Arizona Oversize Permits and Route Restrictions
ADOT ePRO permits, Class A and Class C limits, Table 4 route escorts, metro curfews and certified escort operators
Quick answer
What permit class does an Arizona oversize load need?
Class A, if the load stays within 14 ft wide, 16 ft high, 120 ft long and 250,000 lb; a single trip costs $15 oversize or $75 overweight. Anything larger, or over a Table 4 route limit, needs a Class C permit from ADOT's Class C Unit. Both are ordered in ePRO, by mail, through a permit service or at a port of entry, never by phone.
Updated October 2026 by the HTS Logistics broker team (FMCSA MC# 1178470).
Checked October 2026; the issued permit controls
Arizona's permit rules live in two documents: 17 A.A.C. 6, the rule chapter in effect since July 8, 2022, and Table 4, ADOT's route-by-route list of escorts, bridge conditions and closures (master list as of July 10, 2025). Escorts come mostly from that table rather than a statewide width chart, so the same 13 ft wide load can run on I-10 with no width escort and need front and rear escorts on SR 87; the oversize permits by state hub shows how other states set theirs.
For heavy haul lanes through Arizona, HTS Logistics (broker MC 1178470) starts with the Table 4 entries for each route segment, then orders the ePRO permit, books the carrier and schedules the certified escorts and DPS officers those entries call for. ADOT permits cover only the State Highway System, so a jobsite on a city street, county road or tribal route also needs that government's permission (A.R.S. 28-1103; A.A.C. R17-6-105).
Legal limits in Arizona
Arizona's statute defaults sit below its working limits: A.R.S. 28-1093 starts at 8 ft wide and 28-1094 at 13 ft 6 in high, but 102 in and 14 ft are legal on the State Highway System and designated routes. ADOT's permit thresholds in A.A.C. R17-6-102 Table 1 are 8 ft 6 in and 14 ft, dropping to 8 ft and 13 ft 6 in where Table 4 restricts a route.
| Limit | Arizona | Federal baseline | Notes |
|---|---|---|---|
| Width | 8 ft 6 in | 8 ft 6 in (102 in) on the National Network | 102 in excluding safety equipment on Interstates, qualifying federal-aid and designated highways; the statute default is 8 ft (28-1093) |
| Height | 14 ft | No federal limit | State Highway System; 13 ft 6 in on roads not designated for 14 ft (28-1094); a $45 annual height permit covers up to 14 ft laden on designated routes |
| Semitrailer length | 57 ft 6 in | States must allow at least 48 ft | National Network; elsewhere 53 ft, or longer only if the whole combination is 65 ft or less; loads may extend 3 ft in front and 6 ft behind (28-1097) |
| Gross weight | 80,000 lb | 80,000 lb | 5 or more axles, under the federal bridge formula; natural gas, battery-electric or hydrogen vehicles up to 82,000 lb (28-1100) |
| Single axle | 20,000 lb | 20,000 lb | Including enforcement tolerances; motor homes and buses 24,000 lb (28-1099) |
| Tandem axle | 34,000 lb | 34,000 lb | Axles over 40 in to 96 in apart, including tolerances; legal weight is the lesser of these limits and the manufacturer's rating |
Federal baseline: 23 CFR Part 658, eCFR as of 2026-10-14
When Arizona requires a permit and how to get one
ADOT's Enforcement and Compliance Division issues Class A permits for specific non-reducible loads up to 14 ft wide, 16 ft high, 120 ft long and 250,000 lb, as a single trip (96 hours), a 30-day or an annual permit (R17-6-201). The power unit must be registered for 80,000 lb, Class A may not be used to routinely haul legal loads on over-width trailers, and a single trip may get one extension of up to four days for mechanical failure or bad weather (R17-6-106).
Class C is Arizona's superload category, though the rules never use the word. It covers a load over any Class A limit, over the R17-6-411 axle tables or a Table 4 route restriction, or projecting more than 2 ft (under 12 in thick) or 3 ft (12 in or thicker) from either side (R17-6-211, R17-6-307). The Class C Unit in Phoenix averages 48 hours to issue, not counting evenings, weekends and state holidays, and its permits are valid four working days on state and Interstate highways.

Fees
| Class A permit | Single trip | 30-day | Annual |
|---|---|---|---|
| Oversize only | $15 | $30 | $360 |
| Overweight, or oversize and overweight, up to 250,000 lb | $75 | $75 | $600 |
A load that is both oversize and overweight pays the overweight fee (28-1105(A)(3)). Height-only permits cost $15 per single trip over 14 ft or $45 a year per vehicle up to 14 ft on designated routes (28-1094).
| Class C load or service | Fee |
|---|---|
| 18 ft or less high and wide, 80,000 lb or less | $30 |
| 18 ft or less, over 80,000 lb | $90 |
| Over 18 ft high or wide, 80,000 lb or less | $40 |
| Over 18 ft, over 80,000 lb | $100 |
| Bridge analysis prepared by ADOT | $125 per 50-mile increment |
| Bridge analysis by a non-ADOT engineer, reviewed by ADOT | $75 per 50-mile increment |
| Tridem Class C | $75 plus a $15 review fee |
ADOT's Class C totals combine the $15 or $75 standard fee with a $15 review fee (18 ft or less) or $25 (over 18 ft). Analysis fees are paid before the analysis starts, and wrong weights can trigger a second paid analysis.
Envelope permits for non-specific loads up to 250,000 lb, 14 ft wide, 16 ft high and 120 ft long cost $150 for 30 days oversize, $500 for 30 days oversize-overweight, $750 a year oversize or $1,500 a year oversize-overweight (A.R.S. 28-1143). When ADOT and a city or county both require permits, the fee is paid only to ADOT (28-1105(C)). DPS escorts are billed separately through EZ DPS Escorts, at cost plus $4.00 per transaction.
Escort and pilot car rules in Arizona
Arizona has no statewide width-escort chart: escorts come from Table 4, route by route, and from permit conditions (R17-6-305(A)). Every escort operator must be trained and certified to Commercial Vehicle Safety Alliance standards or an equivalent program and recertify at least every 4 years (A.R.S. 28-1110), which puts Arizona among the certification states in our pilot car requirements by state table.
| Load | Escort requirement |
|---|---|
| Interstates, up to 14 ft wide | No width escort listed |
| Interstates and Phoenix-area freeways, over 14 ft to 16 ft wide (Class C) | 1 rear escort; I-17 MP 229.07–242.15 (Anthem Road to Rock Springs Road) needs front and rear |
| I-15, MP 0.00–29.40 | Over 14 ft wide, or over 100 ft long non-articulated: front and rear escorts plus 2 law enforcement escorts |
| Narrower state and US routes | Front and rear escorts from over 12 ft (e.g., SR 77, SR 82, SR 87, SR 260, SR 264, US 180), over 11 ft (US 60 MP 227.71–252.06) or over 10 ft (e.g., SR 73, SR 289, SR 386, US 89A over Navajo Bridge) |
| Law enforcement segments, over 14 ft to 16 ft wide | 2 officers on segments such as US 93 MP 91.38–193.61 and SR 260 from Star Valley to Show Low; 3 on SR 82 (MP 0.00–51.59) and SR 87 to Winslow |
| US 60 MP 252.06–318.14, US 70 to SR 73 (Apache Bridge) | Loads over 14 ft wide prohibited |
| Overhang over 20 ft at the front or rear | Front escort, rear escort, or both when both ends exceed 20 ft (R17-6-307(C)) |
| 3:00 AM to half an hour before sunrise | Rear escort over 11 ft to 14 ft wide; front and rear over 14 ft to 16 ft; front escort with a height pole over 15 ft high (R17-6-402(D)) |
| Curfew hours on SR 24, SR 202, SR 101 and Tucson's SR 989 | Over 10 ft to 12 ft wide: rear escort; over 12 ft: no movement (R17-6-404) |
| Two or more permitted loads traveling together | At least 1 escort per load; otherwise loads keep 2,000 ft apart (R17-6-305(A)(3), R17-6-401(B)(3)) |
Request Arizona DPS escorts at least 12 hours ahead (602-223-2855); if DPS cannot provide them, uniformed certified officers may be used if at least one is certified to enforce the FMCSRs (R17-6-306). Where several excess dimensions would require more than two law enforcement escorts, two are enough unless a Class C permit says otherwise (R17-6-412(E)).
| Bridge | Condition |
|---|---|
| Glen Canyon (US 89), Navajo (US 89A), Burro Creek (US 93), Virgin River #5 (I-15), Apache and Mallory Draw (US 60), Roosevelt Lake (SR 188), Coal Mine Canyon (SR 73), San Pedro River (SR 82) | 150,001–250,000 lb: road closure directed by 2 law enforcement escorts, center of the bridge, 10 mph or less; over 250,000 lb, ADOT Bridge Group analysis |
| Queen Creek and Cedar Canyon (US 60), Midgley (SR 89A), Santa Maria River (SR 96), Freeport-McMoRan Viaduct (UX 191) | The same conditions from 100,001 lb, and a Class C permit over 150,000 lb |
The escort vehicle is a registered, insured passenger car or two-axle truck with an OVERSIZE LOAD sign at least 5 ft by 12 in with 6 in letters above the roofline and a radio with at least 1/2 mile range, and it runs no more than 1,500 ft from the load on open highway or 250 ft in urban areas. Operators who direct traffic need at least $500,000 in commercial liability insurance, and other states' certificates are accepted (A.R.S. 28-1110).
Travel times, curfews and holidays
Arizona splits travel by size. Loads up to 10 ft wide, 14 ft 6 in high, 10 ft of front or rear overhang, 120 ft long and 250,000 lb may travel 24 hours a day, 7 days a week, subject to Table 4 (R17-6-401(A)); larger loads move from half an hour before sunrise to half an hour after sunset.
- Early start: loads that lose continuous travel only because of width (over 10 ft to 16 ft) or height (over 14 ft 6 in to 16 ft), and stay within 120 ft and 250,000 lb, may start at 3:00 AM on Table 4 routes marked R17-6-402, mainly the Interstates, Phoenix and Tucson freeways and much of US 60, and may run non-holiday weekends on those routes (R17-6-402).
- Phoenix curfew, 7–9 AM and 4–6 PM weekdays: no movement over 10 ft to 16 ft wide on I-10 MP 133.98–161.35, I-17 MP 193.94–214.96, SR 51, SR 143, SR 202 MP 0.00–9.80, the SR 202 Spur to Sky Harbor Blvd and US 60 MP 148.90–190.51 (R17-6-404).
- Tucson curfew, same hours: no movement over 10 ft to 16 ft wide on I-10 from Marana Road to Kolb Road, I-19 from Valencia Road to I-10, SR 77 from Miracle Mile to Tangerine Road, SR 86 and SR 210. City of Tucson streets also stop 7–9 AM and 4–6 PM weekdays and on 11 city holidays, with weekend moves only by the police chief's special permission.
- Class C weekends: on six Table 4 corridors, including I-17 north of Carefree Highway, US 60 from SR 79 to US 70 and US 93 from I-40 to Wickenburg, Class C loads may not move from noon Friday to 3:00 AM Monday (R17-6-407).
- Weather: no permit move with visibility under 500 ft from dust, snow, fog or heavy rain, with snow, ice or flooding on the road, or in winds that destabilize the load, and drivers obey official advisories that bar OS/OW moves (R17-6-405).
- Clock: permit hours run on Mountain Standard Time, except on state routes through tribal nations that observe daylight saving time (R17-6-101).
- Frost: no spring-thaw limits apply in Arizona; Table 4 lists seasonal closures on high-country routes such as SR 67 to the North Rim, SR 261, SR 273, SR 366 and SR 473.
| Holiday | Stop | Resume |

The rule covers loads over 10 ft wide (11 ft for self-propelled cranes and drilling rigs), 14 ft 6 in high, 10 ft of overhang, 120 ft long or 250,000 lb; loads within the continuous-travel envelope may move on holidays. Travel resumes half an hour before sunrise, or at 3:00 AM for early-start loads. The dates apply the rule to the 2026 calendar; ADOT publishes the rule, not dates.
What catches carriers in Arizona
Utilities over 16 ft
Over 16 ft high, the permittee notifies the utilities with lines over the route, and Class C applicants verify overhead utility and cable clearances. Moving any highway feature, such as signs, guardrail or signals, needs a separate ADOT encroachment permit.
A.A.C. R17-6-211(B), R17-6-308; A.R.S. 40-360.43
Check AZ511 before every trip
Permittees must check ADOT's website and AZ511 for route updates before each trip, and ADOT may temporarily prohibit movement or add conditions for construction, incidents or emergencies shown on AZ511.
A.A.C. R17-6-401(G), R17-6-412(A), (C), (F)
Nevada permits the Hoover Dam bypass
The Mike O'Callaghan-Pat Tillman Memorial Bridge on US 93 is permitted by Nevada, not ADOT, and DPS escorts across Glen Canyon Dam at 150,000 lb are booked at 602-223-2588.
Table 4, US 93 MP 0.00; ADOT routing contacts
Cranes get their own envelope
Self-propelled cranes and drilling rigs qualify for continuous travel up to 11 ft wide, and their curfew and holiday thresholds start at 11 ft, but crane permits are non-transferable and non-refundable, so the permit is ordered for the exact unit booked for mobile crane transport.
A.A.C. R17-6-205, R17-6-403, R17-6-404
Engineering analysis, envelope permits, ports and local roads
Above 250,000 lb, or outside Table 4's limits, an Arizona permit turns on engineering and paperwork more than on fees.
Bridge analysis
Engineering analysis is required over 250,000 lb, over the R17-6-411 axle tables or over a Table 4 bridge restriction (R17-6-104(B)), and ADOT Bridge Preservation analysis can take up to two weeks and needs certified weights. An applicant may instead submit an analysis by an Arizona-registered structural or civil engineer prepared to the AASHTO Manual for Bridge Evaluation, AASHTO LRFD and ADOT's guidelines, and an analysis ADOT approved in the previous 12 months may be resubmitted for an identical load on the approved route if the structures have not changed.
Permit axle weights
R17-6-411 sets group weight at 1.5 × 700 × (L + 40) for axle spreads of 3 ft 5 in to 18 ft, raised by up to 25% for wider axles (up to 10 ft) and 8 tires per axle. A single axle runs from 28,000 lb (8 ft wide, 4 tires) to 35,000 lb (10 ft wide, 8 tires), and a 4 ft tandem from 46,200 to 57,750 lb. Class C tridems may carry 60,000 lb with at least 4 tires per axle and set spacings (R17-6-212).
Envelope permits
Envelope permits cover non-specific, non-reducible loads up to 250,000 lb, 14 ft wide, 16 ft high and 120 ft long, with unlimited trips for 30 days or a year, but not mobile or modular homes (A.R.S. 28-1144). Annual tridem envelopes need an electronic trip-authorization number before each move, and holders keep records for 3 years under a points-based suspension system (R17-6-505, -507, -508).
ADOT ports of entry
ADOT's ports include St. George (I-15), Kingman (US 93), Topock and Sanders (I-40), Ehrenberg and San Simon (I-10), Yuma (I-8), Page, Fredonia, Teec Nos Pos, Parker, Douglas, Nogales Mariposa and San Luis II. They check registration, taxes, size and weight, CDL, insurance and equipment and issue permits in person, with hours varying by port; Teec Nos Pos observes daylight saving time.
Local and tribal roads
County, municipal and tribal routes need separate permission from that government (R17-6-105), and ADOT's routing contacts list the Navajo Tribal Council at 928-729-7224. The Salt River Pima-Maricopa Indian Community limits commercial vehicles over 10,000 lb GVW to its adopted truck routes and requires an ECS haul permit for construction and demolition haulers (480-362-7910). City of Tucson permits come from the Tucson Police Department; moves over 250,000 lb there need a professional engineer's route analysis, and route review takes at least 3 business days.
Tunnel, canyon and North Rim limits
The US 60 Queen Creek Tunnel (MP 228.47) carries a 14 ft height restriction, and loads over 14 ft to 16 ft high need front and rear escorts plus 2 law enforcement escorts, a road closure and the tunnel center. SR 89A from SR 179 to Oak Creek Vista needs a Class C permit over 50 ft long, and SR 67 to the North Rim is legal weight only (Class C over 80,000 lb) and closes seasonally.
Crossing into a neighboring state
- California, on I-10 at Ehrenberg or I-40 at Topock: Caltrans charges a flat $16 for a single trip good for 7 days, sets pilot car counts by each highway's route color, and regulates the pilot car's equipment rather than certifying the driver. The California route-color permit rules list the counts.
- New Mexico, on I-10 past San Simon or I-40 past Sanders: NMDOT requires escort vehicles to be inspected and certified before they enter, and an uncertified one stops outside the state. Its continuous-travel envelope uses Arizona's 10 ft and 14 ft 6 in but caps weight at 140,000 lb; see New Mexico oversize permit rules.
- Utah, on I-15 at St. George or US 89 at Kanab: UDOT wants the permit before entry except at three ports, St. George northbound among them, and its holiday ban starts at 2 PM the day before rather than Arizona's noon. Our Utah oversize permits page has the pilot certification rules.
Arizona oversize permit questions
What is Table 4 in Arizona's oversize regulations?
Table 4 is the route restriction list in A.A.C. R17-6-412, which ADOT keeps as a master list (as of July 10, 2025). It sets escorts, law enforcement escorts, bridge weight conditions, closures and the routes open for 3:00 AM or weekend movement, segment by segment. Because Arizona has no statewide width-escort chart, Table 4 decides most escort requirements, and permittees check it with AZ511 before each trip.
What do ADOT Class A and Class C permits cost?
A Class A single trip costs $15 for oversize only or $75 for overweight or oversize and overweight, up to 250,000 lb (A.R.S. 28-1105). Thirty-day permits are $30 or $75 and annual permits $360 or $600. Class C permits run $30 to $100 by size and weight, and ADOT bridge analysis adds $125 per 50-mile increment. DPS escorts are billed at cost plus $4 per transaction.
Must Arizona escort operators be certified?
Yes. Under A.R.S. 28-1110, every escort operator must be trained and certified under a program meeting Commercial Vehicle Safety Alliance standards or an equivalent, be 18 or older, hold a valid license and recertify at least every 4 years. Arizona accepts other states' certificates, but those do not authorize traffic control except as ADOT rules allow, and operators who direct traffic need $500,000 in liability insurance.
What is a Class C permit in Arizona?
Class C is Arizona's superload permit: it covers non-reducible loads over any Class A limit (14 ft wide, 16 ft high, 120 ft long or 250,000 lb), over the R17-6-411 axle tables or a Table 4 restriction. It is single trip only, applied for in ePRO to the Class C Unit, averages 48 hours to issue and is valid four working days. Over 250,000 lb, a bridge analysis is required.
How do I order an Arizona permit in ePRO?
Arizona permits are ordered in ADOT ePRO at adotepro.azdot.gov, through a national permit service, by mail, or in person at a port of entry or the Central Commercial Permits Office at 14370 W. Van Buren St. in Goodyear. ADOT does not sell permits by phone; for questions, the office lists 602-771-2960 and [email protected], and the Class C Unit 602-712-8280.
Can an Arizona permit load start before sunrise?
Yes, from 3:00 AM, for loads up to 16 ft wide or high on Table 4 routes marked R17-6-402, which may also run on non-holiday weekends, with escorts in the pre-dawn hours. Loads up to 10 ft wide, 14 ft 6 in high, 120 ft long and 250,000 lb may travel 24/7, weekends included. Other night or weekend moves need Class C approval, and six corridors bar Class C loads from Friday noon to Monday 3:00 AM.
Which Phoenix freeways have oversize curfews?
Monday to Friday, 7 to 9 AM and 4 to 6 PM, loads over 10 ft wide may not move on I-10 from the SR 101 Loop to the SR 202 Loop, I-17 from I-10 to the SR 101 Loop, SR 51, SR 143 and US 60 from SR 101 to SR 202 (R17-6-404). On SR 24, SR 101 and most of SR 202, loads 10 to 12 ft wide may move with a rear escort.
