What NOT to do when crossing an ice covered bridge

If it is OK to run with the power divider locked in this age of enlightenment, why is there an on and off switch?

 

Yeah, I didn't even see his steers point in a sane direction even when the truck was well into the median. might aswell be asleep at the wheel

 

Because you.dont always need the diff lock engaged, and at slower speeds in slippery conditions it can actually cause the drives to push you straight when you try to turn......

 

Well I would never have thought such a thing.

 

I choose answer "C".......Stay off the roads.

 

In cold and wet temps. I pull on shoulder put on my ice cleats and safety vest then check the bridge for ice. Then after I proceed slowely with 4 ways on. That is the best approach

 

Call dispatch and let them know that if they don't hear back from you in 5 minutes there is trouble.

 

After reading through many of the replies, I can easily see why so many truckers screw up this time of year ... nobody knows the hell they're doing.

Power divider/inter-axle lock usage [or not using] had NOTHING to do with this or similar accidents.

A few hit the nail on the head. it was obvious the bride was icy as opposed to the road surface. All he had to do was coast across that short bridge. Hitting the non-iced pavement at the end of the bridge is what caused the tires to grab and send the truck into a irrecoverable situation once in a jack-knife attitude.

The bridge was at the top of an incline so power (torque] was no doubt [cluelessly] being applied while on the bridge. Ice and high[er] torque DO NOT mix, locked differential or not. Once the combination gets out of line, it's too late. Trick is to keep the combination in a straight line. It's really just that simple.

Power divider [and inter-axle locks] are ONLY going to be of meaningful help in snowy parking lots and going up steeper grades and getting the weight and momentum going on slicker roads. If you're thinking that is going to keep you out of trouble, I can see where you're going off the beam and why you will end up like so many others cross-ways in the grass.

 

It's a very short wheelbase tractor. Once they start to jacknife there usually ain't no recovery. His drive was sliding right as his steers came off the bridge and I would guess at that point he was braking. So trailer still on ice pushes forward and kicks out drive. Destination: ditch.

 

lmao the op must have gotten great training from someone who doesnt make money in the winter lol..

ice is ice you cant prepare for it but u can avoid crashing in it. i came down parleys summit in utah if anyone knows there is that bridge that actually is in mid turn i turned but the truck kept going straight until i hit snow again i shattered a little bit but survived to tell about it lol.

i actually look forward to every day driving over donner pass and lately ive been hoping for some more snow and rain ( i call it the donner party bunch of drivers running around chaining up) also p.s i do the same thing every day as a ltl driver from sacramento to reno/tahoe city areas
