Utah oversize permit rules
What Utah charges for a single-trip OS/OW permit, the limits that trigger one, and the escort thresholds — read from the state’s own publication. This rule has been in effect since 2026-03-16.
Oversize permit
$30
One price for a single-trip permit, whatever the dimensions. A 9-foot-wide load and a 16-foot-wide load pay the same.
Overweight permit
From $60
Scales with weight and axle count — there is no single figure.
A load that is both oversize and overweight pays this fee only, not both.
+ $20 Permigo service fee per permit, state fees at cost.
Legal limits
Exceed any one of these in Utah and you need a permit for this state.
| Limit | Interstate |
|---|---|
| Width | 8'6" |
| Height | 14'0" |
| Length | 65'0" |
| Gross weight | 80,000 lbs |
| Single axle | 20,000 lbs |
| Tandem axle | 34,000 lbs |
| Trailer length | 53'0" |
What the permit costs
Utah prices a single-trip permit as flat rate. One price for a single-trip permit, whatever the dimensions. A 9-foot-wide load and a 16-foot-wide load pay the same.
Escort requirements
Thresholds by road class. Where two classes differ, the road you are actually on governs.
Freeway (incl. SR-201 I-80→7200 W)
| Width | Requirement |
|---|---|
| Over 8'6" | 1 rear escort (night only)NIGHT (freeway): 12'–14' wide takes 1 pilot; over 14' wide, 105' long, 14'6" high, or 10' of overhang = NOT AUTHORIZED at night (Table 3). Tow trucks ≤120'/≤10' exempt ((1)(f)). |
| Over 10'0" | Marking requiredOver 10' wide: flags on extremities; weather gate — no movement with snow/ice accumulation or visibility under 1,000' (R909-2-11). |
| Over 14'0" | 1 rear escortOver 14' wide (freeway, daylight): 1 pilot escort (Table 3). The 2026 Table 3 specifies COUNTS only — no front/rear positions (except overhang: front pilot for front overhang, rear for rear, R909-2-14(1)(d)). Placement here follows pilot best practice (lead on 2-lane, follow on divided); 'a motor carrier shall follow the most stringent requirement that applies' and UDOT may require more ((1)(b),(e)). |
| Over 16'0" | 1 front escort + 1 rear escortOver 16' wide (freeway): 2 pilot escorts (Table 3). |
| Over 17'0" | superload permitOver 17' wide: the Super Load Team queue (UDOT verbatim: 'exceeds 17 feet in width or 17 feet 6 inches in height... placed in a permitting queue') — apply ≥2 business days ahead online; regional right-of-way clearance can take up to 14 days. Police per Table 3: 2 pilots + at least 2 police at >17' W on secondary / >20' W on freeways (count ultimately UHP's call, (1)(c)); UHP letter of understanding ≥48 h ([email protected]), permittee pays (rate unpublished). |
| Over 20'0" | 2 police escortsOver 20' wide on freeways: 2 pilots + at least 2 police escorts (Table 3). |
| Height | Requirement |
|---|---|
| Over 16'0" | 1 front escort + 1 rear escort · height poleOver 16' high: TWO pilot escorts on all roads (Table 3 — height jumps straight to 2, no 1-pilot step), and the height pole is EQUIPMENT on a pilot ('a height-measuring pole... only required if escorting a vehicle or load exceeding 16 feet in height', R909-2-24(7)(a)(ix)) — no separate pole car in Utah. Night: >14'6" high is not authorized. |
| Over 17'6" | 2 police escorts · superloadOver 17'6" high: superload queue + 2 pilots + at least 2 police escorts on all roads (Table 3); >19' may additionally require a route survey (UDOT discretion). |
| Over 19'0" | Conditions applyOver 19' high: a route survey MAY be required — UDOT case-by-case (verified UDOT page). |
| Length | Requirement |
|---|---|
| Over 105'0" | Travel window appliesOver 105' long: no night travel (Table 3 night cap); holiday/curfew trigger; signs required. |
| Over 120'0" | 1 rear escortOver 120' long (freeway, daylight): 1 pilot escort (Table 3). The 2026 Table 3 specifies COUNTS only — no front/rear positions (except overhang: front pilot for front overhang, rear for rear, R909-2-14(1)(d)). Placement here follows pilot best practice (lead on 2-lane, follow on divided); 'a motor carrier shall follow the most stringent requirement that applies' and UDOT may require more ((1)(b),(e)). |
| Over 175'0" | 1 front escort + 1 rear escort · 2 police escortsOver 175' long: 2 pilots + AT LEAST 2 police escorts (Table 3, eff. 3/16/2026 — the old '>175'=1 / >200'=2' step is gone from the rule; UDOT's page still prints it — rule governs,) |
| Front overhang | Requirement |
|---|---|
| Over 3'0" | Marking requiredFront overhang over 3' at night: steady amber marker light (R909-2-14(2)); legal front overhang 3' (72-7-402(5)(a), from the front of the body/power unit; 4' with stinger steer). |
| Over 10'0" | Travel window appliesOver 10' of overhang: no night travel (Table 3); weather gate; holiday/curfew triggers unaffected (width/length/height only). |
| Over 20'0" | 1 front escortOverhang greater than 20': one pilot escort positioned TO THE FRONT for front overhangs (R909-2-14(1)(d) verbatim); 500'-visible beacon ≥4' high at night. |

THE OLD >300,000 'SUPERLOAD' TRIGGER IS DEBUNKED — no weight-based superload exists in current statute, rule, or UDOT pages; the superload queue is width/height only (>17'W / >17'6"H). Axle-width bonuses: 9'-wide axles +7.5%, 10'-wide +15%, 8-tire axles +10% (R909-2-22(8)-(10)). |
