Okay could use some tips on winter driving.I haul with grain tailer and thats pretty light so how do you keep from tailer locking up or what should a guy do to keep from jacknifing.Would this be a good time for jake breaking?

When the roads are icy, it's always a challenge to keep your trailer "strait" behind you when empty if your braking "too" hard for conditions...

The simple answer is to drive "ahead" of yourself, anticipate traffic slow downs, and traffic lights etc. This is why your paid the "big" money...

Watch for "stale" green lights, watch for "don't walk" lights on your "lane" of travel, sometimes, I know, 7 flashes of "don't walk" = yellow light...

You will learn how to anticipate a "Slow down" OR CRASH :wink:

Your Question about Jake Braking and "JackKnifing" ....

Jackknifing is a very Rare thing in the north... ????

We drive on icy roads and don't "jackknife" Hmm...

I would strongly suggest, those who do "Jackknife" are relying on their Jake rather than slowing up the unit as a "whole" unit.....By using the brakes...

OR THE BRAKES ON THE TRAILER ARE COMPLETELY OUT OF AJUSTMENT !

Hopefully we all have the same thoughts here.

If you know the weather is bad or gonna be bad.

Step 1. I know you have heard it.

SLOW DOWN!!!!!!

If the roads are real bad, park it!!!

But if you must.

Slow down

Stay back.....Dont tailgate, increase your following distance

Expect the expected..... People are gonna do dumb things, watch out for it.

Plan your trip.... If you know the weather is gonna be bad 1,000 miles ahead, well plan on leaving early to compensate your time if possible

Know whats happening!!!! Constantly scan and scan more of whats going on around you. People drive like morons, Whats going on ahead of you 20 seconds, if you can see. Is that light red? Is there some guy turning ahead. Salt trucks. Get the big picture!!

If you should get close to a circumstance, make sure you leave yourself an out also. Are there cars next to you, behind you, in front of you??? If so, what if that car loses control on the side of you. Well, if you know some basic rules you will not be next to that guy when he spins out and you have options now. What if your traveling next to that guy when he spins out. Uh oh you have an accident. You get what I mean.

Turn off the Jake brake also!!!!!!!!!! Dont need it

Well I hope that helps. I have lots more advice but I will let some others chime in here as well.

I would also suggest some one give advice on mountain driving.

One final thought. Mods, you should post a sticky on here about winter driving, May help some of the new guys questions.

Maybe refer to some Smith training or something like that.

I haven't driven much in winter and any advice is good.The first time I drove on slick roads,I wasn't far from home,coming to stop sign a little faster than I should have,hit the brakes not real hard,looked in the mirrir and saw the trailer trying to come around.So, no one at intersection,no cars coming,shifted down one and went right around the corner.Now I drive like said here,anticipating farther ahead and if road there might not be healthy and drive accordingly.I do start braking way ahesd now and speed is way reduced.I just need any other good advice to keep it on the road.I already know that if its bad, its a no go.Thats hard to do when you own your own rig and got to make the payments.I just figure have to pick up a extra load for few extra days when its good to take up the slack.

It might sound a bit extreme :evil: but I was told in snow treat pretend thier are eggs on your gas and brake pedals and you dont want to break them!!

Also when coming off of the highway to exit ramps(especially cloverleaf exit ramps) BE CAREFULL. The salt trucks make the highways priority and the ramps come second. You might be doing fine going 50mph on the high way then you take an exit ramp and off you go :sad:

Slow down before a corner but don't ever just let off the pedal all the way or the drives could lock up. Accelerate into the corner just keeping enough power to the wheels to maintain speed.

Slow down before the crest of a hill until you get a look down the other side. This is the time most people panic when they see an accident on the other side so it's a good place for a pileup.

If the pavement is dry try to keep one set of wheels in it. If it's icy and the rest of the road covered in snow, keep your wheels in the snow so you have something to bite on.

When your first starting out in snow and your not moving fast enough, don't mash on the pedal, ease off and treat it like an egg shell. Mashing on the pedal and spinning your tires will create an ice rink.

Driving in snow is a talent you have to acquire and be able to feel. It comes with time and experience and not something you can learn over night.

I only drive tractor-trailers part time, so, my winter driving experience with them is somewhat limited. I spend most of my time in an ambulance and winter driving with those is no problem now that I have several years of experience. I'm noticing more and more that, like the ambulance, operating tractor-trailers on snowy roads is getting easier with experience but I'm still TERRIFIED going down bigger hills. There's a few big hills here that I run frequently and when they're slippery I can feel the back-ache before I even start going down the hill. I just find it really difficult to believe that most of the time, that big white box behind you will follow you without any problems!! And they also have brakes!! Haha! Anyway... any tips??

Your Question about Jake Braking and "JackKnifing" ....

Jackknifing is a very Rare thing in the north... ????

The farther south you go, the more common it seems to be. Using a Jake on bad roads can certainly contribute to a jackknife, but going too heavy on the throttle can do the same thing. Especially, if they have the diffentials locked. If all four sets of drives break loose, the tractor goes into a "tail-spin" because of being on the side of the "CROWN" of the road. Gravity pulls the "loose" wheels to the side and in about one second, it's too late to recover. If you "FEATHER the throttle, just enough to maintain momentum, you stand much less chance of breaking the drives loose. Also choose a higher gear to reduce the torque on the drives. If you do not have the differentials locked, chances are that only one drive will break loose, the rest act like a rudder to keep you in line, and you have time to release and re-apply a little less throttle.

We drive on icy roads and don't "jackknife" Hmm...

Or, they are relying on the differentials being locked ("4-WHEEL DRIVE SYNDROME") to give them enough traction to drive like they are on a dry road, and apply far too much throttle.

Doing 35 or 40 at the bottom of a hill, and 10 at the top gets you over the hill. Doing 20 at the bottom and coming to a stop half way up gets you into very serious trouble.

[Windwalker]

P.S.
Differential locks are a very good advantage when you are in a lot, trying to get started. Below 5 mph, they can be your best friends. But, once you get out on the pavement (ice or snow covered) and get over 5 mph, they can become one of your worst enemies. Between 5 and 10 mph, UNLOCK 'EM.

[Malaki86]

Even at slow speeds, coming to a stop can be dangerous.

I almost had a slow-motion jackknife while doing maybe 5mph. I was on a steep hill that was nothing but packed snow/ice. I managed to get stopped, but it was a long, slow experience.
