The Full Coverage Decision Point
You own an older car outright, and every six months you look at the premium for comprehensive and collision and wonder if you're overpaying. The car's value dropped again. The coverage didn't get cheaper. You're trying to figure out when to stop paying for coverage that might not pay out more than the car is worth.
The decision isn't about age or mileage alone. It's about the relationship between what the car is worth today, what you'd pay out of pocket after the deductible if you filed a claim, and whether you can afford to replace the vehicle without an insurance payout. Illinois doesn't require comprehensive or collision on any vehicle you own outright, so the choice is entirely yours to make.

$25,000 / $50,000 / $20,000
Illinois requires $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. These limits apply regardless of whether you carry full coverage. Dropping comprehensive and collision removes only the coverage that pays for damage to your own vehicle.

What Full Coverage Actually Protects
Full coverage is shorthand for a policy that includes comprehensive and collision alongside the state-required liability minimums. Comprehensive pays for damage from theft, weather, vandalism, and animal strikes. Collision pays for damage from crashes with another vehicle or object, regardless of fault.
Both coverages pay up to the car's actual cash value, minus your deductible.
Liability coverage stays in place whether you drop full coverage or not. Illinois law requires every registered vehicle to carry at least $25,000 per person and $50,000 per accident in bodily injury liability, plus $20,000 in property damage liability. Those limits protect others when you're at fault. They don't pay for damage to your own car.
The coverage stops making financial sense when the annual premium for comprehensive and collision approaches or exceeds the vehicle's current value minus the deductible.
How to Calculate the Breakeven Point
Start with your car's current market value. Use the private-party value from a pricing guide, not the trade-in value or the price you paid years ago. Subtract your deductible from that figure. The result is the maximum amount the insurer would pay you after a total loss.
Next, add up the annual cost of your comprehensive and collision premiums. Compare that annual cost to the net payout. Many households use that 10 percent threshold as the point where the coverage no longer makes sense, though the exact threshold depends on your ability to replace the car without insurance.

State-Specific Factors That Change the Timing
Illinois is a fault state, which means the at-fault driver's liability coverage pays for damage to your car when someone else causes the crash. If you drop collision and another driver hits you, you file a claim against their property damage liability. That works only when the other driver carries insurance and accepts fault. Illinois has a 15.2 percent uninsured motorist rate, so one in seven drivers on the road has no coverage to pay your claim.
Uninsured motorist property damage coverage is required in Illinois unless you reject it in writing. That coverage pays for damage to your car when an uninsured driver is at fault, up to the policy limit you select. It does not replace collision coverage, because it only pays when the other driver is uninsured and at fault. It won't pay for a single-car crash, a hit-and-run where the other driver is never identified, or damage you cause yourself.
If you drop collision and keep uninsured motorist property damage, you're covered when an uninsured driver hits you. You're not covered when you hit a pole, slide off the road in winter, or cause a crash yourself. The gap matters in a state where winter weather and rural roads create single-vehicle crash risk.

One in seven drivers in Illinois carries no insurance. If you drop collision and an uninsured driver hits you, uninsured motorist property damage coverage pays for your vehicle damage only if you carry it and only up to your selected limit.

When Dropping Coverage Creates Risk
Dropping full coverage makes sense when you can afford to replace the car out of pocket and the annual premium no longer justifies the potential payout. It creates risk when you cannot afford to replace the vehicle and you rely on it for work, medical appointments, or household errands. A total loss without collision coverage means you pay the full replacement cost yourself.
Households that insure multiple vehicles face a different calculation. If you drop full coverage on one car but keep it on another, you still pay for the coverage on the newer or higher-value vehicle. The savings come only from the car you drop. If both cars are older and worth less than the annual premium justifies, you can drop coverage on both, but that leaves the household with no collision protection on any vehicle. One crash can eliminate transportation for the entire household if no car is covered.
Compare Carriers Before You Drop
Before you drop comprehensive and collision, compare what other carriers charge for the same coverage on the same vehicle. Premium varies widely across Illinois carriers. If the lower premium brings the annual cost below the 10 percent threshold, keeping the coverage makes sense.
Illinois licenses 31 carriers that write standard and non-standard auto policies across the state. Not every carrier writes coverage for older vehicles, and some apply surcharges or restrictions based on vehicle age or value. Request quotes from at least three carriers that write policies for your vehicle's age and value range. Compare the combined cost of comprehensive and collision against your car's current value minus the deductible. If switching carriers keeps the annual cost reasonable, you avoid the gap in coverage that comes with dropping it entirely.
