I have a problem with the construction workers routing traffic. They (at least in NH) hold up a sign that displays either “slow” or “stop”.
The problem is that the colors and sizes are the same for the two, and the words are similar, so that it’s easy to be unsure of which one is displayed.
What made it worse for me today, as I was slowing down approaching the worker (my lane was blocked), unsure of the sign, the pickup truck behind me pulled out over the double line and started to pass me. I had to signal him frantically (at that point I had determined the sign was “slow”) so I could pull out.
Bottom line, the signs could be and should be much easier to distinguish. Just a different color would help. Red for the “stop” and yellow for the “slow”, for example.
