered claim. If increasing a deductible from $500 to $1,000 saves an illustrative $100 a year, the extra $500 of exposure equals five years of that saving before any claim. Keep the deductible in accessible cash.

Review the policy after a vehicle purchase, a move, a change of drivers or a material change in household finances. Collision, comprehensive, liability and roadside assistance solve different problems. For broader household protection, use the insurance hub to compare policy types rather than treating auto coverage as a complete insurance plan.
