"Full coverage" is not a legal term - it usually means liability plus collision and comprehensive. State minimum liability covers others when you are at fault, but it often will not repair or replace your car.
Liability coverage
Pays bodily injury and property damage you cause to others, up to your limits. Every state requires some form of liability (or an alternative). Minimum limits can leave you personally exposed after a serious accident.
Split limits vs. combined single limit
Many policies use split limits (for example, bodily injury per person / per accident / property damage). Ask your agent or quote tool to explain what each number means for a multi-car crash.
Collision and comprehensive
Collision helps repair your vehicle after a crash with another car or object. Comprehensive typically covers non-collision events like theft, vandalism, hail, or animal strikes. Lenders and lessors almost always require both.
Deductibles matter
Higher deductibles usually lower your premium, but you pay more out of pocket if you file a claim. Pick an amount you could actually afford tomorrow without draining emergency savings.
Uninsured and underinsured motorist
These coverages help when the other driver has little or no insurance. In many states they are optional; in others they are required or strongly recommended. Review them when you compare quotes, not only at claim time.
Choosing wisely for your situation
If your car is newer or financed, full coverage is usually worth comparing. If the vehicle is older and paid off, some drivers raise deductibles or drop collision - but only after weighing repair costs versus premium savings.
Revisit your mix at renewal: mileage changes, a paid-off loan, or a move to a new ZIP can all change the math.
