Large number of similar exposure units: Since insurance operates through pooling resources, the majority of insurance policies are provided for individual members of large classes, allowing insurers to benefit from the law of large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London, which is famous for ensuring the life or health of actors, sports figures, and other famous individuals. However, all exposures will have particular differences, which may lead to different premium rates.
In many cases, the legal minimum insurance won’t be enough to cover costs if you cause an accident. If you total someone’s luxury car, for example, their repair costs could easily exceed a $25,000 ceiling. Any damage that surpasses your limits has to come out of your own pocket. That’s why for most drivers it’s wise to select higher limits, such as 100/300/50.
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.
