Insurance is just a risk transfer mechanism wherein the financial burden which may arise due to some fortuitous event is transferred to a bigger entity called an Insurance Company by way of paying premiums. This only reduces the financial burden and not the actual chances of happening of an event. Insurance is a risk for both the insurance company and the insured. The insurance company understands the risk involved and will perform a risk assessment when writing the policy. As a result, the premiums may go up if they determine that the policyholder will file a claim. If a person is financially stable and plans for life's unexpected events, they may be able to go without insurance. However, they must have enough to cover a total and complete loss of employment and of their possessions. Some states will accept a surety bond, a government bond, or even making a cash deposit with the state.
Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
