Talk:902.5 Traffic Control Signal Features (MUTCD Chapter 4D)
902.5.17 in reference to retroreflective backplates for signalized intersection. I notice that we have to different breakouts speaking about the retroreflective backplates. This is fine but we spell out two different speeds (mph) that the retroreflective backplates should be installed on. 55mph and 45mph - according to MUTCD, they mention that the retroreflective backplates should be installed on 45mph travelways. Please let me know what you think? Thank you for your time and consideration,
