Washington Winter Mountain Pass Chain Requirements

As we are heading into winter here I thought I would check up on the requirements for tacking my camper over the passes in winter. Because I have a 4x4 with M&S tires I figured that I wouldn't have to worry about chains. Was I in for a surprise. The rules are completely different for vehicles over 10,000 lb GVW. If I am reading this right the law requires, for vehicles over 10,000 lb's:

- chains on vehicles, both drive axel, if the signs say traction tires required or chains required.

- carrying a minimum of two extra sets off chains.

- carrying the 2 sets of chains regardless of road conditions from Nov. 1st to April 1st regardless of road conditions if I go over a pass.

Chain requirement law

Is this peoples actual experience?

So in the winter, I carry chain chains for the truck and cable chains for the trailer. Have had to use them a couple times and was glad I did. Without a trailer, then the weight limit would apply. If below that weight limit, then snow tires and/or 4x4 would be sufficient.

    I doubt very many people carry extra sets of chains. Though sometimes I do when winter snow camping as chains on both rear and front four wheels of a 4x4 can really pull.

    Same here. The carry requirement applies from about November 1 - April 1 (don't keep track of the exact dates, as I put them in plenty early)

    Chains on TT braking wheels. not any wheels unless all wheels are braking wheels.
  • WA chain law also pertains to MHs pulling toads. If the toad has auxilary braking then it must be chained.
    I have been asked to see if I had chains but never asked to show.
    In OR, I was going over the Siskiyous and OR State Police was checking everyone. I beleive this was more to space out traffic then actual chain inspection.
    It is best to wait out the traction devices requirement for cars and chains for over 10,000. When the truckers go with no chains, we go!
  • My 4x4 truck is stickered for 9800 lbs GVW and I carry one set of chains I can use on the front or rear drive axle on the 19.5's. When hauling the trailer, I avoid the passes in the winter but will carry a set of cable chains for it Nov-Apr just in case.
  • Washington will have State Patrol enforcing chain requirements on really bad days.
