Final answer:
The insured with stacked uninsured motorist coverage of 25/50 on each of two vehicles would have a total available coverage of 50/100 in the event of an accident with a hit & run driver.
Step-by-step explanation:
An insured with stacked uninsured motorist coverage of 25/50 limits on each of two vehicles would have a combined coverage amount in the event of an accident with a hit & run driver. Stacking means that the coverage limits for multiple vehicles can be combined (or "stacked") for a larger total coverage amount. Therefore, with two vehicles having 25/50 limits, the available uninsured motorist coverage in this scenario would be 50/100 when stacked. This effectively doubles the individual per-vehicle coverage amounts to protect against drivers who do not have sufficient insurance coverage.
