Plate readers in Lemhi County

A license plate reader is a camera that photographs every vehicle that passes it, reads the plate, and files the number with the time and the place. It does that to everyone who drives past, not to suspects.

Lemhi County has about eight thousand residents and two main roads. Volunteers have mapped one reader here, on Idaho 28 between Leadore and Gilmore, tagged as Flock Safety equipment with no operator recorded, standing beside an Idaho Transportation Department traffic and weather camera.^[4] That is a community report, not an agency’s account, and nobody has published an agency’s account.

What the county’s own record says

Plate readers appear twice in the Board of County Commissioners’ published record, both times in 2026.

On 23 February the Sheriff, in a department update, reported that dispatch is in the process of installing new consoles, that the city has received a grant to install license plate readers but he is unsure how many will be installed or where they will be located, and that license plate readers have been helpful in investigating drug related crimes and missing persons cases.^[1]

Read that again slowly. The county’s own sheriff, whose office dispatches the city’s police department, told his commissioners that he did not know how many readers the city was installing or where they would go.

Two weeks later, on 9 March, the Board’s agenda carried an item reading “LICENSE PLATE READER DISCUSSION”, printed between the hospital bond payment and commissioner updates.^[2] The minutes of that meeting record no plate reader discussion at all. They run from the hospital’s MRI project to commissioner updates to executive session.^[6]

An item on an agenda is not a decision, and in this case it is not even a discussion anyone can read. What the commissioners said about plate readers on 9 March 2026, if they said anything, is not in the public record.

The reader on the highway

The mapped reader is about 35 miles south of Salmon, near the road to the Montana line. The only plate reader money named anywhere in the county’s record is the city’s grant, and Salmon is the other direction.

So the operator of that reader is unestablished. It could be the city’s, it could be the Sheriff’s, it could belong to the state. No county document we could read names an owner, a vendor, a price, a count or a location for any plate reader, and neither the county nor the city publishes a policy for one.

What Idaho law asks

Idaho has governed plate readers by statute since 1 July 2025.^[5] Section 49-1432 of the Idaho Code lets an agency use a reader for law enforcement or traffic flow analysis. Where it is used for law enforcement, it limits the device and its data to investigating felony or misdemeanor crimes or traffic accidents, or to searching for missing or endangered persons, and it bars using them to enforce traffic infractions unless an accident is involved.

It asks for record keeping too. Access must be limited to authorized personnel with access controls. Every authorized user must have training in data privacy, legal compliance and ethical use. Every access and every query must be logged with the user’s identity, the date, the time and the purpose. The agency must audit those logs twice a year.

The statute says nothing about how long the reads may be kept. That is the gap every Idaho agency’s retention choice sits in, and no agency here has published a choice.

What this page cannot tell you

We can tell you that a reader stands on Idaho 28, that the City of Salmon has a grant for more, and that the county’s sheriff told his commissioners he did not know the details. We cannot tell you who owns the one on the highway, how many the city bought, where they are, what they cost, how long the reads are kept or who else can search them.

Those questions belong to two rooms. The Board of County Commissioners meets on the second and fourth Monday of the month at the Brooklyn Annex, 200 Fulton Street in Salmon. The Salmon City Council, which holds the grant, publishes its agendas and minutes on the city’s website and answers at 208-756-3214.
