State minimum vs. full coverage: what the difference actually costs you

Every state except New Hampshire requires drivers to carry liability insurance, and every state sets a minimum. Those two facts get collapsed into a third that is not true: that the minimum is a recommendation.

It is not. It is a floor set by legislation, and in most states it has not moved in decades while the cost of cars and medical care has.

What the three numbers mean

A limit written as 25/50/25 means:

• $25,000 maximum for bodily injury to any one person
• $50,000 maximum for bodily injury across everyone hurt in one accident
• $25,000 maximum for damage to other people's property

Those are the maximums your insurer pays. Everything past them is yours.

Where the floor is lowest

Pennsylvania requires just $5,000 in property damage liability. The average price of a new vehicle in the United States is many times that. A single at-fault collision with a late-model SUV can exhaust a $5,000 property limit before anyone has looked at the injuries.

Louisiana requires $15,000 per person for bodily injury. One ambulance ride, an emergency room visit, and imaging can pass that before treatment has properly started.

Florida is the unusual case: it does not require bodily injury liability at all for most drivers. A Florida driver meeting the state minimum has $10,000 of personal injury protection for themselves and $10,000 of property damage coverage, and no coverage whatsoever for injuries they cause to another person.

What happens when a claim exceeds your limits

Your insurer pays up to the limit and then stops. The injured party can pursue you personally for the rest. Depending on your state, that can mean wage garnishment, liens, and a judgment that follows you for years.

This is the part that does not appear in the price comparison. A minimum-limits policy is cheaper every month and catastrophically more expensive exactly once.

What "full coverage" actually means

Nothing, legally. It is a shorthand the industry uses, and it usually means liability plus collision plus comprehensive:

• Collision pays for damage to your own car in a crash, regardless of fault
• Comprehensive pays for theft, fire, weather, vandalism, and animal strikes

Neither raises your liability limits. A driver with "full coverage" at state minimum liability is well protected against damage to their own car and barely protected against a lawsuit.

The part worth checking

Raising liability limits is usually one of the cheapest things you can do to a policy. Going from 25/50/25 to 100/300/100 more than quadruples your protection and typically costs a fraction of what people assume, because the expensive part of a policy is the first dollar of coverage, not the last.

That is a specific question worth asking about your own policy: what would it cost to raise the limits? It takes an agent about a minute to answer, and it is the single question most likely to change what you buy.
