Florida Silver Alert: Criteria, How to Activate It, and What Families Should Know

What a Florida Silver Alert Is

A Silver Alert is a statewide notification system that activates law enforcement, highway message signs, and media broadcasts to locate a missing person with a documented cognitive impairment — typically Alzheimer's disease or a related dementia. Florida's Silver Alert program is administered by the Florida Department of Law Enforcement (FDLE) and was one of the first in the country.

It's not the same as an AMBER Alert. Silver Alerts target adults with verified cognitive conditions, not abducted children. The system activates different resources, and the criteria are specific.

The Activation Criteria

The core criteria include age, documented cognitive impairment, and a missing-person safety concern. Vehicle information matters for the highway-sign component:

Age requirement: The missing person must be 60 years or older. Adults aged 18 to 59 can qualify if they have a verified, irreversible deterioration of intellectual faculties — meaning a documented medical diagnosis of dementia, Alzheimer's, or a comparable cognitive disorder.

Documented cognitive impairment: A family member or caregiver cannot simply report that the person seems confused. There must be a clinical diagnosis on record — an Alzheimer's or dementia diagnosis from a physician. This is one reason neurologists and primary care doctors emphasize documenting cognitive decline formally: without a diagnosis in the system, the Silver Alert criteria aren't met.

Missing and at risk: The person must be reported missing and believed to be in danger due to their cognitive condition. A person who left voluntarily and has no cognitive impairment doesn't qualify.

Vehicle with an identified license plate: This is the criterion that surprises most families. The dynamic highway message signs — the electronic signs on Florida interstates and major highways — can display a vehicle description and tag number when the person is traveling in a motor vehicle with an identified license plate. If the missing person is on foot or the vehicle's plate is unknown, the highway-sign component cannot be activated.

Law enforcement can still issue a local Be On the Look Out (BOLO) bulletin for a missing person on foot; the highway-sign component requires a known vehicle and plate number.

How to Activate a Silver Alert

You don't call FDLE directly. The process starts with local law enforcement:

1. Call 911 or your local police/sheriff's department to report the missing person. Provide the person's name, physical description, medical diagnosis, vehicle description and license plate, and last known location and direction of travel.

2. The local agency files a missing person report and evaluates whether the Silver Alert criteria are met. If they are, the agency contacts FDLE to request activation.

3. FDLE issues the Silver Alert through the Florida Crime Information Center. The alert goes out to all law enforcement agencies statewide, activates highway message signs along likely travel routes, and distributes the bulletin to participating media outlets.

4. The alert remains active until the person is found or law enforcement determines it should be deactivated.

The process can move quickly, but timing depends on how fast the local agency verifies the criteria and contacts FDLE. Having the vehicle information and medical documentation ready helps the agency evaluate the report.

What to Prepare Before a Crisis

Wandering is not a question of if but when for many dementia patients. Families who are prepared before the first episode respond faster and give law enforcement better information:

Keep a current photograph of your parent — high resolution and showing their face clearly. Law enforcement needs a photo that looks like how the person appears today, not five years ago.

Document the medical diagnosis. Have a copy of the physician's diagnostic report accessible — not filed away in a medical records office. If the local agency needs to verify the cognitive impairment criterion, you want that documentation in hand.

Record vehicle details. License plate number, make, model, year, color, and any distinguishing features (bumper stickers, dents, aftermarket modifications). Write it down and keep it where you can find it under stress.

Note their patterns. People with dementia often wander toward familiar places — their childhood home, a former workplace, a church they attended for decades. Share these locations with law enforcement when you report a wandering episode.

Consider a GPS tracker. A personal GPS device (worn as a watch, pendant, or clipped to clothing) or a vehicle-mounted tracker can give law enforcement a real-time location instead of a search area. Local sheriff-sponsored programs and electronic tracking services such as SafetyNet by LoJack may offer additional support.

Our Florida Dementia Care Guide includes a pre-filled Silver Alert information card designed to be completed before a crisis — so when you're calling 911 at 2 AM because your parent drove away in the middle of the night, every detail law enforcement needs is already written down.
