Incontestability refers to a clause in insurance policies that prevents insurers from contesting the validity of a policy after it has been in force for a certain period, usually two years.

The waiver of premium rider is a provision that allows the policyholder to have their premiums waived if they become disabled and unable to make payments. While this rider offers significant financial relief, it does not pertain to the accidental death benefit and does not involve additional payouts related to death.

Guaranteed insurability is a rider that allows policyholders to purchase additional coverage at specified times without undergoing medical underwriting. This option provides flexibility in adjusting coverage based on changing needs but has no connection to accidental death benefits or the concept of double indemnity.
