Decided to not be so lazy, and pulled the post I referenced from that other place:
If you are a nanny, please stop reading now! Further reading may cause apoplexy, discombulation and/or heart failure.
As the low traction time of year is once again upon us; it's time for Winter Stunt Driving 101.
1. Find a nice snow or ice covered open space.
2. unplug the electric cord from your empty trailer (can't have that pesky ABS ruining our fun!)
3. Engage your diff lock.
4. approach right side of area at ~1300 rpm in your lowest high-side gear, constant throttle.
5. as you start a shallow left turn, grab a handful of johnny bar and hold it.
6. trailer will swing rapidly to the right, when it gets to at least 45 degrees, stomp (throttle) and steer (left)
7. the tractor trailer unit will rotate nicely about a point near your posterior.
8. as your trailer's momentum bleeds off, it will gradually start to straighten relative to your tractor.
9. release the trailer brakes, and once rotation stops, you can ease off the throttle.
10. smile, repeat, enjoy!
Now that I've stirred the pot a little, the philosophy behind this: If you don't know what your rig feels like when it's out of control, when it happens accidentally, you're going to be in deep &*%#. And I wouldn't recommend this as your first experiment, but you do need to know how a big slide feels, and what works to get you out of it. Contrary to your Safety Directors opinion, slowing down is not always the answer. Cutting power at step 6 above will do a very nice job of introducing your truck and trailer! Horsepower can be your best friend in the right spot.
Go play in an empty lot, and soon you'll feel your trailer start to slide without having to see that it's sliding. Same for the drives. Each axle will feel different to your backside because the physics of each type of slide varies.
Don't get crazy, but stomp on the brakes in a slick lot. see how it feels. It's a lot better to be a little freaked out at 5 mph than totally spazzed at 35 or 40. You can leave all the space in the world, sooner or later some idiot will cause you to have to do an emergency stop in some real nasty spot. And even with ABS, your truck and trailer are gonna be moving around in ways you may have never felt before as they fight for traction. And you should know what's happening by feel so you can concentrate on the moron whose trying to make you play Dr. Kevorkian.
Be safe out there, know your limits, and stop at 80%. Better to stop a little early than to fall off the far side of 100%.The fall won't hurt but the stop sure will!

Now if your feeling lucky steer away from trailer hit brakes then drive backwards rest of the trip.But keep that rabbit foot handy.BTW if a rabbits foot is so lucky how did the rabbit lose it
-
The only thing that ever worked for me in such circumstances was to let off the throttle and coast in gear. But then again, I never did like driving on ice.
-
I can say with some authority that feeling the ###-end of my rig go in a direction not intended by the engineers and design flunkies is.. not pleasant. And for me, it was only about 15 feet sideways.
If a loaded trailer wants to go sideways, the tractor WILL follow - until something big and massive stops it -
What do you do when your going up a hill, have to stop, and start sliding down backwards?
-
Pop the brakes and abandon ship!
LOL... seriously though, I had that fear one time when I got stopped behind another truck who couldn't make it up Vail. I thought for sure I was gonna go sliding back down the hilldidn't happen. We sat there for a few hours til the sand trucks came by.
And Lurch: I know EXACTLY what it feels like to lose total control of the rig... albeit bobtail though.
I was driving a Freightshaker COE with the setback axle (we called 'em a bus, because that's what they looked like). There was a very light snow on the groundjust a dusting. I let off the throttle to shift while going about 20 mph and the tractor did a complete 180 with ZERO warning.
I never bobtailed that truck on anything other than dry roads after that! -
I dunno, but I had a friend who had an interesting experience. He was going down one of the Rockies grades, smoked the brakes, lost all braking capacity and was a runaway truck - I remember it was as 7% grade. However he did it, he managed to keep the truck on the highway until it started going up the other side. This was before engine brakes - he used the engine as much as possible to slow the thing down. There was a pullout at some point where he had the truck slowed down enough to pull off the road and it finally - sort of - came to a stop.
Then it started rolling backwards - brakes were fried. He jumped out of the truck as soon as he felt the backwards motion and grabbed whatever he grabbed to throw behind the wheels to keep it from moving and further.
Going through something like is a lesson in what not to do in navigating mountain grades you probably will never forget : ) -
If you're going up a slick hill and think you're gonna have to stop, get out of those slick wheel tracks! You shouldn't be driving in an icy wheel track anyway, but for dang sure don't stop in 'em. Get half a lane over into the marbles, there's more traction there even on a very slick road. The heat & pressure of passing tires act like a very inefficient Zamboni!
-
Something "big and massive"?
Hmmmmmmm
How tall did you say you are?

If you get into the sliding down hill backwards scenario you have to recognize that you are truly and sincerely f###ed and pick a spot to crash. Honestly, there are some times when you just have to find the softest looking concrete and tuck into it.
Many years ago I watched a guy do just that down hill slide routine on The Sisters in WY. When we asked him about it he claimed that he tried to back up into the guard rail just so there was something that wasn't moving out there. It worked, more or less, and he ended up facing down hill with his cab in the front of the line and used the guard rail as a brake assist. Like the old saying goes, "if your falling, dive".
