Utah Oversize Permit Cost: Worked Examples

Utah prices oversize permits in three currencies. A load that breaks only a dimension limit buys a flat class fee. A heavy non-divisible load buys a flat fee inside a weight band. Past 125,000 pounds, the statute switches to arithmetic: a per-mile rate charged on every thousand pounds above 80,000, with three rounding rules that decide the final bill. The three moves below run each math the way UDOT's Motor Carrier Division does.

Example 1: the width-only move and its 96 hours

A precast wall panel leaves a Salt Lake City yard for a site in St. George, loaded 12 feet 6 inches wide and 13 feet 6 inches high on a step deck. The gross weight stays at or under the 80,000 pound legal maximum of Utah Code 72-7-404(4), and the height stays under the 14 foot limit of 72-7-402(5). Width is the only limit exceeded: past the 8 feet 6 inch legal width of 72-7-402(4), the move needs the oversize permit of 72-7-406(5).

The fee line is one number. A single trip oversize permit costs $30 under 72-7-406(5)(a)(iii), and it is valid for not more than 96 continuous hours. The clock does not care whether the truck moves: bought Monday at 8 a.m., the permit expires Friday at 8 a.m. Utah sells the same class as a $75 semiannual and a $90 annual, and the annual covers dimensions up to 14 feet 6 inches wide, 14 feet 6 inches high, and 105 feet long under R909-2-16(1)(b). A weekly move at this width matches the annual's price on its third run.

Two timing rules matter more than the fee. At more than 12 feet wide, the load falls under the R909-2-12 commuter curfew: no travel Monday through Friday between 6 and 9 a.m. and between 3:30 and 6 p.m. Mountain time on the Wasatch Front segments the rule lists, meaning the highways of Weber, Davis, and Salt Lake Counties; Utah County north of I-15 Exit 261; I-80 across the Salt Lake Valley; I-84 west of milepost 94; SR 68 north of milepost 16; and the highways south of the Perry Willard interchange. A Friday 4 p.m. departure out of Salt Lake County is the wrong plan; a 9:15 a.m. start runs the state southbound before the afternoon window opens.

Escorts cost more than the permit. In daylight on a freeway, Table 3 of R909-2-14 first requires a pilot car above 14 feet of width, 120 feet of length, or 20 feet of overhang, so this load runs I-15 alone. After dark, the same table requires one escort for anything between 12 and 14 feet wide on a freeway. The same $30 buys a cheaper trip if the wheels roll in daylight.

Example 2: the recurring overweight move and the band edges

A carrier based in Ogden moves a 105,000 pound non-divisible press to job sites twice a month. The load is past the 80,000 pound legal gross but under 125,000 pounds, so every move buys an oversize and overweight single trip at $60 under 72-7-406(6)(b), each one valid 96 continuous hours.

Twenty-six singles in a year cost $1,560. The statute sells the same privilege in bulk: for a gross weight over 84,000 and up to 112,000 pounds, the semiannual permit is $320 and the annual is $480 under 72-7-406(6)(c) and (d). The breakevens are small whole numbers. The sixth single trip inside 180 days outspends the semiannual. The ninth single trip of the year outspends the annual. The twice-a-month carrier pays $480 instead of $1,560, a $1,080 difference for buying a different term.

The band edges deserve a read before checkout. The $320 and $480 figures hold only up to 112,000 pounds; a re-rated load at 115,000 pounds lands in the top band, $420 semiannual and $540 annual. Below 84,000 pounds the same terms cost $180 and $240. No fee buys out the registration prerequisite of 72-7-406(4): the vehicle must be registered for the weight the permit authorizes, or for a gross laden weight of 78,001 pounds or more, before any permit past 80,000 pounds is valid at all.

Example 3: the superload formula, worked to the dollar

A 190,000 pound transformer comes off a rail ramp in Salt Lake City with a routed distance of 145 miles. Past 125,000 pounds, 72-7-406(7) allows a single trip permit only, and the fee stops being flat. Here is the statute's arithmetic, step by step:

• The gross weight rounds up to the next 25,000 pound increment under 72-7-406(7)(c)(ii): 190,000 pounds becomes 200,000.
• The billable weight is every 1,000 pounds above 80,000 under 72-7-406(7)(b): 120 units.
• The miles round up to the next 50 mile increment under 72-7-406(7)(c)(i): 145 becomes 150.
• The rate runs $0.012 per mile per unit: 0.012 x 120 x 150 = $216.
• The dollar amount rounds to the nearest $10 under 72-7-406(7)(c)(iii): $216 becomes $220.

UDOT publishes the same matrix as a table on its fee schedule page, and the 200,000 pound row meets the 150 mile column at $220. The rounding is the point: the load pays for weight and miles it never actually ran.

The bounds bite at both ends. A 130,000 pound load over 50 miles computes to $42, and the $80 minimum of 72-7-406(7)(b) lifts the bill. A 250,000 pound load over 300 miles computes to $612, and the $540 maximum cuts it back down. One more cost sits in the calendar: UDOT processes loads over 17 feet 6 inches high, over 17 feet wide, or over 300,000 pounds only during business hours, and approval can take up to 14 days.

What a pilot car adds in Utah

Utah's escort table runs on two axes, freeway or non-freeway and daylight or dark, with daylight defined as half an hour before sunrise to half an hour after sunset under R909-2-3(8). The carrier follows the most stringent cell that applies, R909-2-14(1)(b). In daylight on a freeway, the first escort arrives above 14 feet of width, 120 feet of length, or 20 feet of overhang; on a non-freeway, above 12 feet of width or 105 feet of length. After dark, one escort covers a 12 to 14 foot width on a freeway, while anything over 14 feet wide, 105 feet long, 14 feet 6 inches high, or 10 feet of overhang may not move at night at all. Above 16 feet wide or high the count reaches two. Above 20 feet wide, 175 feet long, or 17 feet 6 inches high, the load takes two pilot escorts plus at least two police escorts, with the Utah Highway Patrol setting the count.

The escort is a specified vehicle, spelled out in R909-2-24: a passenger car or two axle truck with a 95 inch minimum wheelbase, a 12,000 pound maximum, no trailer in tow, a roof mounted OVERSIZE LOAD sign at least 5 feet by 10 inches, amber lights visible around the vehicle, and a two way radio with a half mile range. The escort driver carries at least $750,000 in combined single limit coverage under R909-2-24(9). One escort changes a job's cost; two plus police changes its schedule.

The buying rules that outrank the math

Three rules decide more than any fee cell does. Permits are bought before operating in Utah, online through UDOT's Motor Carrier Services system with a credit card, and the exception list in R909-2-8(1) has exactly three entries: northbound I-15 at the St. George port of entry, westbound I-80 at Echo, and eastbound I-80 at Wendover. The permit rides in the vehicle, and an electronic copy on a phone satisfies 72-7-406(3). All sales are final, so the rounding in Example 3 is worth re-running before checkout rather than after.

The fee line on a Utah oversize move runs $30 to $540. The schedule around it, curfews, escorts, band edges, and a 14 day review on the biggest loads, is where the money and the calendar actually go.
