You may wish to make changes to your existing car insurance policy, and these changes are done through an endorsement. An endorsement is a written evidence of the changes made in the policy. If you need to make any changes then you can submit a letter to the insurer with the necessary proofs. This helps you obtain an endorsement, which can affect the premium to be paid for the policy.

The add-on covers are meant to support car insurance plans adequately. Some of the add-on covers are zero-depreciation, invoice cover, engine and electronic circuit cover and No Claim Bonus Protector cover. A zero depreciation cover ensures that the insured can have a full claim on the value of the parts without deductions for standard depreciation that are replaced after an accident. The invoice cover ensures that you will be reimbursed the ‘on road price’ in case the car gets stolen or has a total loss due to a major accident. The engine and electronic circuit cover offers protection during flooding. The No Claim Bonus cover helps you retain the NCB benefit even after one claim has been made during the year.

The simplest way to lower your monthly rate is to raise your deductible. You’ll have to pay more out of pocket if you ever file a claim, but that can be worth it depending on your driving record and your saving habits. You can also look at the discounts your insurer offers and make adjustments to qualify for them. Things like adding safety features, opting for an e-bill, or taking a safety course are all simple actions that qualify as discounts for some companies.
If your car is not insured and involved in an accident, you might have to pay to rent a car or cover repairs yourself. Comprehensive and Collision coverage as part of your car insurance policy is a much better value because, even if you're not involved in an accident, you can still be protected against theft, fire, vandalism and windshield damage.
