That best thing to do is not put yourself in that sort of predicament. Reminds of my first and only jacknife situation, I was pulling into an ice covered parking lot in western Mass, looking to get some rest after making my delivery, as soon as my truck hit that slick surface, instant jacknife, no thoughts, nothing luckily I was moving slow and the trailer lodged against the headache rack, no damage, unless you count my ego(they're was already about 20 trucks parked, took a lot of razzing on the CB). I can still remember backing in circles trying to get out of it. To this day I am super cautious as to where I put any vehicle and when it comes to Ice, the answer is NO. Lesson well learned. I answered another post awhile back, when I was a kid driving a coal truck we always had a bucket of coal ashes in case we got stuck on a delivery, best traction action ever, good luck finding them nowadays.
If you're just parked on a slick spot you can kick in your power divider and your lockers and rock it back and forth and try to get going that way. If that don't work and you're on the side of a road there is always a little bit of gravel right off the shoulder even under the snow. If you have someone with you, you can get them to throw a chain underneath one of your drive tires as you're pulling forward. I would never recommend putting the truck in double under getting out in throwing the chain under a drive tire yourself that wouldn't be safe . Sometimes you just have to put a couple chains on or call somebody if nothing else works. In Alaska I carry a couple gallons traction gravel in a sealed bucket on my catwalk and a bottle jack that makes chaining up a breeze.
What I've heard about socks vs chains is socks are effective in dry powdery snow and not effective in wet snow.or slush. I also hear they are not durable. I've never used them.
Ice Melt or any potassium chloride ( I think that’s what it is) sold in a big jug, works great on ice. Sprinkled in front of tires and on top of Drives in tread, I carried it for years. Saved me once, When stuck on ice.
I always have a Rubbermaid tote on the floor of my passenger side that is 1 bag rock salt and 1 bag rocks/sand type stuff from Home Depot. Between this and a shovel I never got stuck and used to do 13 stops a night in rural Maine.
My company loans these types of "cheater chains" to our drivers in the winter months for helping to get out of situations. They seem to be pretty handy at times if you use them properly... 6085V Emergency Chains Heavy Truck 19.5-24.5 Rims ( 1 Pair)
If you have a manual truck, rock the truck back and forth. The little momentum can work wonders. All the times I have gotten stuck, I have used this technique. Also, do NOT spin the tires. This makes it worse. You don’t want to dig into the mud/snow/ice. If it’s hard snow, grab some dry dirt and throw it all over the tire and on the ground. Carrying some salt can also help. If it’s mud or snow, try clearing it a bit, but be careful as the equipment can slide and crush you. A small foldable shovel can help. I carry one in my truck during winter. The other possibility can be to throw in an object under the tires. It can be a wheel chock, wood, pieces of tire, or anything of that sort. I actually helped someone with a wheel chock who was stuck in a deep dirt hole. Tire socks are now legal in all 48 states and most, if not all, Canada. I’ve heard they are sensitive to dry pavement. They’re more adequate for roads fully covered with snow/ice. Chains are half as cheap, sturdier, and probably last longer. I do carry two pairs of socks in my truck, and two pairs of chains. I have never used neither (yet). I used to work for a company that did not allow their fleet to chain, except their chain gang.
Gotta say if you've never been stuck lucky you but it's coming.. Company gave us bags of poultry grit to stick under tires, gotta say used it twice this week and was surprised how well it worked. I was stuck here on soft snow.
