Where the filing line sits, and why it is not where it looks
Washington’s insurance filing is set by WAC 480-14-250, filed July 13, 2023 under WSR 23-15-054, and it is keyed to the permit rather than to the safety chapter. The filing covers “each motor vehicle as defined in RCW 81.80.010 used or to be used under the permit”, which is why the permit question above has to be settled before this one can be.
The rule sets two tables on either side of a single weight line. For vehicles with gross vehicle weight ratings of 10,000 pounds or more, a non-hazardous property filing is $750,000. For vehicles with gross vehicle weight ratings less than 10,000 pounds, a non-hazardous property filing is $300,000. Hazardous categories run higher on both tables, to $1,000,000 and $5,000,000 depending on the material and the packaging.
Two details in that arrangement matter more than the headline figures. The first is that the line is at 10,000 pounds, not at 10,001 — it does not coincide with the bottom of the safety band, and a page that rounded them together would be describing a regime Washington does not have. The second is that there is no gap. A light truck below the line does not fall out of the filing requirement; it moves to the lower table. An operator who assumed the small end of the fleet carried no state filing obligation has assumed something the rule does not say.
For a combination, the practical question is which vehicle the filing attaches to, and the rule answers it per vehicle used under the permit rather than per combination. That is a different unit of account from the safety rule directly above, which speaks to the rating of the vehicle in the band. Two rules, two units, one truck — and the reconciliation is an operational fact about a particular fleet rather than something the text resolves in the abstract.
None of these figures is permanent and none of them shares a clock. The safety rule was last amended effective June 27, 2026. The filing rule was filed in July 2023. The permit statute was last amended in 2009. Any of the three can move without the others, and a change by expiry or repeal leaves no amendment notice to find — a lapse simply restores whatever it displaced.
