Starting September 1, 2018, drivers will be required to start carrying a set of chains in the truck. In order to comply with varying State and Provincial regulations, drivers will be required to keep chains in the truck until May 31, 2019.

Len Dubois Trucking’s Chain Up Policy

As a general rule, Len Dubois Trucking’s safety policy states that if chain up warnings go into effect, it is unsafe to drive. The safety of our drivers is the top priority, so we prefer that you find a safe place to park and wait for the road conditions to clear up instead of chaining up.

How to Avoid Getting Stuck in the Middle of a Chain Up Warning

The Mountain States all have potentially dangerous winter driving conditions and chain up warning can go into effect at any time. While there is no guarantee that you won’t get caught out in Chain Up conditions, checking the weather and road conditions beforehand can certainly help you avoid these dangerous conditions.

We’ve compiled a list of the most common Chain Up areas where we regularly travel. Before you head out, and during your approach to these areas, make sure that you stay on top of the weather and road conditions.

Full Chain Up

Every mountain state and province has their own chain requirements. A general rule of thumb is that a full chain up involves chaining up:

  • All four tires on front drive axle
  • Outside tires of rear drive axle
  • One tire on each side of the trailer
