I drive on I-5 in California, and the exit signs posts if there is a jail, state mental hospital, prison, detention center at that particular off ramp. Is there a policy where this is required? Why are incarceration centers posted on freeway exits?
edit: Can you please cite a policy that requires these detention centers to be posted? Is it a federal policy or a California State policy?
For people who want to visit someone in those facilities, perhaps.
But there are lots of places that people would like to visit. It’s not like they post libraries, or other government run facilities on freeways. Is there a policy that requires these types of facilities be displayed on the freeway exit sign? I tried to google it without finding the answer I was looking for.
