Final answer:
For an accident to involve an uninsured motorist and result in property damage costing more than $500 or someone being injured or killed, the at-fault driver must not have valid automobile insurance coverage.
Step-by-step explanation:
In order for an accident to involve an uninsured motorist and result in property damage costing more than $500 or someone being injured or killed, the condition required is that the at-fault driver who caused the accident does not have valid automobile insurance coverage at the time of the accident.
If an accident occurs and the at-fault driver is uninsured, the injured party may need to rely on their own insurance coverage or pursue legal action to recover damages. Additionally, if the accident results in property damage costing more than $500, the injured party or their insurance company may need to cover the costs.
It is important for drivers to have adequate insurance coverage to protect themselves and others in the event of an accident.
