Silver Alert dynamic sign boards: which statement is correct?

• A. 60 years or older with irreversible deterioration
• B. 18-59 years under extraordinary circumstances
• C. Both A and B apply
• D. Neither age qualifies

Answer: (C)

Silver Alert dynamic sign boards are used when a missing person is considered at risk and needs rapid public awareness. The important point is that eligibility isn’t limited to a single age category; it can be based on vulnerability and circumstances, not just age alone. In some policies, an elderly person (60 or older) with irreversible deterioration qualifies because their condition makes them especially vulnerable and hard to locate. In other cases, a younger adult (18–59) may also qualify if there are extraordinary circumstances that put them at significant risk.

So, both kinds of criteria exist in practice, depending on the jurisdiction, which is why the statement about 60+ with deterioration and the statement about 18–59 under extraordinary circumstances can both apply. The option saying neither age qualifies would ignore these risk-based criteria, and the option saying only one age group qualifies would be too restrictive given the broader definitions used in some areas.
