Utah has raised the speed limit on some highways to 80 mph, and Will Truman was there to check them out:
The signs all let us know that it’s experimental. They’re also heavily enforced. I’m not sure if that’s because of concern that drivers will take that as a license to go over 100 or because drivers already have. The end result is that on the way back, when the speed limit was 75 I drove 80 and when the speed limit was 80 I drove 80. Still, it’s a start.
In my circuit of (some of) Texas in 2008, I encountered a few stretches where the speed limit was 80; the Highway Patrol was very much in evidence, and traffic generally kept to 80 or slightly above, though I didn’t see any sudden brake lights in front of me when the limit dropped to 75 or lower.
On the other hand, on old US 90 west of Marfa, which was mostly deserted the day I drove it well, never mind. No sense in self-incrimination, after all. And by now, Texans are contemplating life at 85.
