Yes, it depends if who caused the accident and if it occurred at the place of employment or not.
The individual/entity that was the cause of the accident. In some instances if they fled the scene or have no insurance the injured party is still protected under their own insurance under uninsured motorist claim.
If you were involved in any type of accident that was caused by another or due to the negligence of someone else and not by your own fault and you have sustained an injury.
