Those are the general Washington single-trip oversize/overweight permit rates. The total depends on the route. We do not calculate routes. We publish what the state publishes.

Official WSDOT types/fees page: “Single Trip OSOW - A single trip, 3-day, oversize and/or overweight route specific permit. This permit is for non-divisible loads only. Dimensional permits are $10.00 Weight permits vary, the minimum price is $14.00.”

RCW 46.44.0941: “All overlegal loads, except overweight, single trip. . . .$ 10.00” plus the overweight fee schedule per mile. “The minimum fee for any overweight permit shall be $14.00.”

Excess weight over legal capacityCost per mile
0–9,999 pounds$0.07
10,000–14,999$0.14
15,000–19,999$0.21
20,000–24,999$0.28
25,000–29,999$0.35
30,000–34,999$0.49
35,000–39,999$0.63
40,000–44,999$0.79
45,000–49,999$0.93
50,000–54,999$1.14
55,000–59,999$1.35
60,000–64,999$1.56
65,000–69,999$1.77
70,000–74,999$2.12
75,000–79,999$2.47
80,000–84,999$2.82
85,000–89,999$3.17
90,000–94,999$3.52
95,000–99,999$3.87
100,000 pounds$4.25

RCW: “The fee for weights in excess of 100,000 pounds is $4.25 plus 50 cents for each 5,000 pound increment or portion thereof exceeding 100,000 pounds.” Amounts under even dollars round as the statute prints (50 cents or over to the next full dollar).

Example, not a quote: 100 assumed miles at the printed $0.07 per mile on 0–9,999 excess pounds is $7.00; the printed $14.00 minimum applies, so that example is $14.00. The desk runs its own miles. We do not take origin or destination.
