The slipprier it is, the less you can use engine braking. If you have ice on the road and no sand or salt, the closer you get to 32 degrees the less traction you have. I have had glare ice conditions with a tractor trailer where I had to shift into neutral to avoid locking my drive wheel and taking me off the road. Obviously, you can’t do that on a curvy downhill.
At 25 below ice has pretty good traction
We didn’t have ABS on tractor trailers, there was a Federal mandate to require it in the late 70s when the Feds required the states to raise the weight limits on the interstates from 72000 lb to 80000 lb but it was such a disaster that it was soon discontinued. You have not known real excitement until you have taken a loaded tractor trailer through a toll booth at 60 mph because it wouldn’t even slow up while tha ABS was going psst,psst,psst.
Bank alarms, and many other electronic devices used to make them act up.
