“Boulder police are investigating the traffic signs as criminal tampering.”
“I appreciate the fact that it’s drawing attention to the fact that we’d like people to slow down and not be on their phones, but there’s probably, again, a few more appropriate ways about getting that message out.”
I’d love if they implemented whatever appropriate ways they have… then again they said appropriate, not effective.
There is probably some legality involved. Signs have more than informative meaning, where not pursuing this officially has broader ramifications.
Just the unauthorized visual distraction factor can be used as a means of argument in court until the matter has precedent in case law established.
