What does full coverage car insurance actually mean?

Full coverage is not a defined product and appears in no policy document as a coverage type. In common usage it means liability, which is legally required in most states and pays for injury and damage you cause to others, plus collision, which pays for damage to your own vehicle in a crash regardless of fault, plus comprehensive, which covers non-collision events such as theft, fire, hail, flood, vandalism, and animal strikes. Someone telling you they have full coverage has told you very little about their actual protection.

What it commonly does not include is where people get hurt. Gap insurance covers the difference between what you owe on a loan or lease and the vehicle's actual cash value if it is totaled, which matters enormously in the first years of a loan when depreciation outpaces principal. Rental reimbursement pays for a car while yours is repaired. Roadside assistance and new car replacement are separate add-ons. Uninsured and underinsured motorist coverage protects you when the at-fault driver has no insurance or too little, which given that roughly one in eight drivers is uninsured nationally is among the most valuable coverages available and is optional in many states.

The judgment call most owners face is when to drop collision and comprehensive on an older vehicle. The rough test is comparing the annual premium for those coverages plus your deductible against the vehicle's actual cash value, since the insurer will never pay more than the car is worth. When a car is worth three thousand dollars and collision plus comprehensive costs six hundred a year with a thousand-dollar deductible, the math has turned. Also note that liability limits deserve more attention than they get, since state minimums are frequently far below the cost of a serious injury, and the gap between minimum limits and substantially higher ones is often a modest premium difference against a very large exposure difference.
