Getting involved in an accident means facing an unplanned financial crunch. A basic car insurance policy type—the third-party liability insurance—does not provide enough coverage. In fact, even a comprehensive car insurance plan may also miss out on a few crucial liabilities. Add on covers in motor insurance come into the picture when you need extended coverage. Like the name suggests, add-on covers for car insurance offer additional protection to your insured vehicle, which can help you enhance your basic car insurance policy.
