Liability-only policies cover damage you cause to others, but not your own car. Full coverage adds collision and comprehensive protection, covering accidents, theft, weather, and other risks.In Illinois, the average cost of full coverage is $363 less compared to the national average.We recommend carrying at least 100/300/100 in coverage – $100,000 for bodily injury per person, $300,000 per accident, and $100,000 in property damage liability. These limits provide stronger protection in serious accidents that could otherwise exceed state minimums.What is full coverage car insurance?Full coverage car insurance includes bodily injury liability and property damage liability coverage, as well as comprehensive and collision coverage. Collision insurance covers your vehicle if it’s damaged or destroyed in an accident, while comprehensive insurance provides protection against damage that is caused by something other than collisions, such as hail or theft.If you lease or finance your car in Illinois, your lender may ask you to purchase collision and comprehensive insurance beyond the state-mandated liability coverage.The bottom line on saving and staying protectedEveryone wants to save on car insurance, but skimping on coverage can leave you with big bills after an accident.The best approach is to balance affordability with protection.
