A roundabout is a right into it and a right out of it (with few exceptions).
The green is kinda down to history (and not used everywhere) from when WWII ended and we had a shitton of green paint and a shitton of white paint, all government surplus. Government surplus meant the different departments (or states, or anyone really) could get a bunch of it for very little money. So, they used green paint and white letters. The green was a very different green back then.
Today, it's a very special paint that makes the light reflect in very specific ways. Seriously, it's like $400 for a gallon of the paint and only a couple of companies manufacture it. The green will be dark at certain angles and show the white lettering more clearly.
They tried changing the font but it has been restored for the national highway system. States and cities/towns may have their own standards and colors. The two most used in the US are Highway Gothic and Clearview.
Yeah, that's what I was thinking, a roundabout is a way of making right turns to go to the left.
I suppose the paint tech has advanced greatly
The paint for the signs is outlandishly expensive. The paint for the lane markings is also insanely expensive.
They both have to be made to very exacting standards. They must reflect some light, but only so much light. They have to resist fade. They have to withstand harsh treatments. They have to expand and contract with the surfaces they cover. The list goes on...
So, there's a reason for it to be so expensive. Well, that and only one or two companies make it. I think it may only be just one company that makes the sign paint and a couple that make the paint for lane markings.
Is there someone with the job of testing the reflectivity of road signs?
