Winter Speeds when the weather is bad?

Assuming a consistent rate of speed both up and down, I'm going to guess 45mph.

15mph up. 15+15 for 30 + another 15 to make up for the 15 less up.

 

45mph is not the answer, that would be far too easy.
thanks for trying.

 

I'm never in that much of a hurry that I feel I have to push hard in slick conditions, I just run in the right lane, usually at 50 mph. If the truck ahead of me is doing 45 then I'm fine with that.

Freezing rain is a different story, I'll just park and wait and don't care if the dog food is late or not.

I can't count how many times I've been in the right lane just to have trucks blowing past me on the left and then 20 miles later to see one of them wrecked in the ditch.

I don't need that, in fact, I'm not worried about losing control myself as I am about getting caught up in someone else's mistake.

If I make a hundred bucks less that day/week because I stopped and waited it out then BFD...

 

Simply put, there is not enough time to accomplish the task in the distance given.
The ? is valid it just requires thinking outside of the box to solve.
So does driving a truck sometimes it works ,sometimes it doesn't.

Now apply that to the water under the tires, at a faster speed there is not enough time for water to form under the tires so more traction at speed, up to a point. Also that is why you get more traction in colder temperature.

In theory at least but I don't recommend any body testing the theory. You are on your own and make sure there is nobody else around.

 

Last year there was a stretch from Clearwater to Valemount in BC that was glare ice underneath a wet looking surface. 30km/h was even too fast. No rule of thumb, just drive to the conditions.

 

I go with the flow of traffic. If it's 3 am then I'll do the speed limit as long as the snow doesn't build up too high
