What does stacked uninsured motorist coverage mean and will it get your car fixed by insurance?

"Stacked" refers to uninsured motorist coverage, not to liability or physical damage coverage. In essence, if there are two cars in a household, both with insured motorist coverage, the uninsured motorist limits of the cars can be "stacked"--added together. Naturally, this will only make a difference if the severity of the injury and the clarity of the liability is such as to warrant that size of a payment to the insured. Keep in mind that the assessment of damages by an insurer in an uninsured motorist claim is similar to that done by a liability insurer in a third-party claim. Note also that some states have "anti-stacking" statutes which prohibit the stacking of ininsured motorist limits.
