There is really no such thing as "full coverage." No insurance company should advertise full coverage, because it’s impossible to buy a car insurance policy where you are fully covered against every exposure.
Sometimes people say they’ve added full coverage to their car, or that their lienholder requires full coverage, when they are just talking about having physical damage coverages of collision and comprehensive on their policy.
What most drivers and insurance agents refer to as full coverage is a car insurance policy that includes state-mandated car insurance coverages (this usually is bodily injury liability and property damage liability but also may include uninsured motorist and personal injury protection), along with physical damage coverages of collision and comprehensive.
Bodily injury liability covers other people’s bodily injuries and death for which you are responsible. Property damage liability covers you if your car damages someone else’s property. These coverages come with maximum limits that you choose at the inception of your policy.
Liability coverages don’t protect your car in any way, so that is why you purchase physical damage coverages. Collision insurance covers damage to your automobile caused by a collision with another object or by upset. Comprehensive insurance covers damage to your vehicle for damages caused by things other than collision, such as vandalism, theft, or glass breakage.
Most lienholders require physical damage coverage if you are financing or leasing your vehicle. These coverages each come with a deductible, an amount due before your insurance benefits kick in. (See "Will higher deductibles save you money")
Whatever car insurance coverages you have are subject to the guidelines and terms of your policy, especially with regards to the payment of claims. We personally try not to use the term full coverage because it can be misleading and make policyholders upset when they come across a situation that cannot be claimed or that they feel is only partially covered.
