As required by law, drivers must carry at least a minimal amount of bodily injury liability and property damage liability coverage. A few states do not require both or have other limitations. Each state sets its minimum requirement for each type of coverage. Even in “no-fault” states, liability coverage is all but essential. No-fault laws were established to reduce or eliminate ordinary injury lawsuits affixed with low-dollar price tags and an overwhelming number of claims for pain and suffering. Still, no-fault laws do not protect the insured from million-dollar injury lawsuits stemming from seriously injured third parties. Both types of third-party insurance are important, specifically for individuals, such as homeowners, with substantial assets to protect. The more money and assets an insured has, the higher the limit should be for each type of liability coverage.
Pretty much all drivers are subject to the risks mentioned above, so the short answer to the question is, "Almost everybody." Take animal collisions, for example. According to the Insurance Institute for Highway Safety, there are more than 1.5 million deer-vehicle collisions every year, resulting in over $1 billion in vehicle damage — and that's just deer-vehicle collisions.
If you have paid off your car, comprehensive coverage is optional. It may be a good idea to find out the Kelley Blue Book value of your vehicle. Would you be able to pay that amount to repair or replace your vehicle if it were stolen or damaged in an accident? If you can't afford to pay much out of pocket, then buying optional coverages, like comprehensive coverage and collision coverage, may be a smart investment.
