Florida does not require most drivers to carry bodily injury liability insurance. That means many at-fault drivers have little or no coverage to pay for your injuries. UM/UIM coverage on your own policy steps in when the at-fault driver has no insurance, not enough insurance, or flees the scene in a hit-and-run. Insurers must offer UM coverage. If you declined it, the rejection generally must be in writing. “Stacked” UM can let you combine coverage across multiple vehicles in your household.
