Title: Green Reflectors in Colorado
Post by: Brian556 on January 19, 2018, 01:00:36 AM
In this GSV, there are triple green reflectors marking the end of the guardrail. When I was in CO in 1992, I saw individual green reflectors at what seemed like random locations, generally behind guardrails, but never triples. Is this just an error, or standard practice? What is the reason for using green reflectors?

Not sure in this particular case. It could just signify the endpoints of the guardrail (the tall posts seen here might be potentially helpful in locating rails during snow removal operations). Some states use reflectors like this to indicate to road maintenance crews where drainage locations are (Nevada uses blue for this).

Deliniators and reflectors?

These aren't reflectors in the sense used in MUTCD Chapter 3A, as those refer to reflectors used as pavement markings while this thread is about reflectors used on a post. And these are not delineators as described in Chapter 3F, since they are only used at certain points (delineators would be placed at constant intervals along the highway). Green is not an approved color for either use.

Green. Colorado.

Someone had to say it.
