Term life and accidental death are two different types of life insurance plans.
Term insurance pays out a death benefit if you die from an accident, or natural causes.
Whereas, accidental death coverage only pays out a death benefit if the insured person dies from an accident.
And, with accidental death plans the insured must die usually within 3 months of the accident in order for accidental death to pay out a death benefit.
