ISTR (it’s been 28 years since driver’s ed) that on Texas highways, including interstates, the minimum speed limit is 15 MPH under the posted maximum speed limit. So if the max is 75 mph, the min is 60 mph.
In the northeast part, yes. There is even, and I’m not making this up, *a runaway truck ramp!*LOL

In South Dakota, the minimum is 40 MPH. You’ll see it occasionally on a little sign attached to a speed limit sign but not on all speed limit signs.
They had them in Illinois. Many of times I was stopped in traffic right next to the “Minimum Speed 45 mph” sign.
IN CA, the law in mostly enforced if you’re driving crazy slow outside the "slow’ lane, and traffic is zooming past on both sides. Or if many vehicles are backed up behind you and you dont take turnouts.
So, to put it another way, if the posted limit is 55 on a country highway, and there’s a radar speed trap: If you’re going too fast they will tag you, despite traffic. If you’re going too slow they will only tag you if you have become a hazard.
Yes! Relatively flat compared to most states, but the closer u get to Wisconsin and the Mississippi river it gets pretty drastic. Enough to pop my ears a few times!
