Normally covered/dark/blank signs

[vdeane]

Until recently this latter sign was lit up continuously during the current construction of the wildlife crossing overpass, but whenever I tuned into that station, I just got "This is a Caltrans test message" repeated.  Likely the radio message was only activated when lanes (or the entire freeway) were closed, but no one thought to change this sign's status.

Sounds like a good way to get people to ignore the sign.  Hasn't CalTrans heard of the boy who cried wolf?
