But quick question about a resource. I’m looking for a current, printable one-pager that lists CMV chain requirements and activation rules by state (dates, corridors, trigger codes) for CO, UT, WY, ID, OR, and WA — for example, Colorado’s I‑70 carry requirement from Sep 1 to May 31 between MM 133–259. What are you using that stays accurate and is easy to hand to dispatch and drivers when DOT starts enforcing hard during storms?
I keep a one-pager in Google Sheets built from each DOT’s chain page, then reprint monthly; it lists dates, corridors, and the state “codes,” plus a QR to day-of activation pages like CO’s: https://www.codot.gov/travel/winter-driving/chain-laws. Not pretty, but it beats juggling six tabs at 5 a.m.; only caveat is we still pencil in local oddities (e.g., WY Level 1/2 notes) — want a copy?
I quit chasing blog roundups and grabbed J. J. Keller’s laminated tire chain laws card, then pencil in our lanes — CO I‑70 MM 133–259 Sep 1–May 31 and WY “Level 1/2” notes — so it fits on one page for dispatch.
Quick example: I use a one-page PDF that Zapier refreshes every Monday from the six DOT pages, with a big “Valid thru” date and a retargetable QR (bit.ly) so if a state shifts its activation page we don’t reprint — CO live ref: COtrip Traveler Information Homepage; I still do a pre-storm spot check for OR/WA corridors.
