If you cancel your car insurance, you will be driving without the assurance of a safety net in the event of an accident. This is a risky decision and is not recommended. Driving without insurance is illegal in many parts of the world, so you need to be aware that there could be penalties for not having valid insurance. You will also be responsible for covering the costs of any damages or injuries sustained should you cause an accident. If you're unable to pay for these costs, you may find yourself facing expensive legal fees or even jail time. Further, if you are involved in an accident with an uninsured driver, you will not have the protection of insurance to help you with any expenses resulting from that accident. In other words, you would be responsible for covering all damages, medical bills, and any legal costs.
