Actually, there is no such think, than the full coverage auto insurance. The insurance companies use it and the agents use it, but what does it really mean?
Many people considered full coverage auto insurance - term meaning the physical damage coverage, which includes the collision and the comprehensive coverages.
Usually the collision coverage covers the damages to your car caused in the collision by another party or by upset. And the comprehensive coverage covers damages to your car by theft, vandalism or broken windshield, for instance.
It is usual, that many lienholders require the physical damage coverage for the leased or financed vehicle. Also, if you will lease the vehicle ( rather than to finance it ), you may have to carry the specific amount of liability insurance.
This has two parts, the Bodily Injury Liability Insurance and the Property Damage Liability Insurance. The former covers the bodily injuries or death of other people and the latter, if your car will cause damage to a property, which is owned by somebody else.
Concerning the term "full coverage auto insurance", it is better to be careful and to ask, what the term actually mean.
