In 2024 I was running I-70 Mountains in Colorado. I'd always see doubles trailers and fuel tankers fly by me in the mountains on snowy nights...no chains even though chains were required by electronic road signs.
So, 2 questions: why is it common that doubles and fuel tankers are flying fast in snowy conditions and why aren't they putting chains on when DOT required? I mean...only 4 drive tires are required to be chained...
Doubles/Tankers in snow and no chains?

If they run the mountains all the time there’s a good chance they had auto chains or sanders on their truck. Was your window down? Could hear for a fact that they didn’t have chains? Did you see if they had sanders in front of their drives?

This truck has sanders built into the storage boxes in front of the drives, you can see the tubes hanging down below the box. So a truck like this could appear to be running without traction devices when they in fact are equipped with them.
-
I did not know standard daycabs would have either of those. It's my understanding that when the electronic signs post the requirement 4 drive tires must have chains or ATDs affixed to tires. Idk
-
Flat out, they're probably just a better driver than you in those conditions, and know the conditions on that road better than the signs.
Yeah, I know it's the law, but chain up signs on don't always mean the conditions warrant it. But, you have to factor in the lowest denominator, who was likely you at that time.Toomanybikes, blairandgretchen, beastr123 and 8 others Thank this. -
Auto chains and sanders are a traction device just like regular chains. And if it’s a daycab that runs the area daily you could almost bet on them running those over conventional chains.

There was that one XPO or Saia doubles spinning out with chains on once I saw...guess that was the lowest denominator then.

Sorry I hurt your feelings.
He was probably light or empty. Chains can't grab much without weight. -
Or they were empty or super light. Especially with a single screw... If ur getting passed by doubles and tankers and local trucks, they are more used to what they are driving in, than you are. And have more expierence.. i used to run the northwest exclusively and there was always someone on the cb telling me im driving way to fast when the road was perfrctly fine to drive close to the speed limit.. probably the same guys that when the chain laws go up they park and tell everybody how dangerous it is to chain when im on my 8th chain up job of the day. when the road would turn to #### id be driving a safe speed to deal with it . Seems alot of guys dont know how to read the road and understand what they are driving on. Which is perfectly fine for newer drivers. It takes awhile to develop a feel and an understanding of what ur looking at. But dont get on the cb and yell at dudes who do this #### everyday and the current storm is another tuesday for them.Toomanybikes, Cdemars316, AModelCat and 8 others Thank this.
