Why the heck does Colorado love to put them at the end of off ramps?? That makes for some tight maneuvering. Hate them!!
Yeah, they've been putting them in on the off ramps from I-70 in the high country for a few years now. I've gotten used to the one at Gypsum (exit 140) but I hate the one on Main Street at Silt (exit 97) because it's so dang tight. Getting to some of the rest areas up there is an adventure as well, and the roundabouts don't help.

Did you see the video? If you notice, the central circle has a wide, usually red, apron to allow the rear tandems a place to go.
Yeah, there's still a bit of confusion about what to do. But the rule is to take it slow. I like them because there's no red light, no timing a left turn between oncoming cars, even the right turns have an easy path.
Tandems:
Tandem Axles
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".
