    The rule in full12 official sources

    General width: 8′6″

    8′6″ on the designated State Highway System; current Table 4 can restrict a road to 8′.

    Loaded height: 13′6″–14′

    13′6″ general statutory limit; designated highways may allow 14′. Current Table 4 and posted clearance can be lower.

    NN semitrailer: 57′6″

    Federal National Network allowance for a tractor with one semitrailer. Longer trailers may qualify under state axle-position and route rules; local roads can differ.

    Overall length: No NN cap*

    *For a tractor with one compliant semitrailer on the National Network. Other combinations, trailers, projecting loads and local access have separate limits; see the state measurements below.

    Interstate weight: 80,000 lb*

    *Federal baseline, subject to the bridge formula, registration and postings: 20,000 lb single axle and 34,000 lb tandem. A particular configuration may have a lower limit; state grandfather allowances need verified spacing and route eligibility.

    Width & height by road

    Width is 8′6″ on the designated State Highway System unless Table 4 restricts the route to 8′. General statutory height is 13′6″; designated routes can allow 14′, but Table 4 and posted clearances can be lower. Check each road on the proposed route.

    Length

    Length limits depend on the vehicle type and the road network. Common limits: 40′ for a straight truck; 57′6″ for a semitrailer on the National Network; 53′ semitrailer or 65′ overall on other routes; 28′6″ for each short trailer in doubles.

    Load overhang

    Table 1 allows 3 feet of front overhang and 6 feet of rear overhang. Car haulers, manufactured homes, fiber and forage loads, poles and structural loads are measured differently. How far the load sticks out to the side decides Class A or Class C.

    Weight limits

    Legal limits are 20,000 lb on a single axle, 34,000 lb on a tandem and 80,000 lb gross with five or more axles. Gross weight alone does not make a load legal. Also check the bridge formula, every axle group, spacing, tires, ratings, Table 4, posted bridges and the route.

    Extra weight for idle-reduction and clean-fuel trucks

    Idle-reduction equipment can add up to 550 lb, or its certified weight if less. Carry the written weight certificate and proof the unit works. Natural-gas, battery-electric and hydrogen trucks can add the extra weight of the power system, up to 82,000 lb gross. Axle, bridge, rating, posted and route limits still apply.

    Width

    Table 1 allows 8′6″ on the designated State Highway System. Table 4 can limit a route to 8′. A.R.S. § 28-1093 sets other widths for other roads and for RV fixtures.

    Height

    Without a permit, height is 13′6″ under state law. Designated highways can allow 14′, and Table 1 uses 14′ on the State Highway System. Table 4 can lower a route to 13′6″ or another clearance.

    Axle limits: legal and with a permit

    Legal: single 20,000 lb. With a permit: single (8′ axle width, 4 tires per axle) 28,000 lb, tandem (4′ spacing, 8′ axle width, 4 tires per axle) 46,200 lb, tridem (class c tridem configuration) 60,000 lb. Permit axle-group weights come from Tables 3.01–3.09: W = 1.5 × 700 (L + 40) for groups 3′5″ to 18′ long, raised 15% for eight tires per axle and more for wider axles. The Class C tridem permit needs four tires per axle (or two 14″ tires), at least 8′ out-to-out axle width and 9′–14′ between the first and third axles.

  2. 02Requirements

    What official sources leave open8

    Where Arizona’s official sources disagree or say nothing, confirm with the agency before dispatch.

    • Arizona sets no statewide daytime escort chart by width, height or length; ADOT sets escorts on each permit and in route-specific Table 4 entries. The fixed escort rules found are the night-move rule (3:00 a.m. to half an hour before sunrise), the over-20′ overhang rule and the Phoenix/Tucson curfew-route rule.
    • Height: A.R.S. § 28-1094(A) sets 13′6″ without a permit, with 14′ on designated highways; R17-6-102 Table 1 sets 14′ (13′6″ on Table 4 restricted routes).
    • Width: A.R.S. § 28-1093(A) sets 8′ generally and 102 inches on Interstates, federal-aid and designated state highways; Table 1 sets 8′6″ (8′ on Table 4 restricted routes).
    • Thanksgiving 2026 and Memorial Day, Labor Day and Thanksgiving 2027 are not dated by ADOT (the rule names the holidays only), so those dates are not listed.
    • No ADOT source found on carrying the permit electronically.
    • The posted Arizona Administrative Code chapter is Supp. 22-2 (June 30, 2022); Table 4 is updated separately on azdot.gov, so check the current Table 4 and AZ511 before each trip.
    • Arizona has no separate 'superload' label; loads above Class A limits go through Class C review case by case.
    • The ADOT Local Counties and Cities page lists a DPS office 'for Requesting Escorts Across Glen Canyon Dam at 150,000 lbs' but states no rule; the rule itself was not found in the posted chapter.

    The rule in full11 official sources

    State highways

    ADOT permits cover only the State Highway System and the route on the permit. On state, U.S. and Interstate highways alike, still check Table 4, bridges, work zones, closures and the permit conditions.

    Local & other road authorities

    Get separate approval for every county, city, tribal, federal or private road on the route. ADOT's contact page lists Phoenix, Tucson, the counties, Navajo Nation, AZ511, maps and trip evaluation. Check it each time; contacts change.

    When a permit is needed

    A load over a Table 1 limit on an ADOT route normally needs the permit in hand before it moves. First settle the vehicle class and setup, any exemption, rail crossings, who owns each road, the axle weights and the posted limits.

    Class A permits

    Class A is the standard permit for a nondivisible load up to 14′ wide, 16′ high, 120′ long and 250,000 lb, within the permitted axle-group limits. It comes as a 96-hour, 30-day or annual permit.

    Class C permits

    A move goes to Class C review when it exceeds any Class A size, weight, axle or route limit, or the Class C side-projection limit. Send the exact addresses, route, an axle and load drawing, certified weights when asked, and any traffic or engineering material ADOT requests.

    How long permits last

    Class A lasts up to 96 hours. Class C lasts four working days. 30-day, annual, envelope and special permits each have their own terms. The dates and extension rules on the permit control.

    What to apply with

    Have ready the company details and credentials, the load and why it cannot be split, origin and destination, and the requested route. Add truck and trailer plates and VINs, overall length, width, height, overhang, weight and axle count. For overweight loads add every axle spacing, width, tire count and axle weight. Class C also needs a detailed route and drawing.

    Class A load limits

    Class A covers loads up to 14′ wide, 16′ high, 120′ long and 250,000 lb, with the axle limits in R17-6-411. These are the permit's limits; they do not open every route.

    Class C: larger loads

    Arizona has no single superload chart. Loads above Class A limits go to Class C staff, who set the route, structure, traffic, escort, contingency, analysis and certified-weight requirements for each move.

    Engineering review

    Engineering review is required over 250,000 lb, above the axle table, or above a bridge restriction. ADOT says the analysis can take up to two weeks. Wrong certified weights can mean a new analysis and a new fee.

    Class C permit

    Class A permits cover nonreducible loads within all of these limits; bigger nonreducible loads need a Class C permit: 14′ wide. 16′ high. 120′ long. 250,000 lb gross.

    Engineering analysis

    ADOT requires a bridge engineering analysis for an overweight load that is: Over 250,000 lb. Over the R17-6-411 permit axle-group weights. Over a Table 4 bridge weight restriction. Fee: $125 per 50-mile increment if an ADOT engineer prepares it; $75 per 50-mile increment if an outside engineer prepares it and ADOT reviews it.

    Class C timing and validity

    Class C permits average 48 hours to issue, not counting evenings, weekends and state holidays, and are valid for four working days. Extensions past four working days only for bad weather or equipment breakdown. Valid on state and Interstate highways only; check local jurisdictions for other roads. Certified weights are required; wrong weights can mean a second analysis and a new fee. After the permit is issued, schedule any required law enforcement escorts with the DPS Escort Scheduler.

    Route survey and contingency plan

    If ADOT sees a traffic safety risk in a Class C move, the applicant must submit a route survey and contingency plan. Roadway features and obstructions along the route. Pullout points by highway and milepost. Travel speed, transit times and a breakdown plan.

    Side projections

    Under a Class A permit, a load 12″ or more deep may stick out up to 3′ on either side, and a load less than 12″ deep up to 2′.

    County, city and tribal roads

    A load can move 24/7 if it is no more than 10′ wide, 14′6″ high, 10′ front and 10′ rear overhang, 120′ long and 250,000 lb. It must meet every one of these limits. Table 4 and the permit can still restrict it.

    Early starts and weekends

    On select Table 4 routes, loads over 10′ up to 16′ wide, or over 14′6″ up to 16′ high, and up to 120′ and 250,000 lb, can move from 3:00 a.m. to half an hour after sunset. This includes non-holiday weekends. Escorts are required, and the route and permit must allow it.

    Holiday stops

    Loads over 10′ wide, 14′6″ high, 10′ front or rear overhang, 120′ long or 250,000 lb stop for New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. The noon stop and restart times depend on the weekday.

    Phoenix and Tucson rush hours

    Loads over 10′ wide face weekday limits on listed Phoenix and Tucson routes, 7:00–9:00 a.m. and 4:00–6:00 p.m. On some segments, loads 10′ to 12′ wide need a rear escort; on others they cannot move.

    24/7 needs every limit

    24/7 travel needs all of these: up to 10′ wide, 14′6″ high, 10′ front and rear overhang, 120′ long and 250,000 lb, plus Table 4 and the permit. Know your overhangs and route before you count on it.

    Daylight hours

    Loads above the 24/7 limits move from half an hour before sunrise to half an hour after sunset. Local and tribal time, route limits, the permit's hours, escorts, holidays, weather and curfews can shorten that window.

    Starting at 3 a.m.

    Loads within 16′ wide or high, 120′ and 250,000 lb can start at 3:00 a.m. on select routes, including non-holiday weekends. Before sunrise, the escort rules for that size apply. This is not night permission statewide.

    2026 holiday stops

    For loads over 10′ wide, 14′6″ high, 10′ front or rear overhang, 120′ or 250,000 lb, holiday stop and restart times depend on the weekday. In 2026 travel stops: Memorial Day, noon May 22; Independence Day, noon July 2; Labor Day, noon Sept. 4; Thanksgiving, noon Nov. 25; Christmas, noon Dec. 24.

    Phoenix & Tucson travel hours

    On listed Phoenix and Tucson routes, loads over 10′ wide have weekday limits from 7:00–9:00 a.m. and 4:00–6:00 p.m. Some segments allow 10′ to 12′ loads with a rear escort; others ban all loads over 10′.

    Weather & visibility

    Stop when visibility is under 500 feet, the road loses normal traction, high winds or falling objects make the load unstable, or officials ban travel. A permit never overrides an unsafe-condition stop.

    24/7 travel

    Loads within all of these limits may travel around the clock where Table 4 allows: 10′ wide. 14′6″ high. 10′ front and rear overhang. 120′ long. 250,000 lb. Cranes and similar self-propelled equipment: up to 11′ wide.

    Night and weekend moves

    Loads over 10′ to 16′ wide or over 14′6″ to 16′ high (120′ and 250,000 lb max) may move on non-holiday nights and weekends from 3:00 a.m. on Table 4 night routes. Only on routes Table 4 authorizes for night and weekend transport. Night escorts (3:00 a.m. to half an hour before sunrise): over 11′–14′ wide rear; over 14′–16′ front and rear; over 15′ high front with height pole.

    Phoenix and Tucson curfews

    Loads over 10′ wide face weekday rush-hour limits on listed Phoenix and Tucson routes. Some routes: over 10′–12′ needs a rear escort, over 12′–16′ may not move. Other routes, including I-10, I-17 and US 60 segments: over 10′–16′ may not move. Cranes and similar equipment: curfew applies over 11′ wide.

    Class C weekend stop on listed routes

    On Table 4 routes marked for it, Class C loads may not move from noon Friday until 3:00 a.m. Monday.

    Weather stop

    Stop when visibility drops under 500′, when snow, ice or flooding reduces traction, or when high wind or falling objects make the load a danger to the road or traffic.

    Christmas 2026

    Christmas falls on a Friday: loads over 10′ wide, 14′6″ high, 10′ front or rear overhang, 120′ long or 250,000 lb stop at noon Thursday, December 24 and may resume Monday, December 28 at half an hour before sunrise (3:00 a.m. if eligible for night travel).

    The rule in full4 official sources

    Oversize signs

    At 9 feet wide or more, mount OVERSIZE LOAD signs on the front or roof and on the rear. Keep them readable and visible. Cover them when you are not hauling a permitted load.

    On the road

    Check the route each day. Drive at the lower of the permit or posted speed. Follow the permit's lane and spacing rules. Do not remove signs or other highway features without approval. Get encroachment approval where needed, and plan safe stops and pullouts.

    Utility coordination

    Tall Class C loads need clearances checked on the ground. When lines cross the route and the load is over 16 feet, or over a lower height set for that route, notify the utility. Any work in the right of way needs encroachment approval.

    Securing the load

    Load, tie down and, when required, cover the cargo so nothing can drop, leak, shift or come loose. Narrow exceptions exist for traction sand, maintenance water, loose farm leaves and stems, and on-farm use. Use one only if every condition fits.

    Carrier safety rules

    The permit holder and driver, and public snow-removal crews under R17-6-102(D), must follow the motor-carrier safety rules in 17 A.A.C. 5 Article 2 where they apply. A size permit does not replace carrier and driver compliance.

    Warning flags

    Flags on overwidth or overlength loads are cloth or plastic, at least 18″ square, red or fluorescent orange, placed as shown in Illustration 1.

    Night safety lighting

    At night, a load sticking out more than 4″ past the vehicle's width or more than 4′ front or rear needs safety lighting per Illustration 4.

    The rule in full13 official sources

    Special permits

    Arizona has separate permits for many named loads: Class A and Class C loads, envelopes, designated-route height, commercial RVs, cranes and drilling rigs, and road machinery. Others cover fiber and forage module movers, border combinations, LCVs, wide watercraft, Lake Powell houseboats and Class C tridems. Mobile homes, public snow removal, forest biomass, military, nuclear and bulk-milk loads, emergency relief and towing have their own. The type of cargo alone does not qualify a load.

    Mobile-home permits

    A mobile-home move needs the right permit, the serial number, maker and model, a tax clearance or new-home bill of lading, and the route and axle details. The Easy C permit covers up to 16′ wide or high, 120′, 80,000 lb and legal axle groups, on ADOT roads only.

    Cranes

    A crane or drilling-rig permit covers one exact setup and its weight papers. Changing the boom, dolly, counterweight, trailer, size or weight can void it. Its 24/7 width limit differs from ordinary loads.

    Longer combination vehicles

    Class E permits for longer combination vehicles carrying divisible loads are limited to named northern routes and setups. Length, weight, lane, bridge-formula, weather, Port-of-Entry and permit conditions all apply.

    Boat & watercraft moves

    Wide boats, personal-watercraft lake access and Lake Powell houseboats each have their own permit. Check registration, the lake or launch distance, route, size, weight, notice, daylight and holiday limits, and whether you need an envelope or special permit.

    Public snow removal

    Only state, county, city or town crews qualify, driving their own equipment to clear snow and ice, make repairs or load deicer. Article 3 safety duties and carrier safety rules still apply. Private snow contractors do not qualify by default.

    Forest and biomass loads

    The healthy-forest permit needs a qualifying forest-health or fuel-reduction project and natural forest or biomass cargo. It also needs the set Class A or tridem setup, an ADOT-maintained route, and engineering, traffic and bridge reviews. It is not a general timber or farm exemption.

    Nuclear, military, emergency and milk loads

    Spent-nuclear casks, emergency-response vehicles, marked military equipment and bulk milk count as nondivisible under R17-6-103(I). Confirm the cargo, vehicle class, markings or mission, route, and axle and bridge details. The permit, not the cargo label, allows the move.

    Towing permits

    Towing rules depend on the disabled vehicle, how it is towed, safety equipment, the operator's license, distance, route and any special permit. The towing exception does not cover ordinary loads, even on a wrecker.

    Farm equipment

    Farm rules apply clause by clause. § 28-1098(C) covers vehicles used for farming on a farm; subsection A(3) covers only loose leaves and stems. Husbandry, forage and fiber overhang, transporters, weight, forest and permit rules each have their own conditions. ‘Agricultural’ is not a blanket exemption.

    Class A trip, 30-day and annual permits

    Class A permits come as single-trip, 30-day or annual, for state routes only. Oversize: $15 single trip, $30 for 30 days, $360 annual. Oversize/overweight: $75 single trip, $75 for 30 days, $600 annual.

    "Easy" C mobile home permit

    Mobile homes within 16′ wide, 16′ high, 120′ overall and 80,000 lb, inside axle limits, can get an Easy C permit with no bridge analysis. Valid only on ADOT roadways; check local jurisdictions for other roads.

    Cranes and drilling rigs

    Self-propelled cranes, drilling rigs and similar equipment on a Class A crane permit may travel around the clock up to 11′ wide (other 24/7 limits unchanged), unless the metro curfew or Table 4 restricts it.

About the example equipment

The samples use ODPermit’s editable 48 ft flatbed · 5 axles planning profile. Loaded dimensions, gross weight, 100 state miles and Arizona registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.

Great Dane Freedom flatbed brochure — Drop-deck option: 20–26 in drop from the upper deck with a 40–34 in rear deck height, which gives the 60 in upper-deck planning height. Platform length, combined tare and tractor geometry are editable ODPermit assumptions.
