Full Coverage vs Liability Only: Which Do You Need?

Understanding the Two Main Options

Every state requires at least liability insurance, but full coverage adds comprehensive and collision protection for your own vehicle. The question is: when is the extra cost worth it?

Liability Only

Liability insurance covers damage you cause to others — their medical bills and property damage. It does NOT cover your own vehicle or injuries. This is the cheapest option and the legal minimum in most states.

Best for: Older vehicles (10+ years), cars worth under $5,000, drivers on a tight budget, vehicles that are paid off.

Full Coverage

Full coverage adds collision (covers your car in an accident) and comprehensive (covers theft, weather, animals, vandalism). Some definitions also include uninsured motorist and medical payments coverage.

Best for: Newer vehicles, cars with loans or leases (required by lender), vehicles worth over $10,000, drivers who can't afford to replace their car out of pocket.

The Cost Difference

On average, full coverage costs 50-70% more than liability only. Our state data shows the national average for liability is significantly less than full coverage. Check your state's specific numbers.

The Break-Even Calculation

A simple rule: if your annual full-coverage premium exceeds 10% of your car's value, liability-only may make more financial sense. For example, if full coverage costs $2,000/year and your car is worth $8,000, you're better off saving the difference and self-insuring.
