There is no such thing as full coverage. Depending on your state, you can buy all the insurance coverage available and you still wouldn't be fully covered.
Most people use this term to refer to Physical Damage coverage. Physical Damage coverage consists of Collision and Comprehensive coverage. Generally, Collisioncovers damage to your automobile caused by collision with another object or by upset. Comprehensive insurance covers damage to your automobile from vandalism, theft or glass breakage. Most lien holders require physical damage coverage if you are financing or leasing your vehicle.
So, the term came from lien holders saying that your car had to be fully covered instead of just buying the state required coverage or minimum state required coverage.
