There are lots of things that could trigger the trip cancellation/interruption clause in your coverage, but basically they boil down to natural disasters, sickness or injury, crimes, or work-related reasons.
If you, a family member or a traveling companion encounter any of these during your trip (or back home while you’re traveling) and you’re forced to cancel or interrupt your trip, there’s a good chance your ExactCare trip cancellation/interruption coverage would be triggered.
