Wyoming oversize and overweight permits come from the Wyoming Highway Patrol: ports of entry and highway shops for loads within the Class B and C limits (18 feet wide, 17 feet high, 120 feet long, 160,000 pounds gross), and the Overweight Loads Office in Cheyenne for anything bigger. A single-trip oversize permit costs 25 dollars plus 3 cents per foot per mile beyond 15 feet wide, 15 feet high or 75 feet long, and an overweight permit is 6 cents per ton per mile on the excess with a 40 dollar minimum. Legal limits are 8 feet 6 inches wide and 14 feet high, and gross weight can reach 117,000 pounds on the interstate under the Table I bridge formula.
Who issues what in Wyoming
The permit pages
Wyoming-specific requirements
Wyoming keeps intrastate trucking regulated at the state level: WYDOT issues permanent Letters of Authority for intrastate contract and private carriers, and every commercial vehicle must stop at a Highway Patrol port of entry on entering the state. There is no weight-distance tax, Wyoming is not a UCR member, legal height is 14 feet, and gross weight can reach 117,000 pounds on the interstate under the bridge formula.
Intrastate authority is permanent
A Wyoming Letter of Authority never expires and has no renewal fee: it stays in force until revoked for cause or cancelled by the holder. The catch for contract carriers is continuous insurance; a filed Form K cancellation suspends the authority on its effective date. See the state intrastate authority page (B1).
Contract carriers need authority at any weight
The 26,000 pound line only decides whether a private carrier needs authority. Anyone hauling for compensation between Wyoming points, including hot shots, float trip and hunting guides, and tow operators, needs contract authority and 750,000 dollars of Form E liability regardless of vehicle size.
USDOT number with a WY suffix
Wyoming intrastate carriers mark vehicles with their USDOT number followed by WY, for example USDOT 123456 WY, under Wyoming's amendment to 49 CFR 390.21(b)(2).
Every commercial vehicle stops at a port of entry
All commercial vehicles, transport operators, livestock haulers and deliveries into Wyoming must stop at a port of entry on entering the state, showing IFTA, registration or IRP at the correct Wyoming weight, a USDOT number for interstate moves, and operating authority for intrastate moves. PrePass vehicles with a green light may bypass unless hauling livestock or an oversize or overweight load.
117,000 pounds on the interstate
Wyoming allows up to 117,000 pounds gross on the interstate under the Table I bridge formula, and tandems carry 36,000 pounds rather than the 34,000 common elsewhere. On primary and secondary highways the operator can choose Table I or the 80,000 pound Table II.
Insurance certificates are not accepted
Wyoming does not accept ADCO or ACORD certificates, binders, abstracts or insurance ID cards for intrastate authority. The Form E, G, H, J, K, L and MC61E filings posted on the Intrastate Operating Authority page must be completed by a broker, underwriter or other authorized insurance company representative and emailed to WYDOT.
Weather classes for oversize loads
Oversize loads stop when the chain law is in effect or roads are closed to unnecessary travel, and WYDOT posts Class 1 to 4 restrictions keyed to wind and road conditions, with Class 1 covering mobile homes and light oversize loads.
Continuous registration and back fees
Wyoming is a continuous registration state: a vehicle whose registration lapsed is assessed back fees to bring it current when it joins an IRP account.
Cheap 96-hour trip permits
Carriers without Wyoming registration or IFTA can buy 96-hour trip permits at the first port of entry: 20 dollars per unit or 40 dollars per combination for registration, and 7.50 or 15 dollars for fuel.

More Wyoming rules that catch carriers out
- State carrier number: note
- WYDOT assigns each motor carrier a docket number when it grants authority (W.S. 31-18-209(e)); the vehicle itself shows the USDOT number with a WY suffix. See the state intrastate authority page (B1).
- Weight distance tax: note
- Wyoming levies no weight-distance or highway use tax. The credentials the Highway Patrol checks at ports of entry are IFTA, Wyoming registration or IRP, a USDOT number, and intrastate authority; WYDOT's IFTA Manual names Kentucky, New Mexico and Oregon as the jurisdictions with a highway use fee on top of fuel tax.
- UCR participation: summary
- Wyoming is not a member of the Unified Carrier Registration Agreement. Wyoming-based interstate carriers, brokers, freight forwarders and leasing companies register and pay UCR through a participating state: the state where they have an office or operating facility if it participates, otherwise one of CO, ID, MT, ND, NM, OR, SD, UT or WA.
- Intrastate driver age: detail
- WYDOT Motor Carrier rules Appendix A amends 49 CFR 391.11(b)(1) for intrastate carriage to read at least 18 years old, and changes the 395.1(e) short-haul exemption to a 150 air-mile radius.
- ELD intrastate adoption: regulation
- WYDOT Motor Carrier rules Chapter 1, Section 9(a)(iii) and Appendix A to Chapter 1
- ELD intrastate adoption: summary: text
- Wyoming adopts 49 CFR Part 395 for intrastate carriers through WYDOT Motor Carrier rules Chapter 1, Section 9(a)(iii), which takes 49 CFR Parts 40, 303, 325, 350, 355, 356, 360 and 365 through 399 for interstate transportation and as amended in Appendix A for intrastate transportation. Appendix A rewrites the federal short-haul paragraph, 49 CFR 395.1(e), for intrastate drivers: a driver is exempt from the requirements of 395.8 if the driver operates within a 150 air-mile radius of the normal work reporting location. That is the whole Wyoming text. The federal paragraph also requires the driver to return and be released within 14 consecutive hours, requires 10 consecutive hours off between shifts for a property-carrying driver, requires the carrier to keep 6 months of time records, and carries a separate (e)(2) rule for non-CDL drivers; the Wyoming version keeps only the radius. 395.8 is the record-of-duty-status section where the electronic logging device requirement sits, so a Wyoming intrastate driver inside the radius is released from logs and the ELD on radius alone. The rewrite touches 395.8 only: the driving and on-duty limits in 49 CFR 395.3 still apply.
- ELD intrastate adoption: adopted parts: value
- Section 9(a) requires all motor carriers as defined in W.S. 31-18-101, and carriers in interstate commerce as defined in 49 CFR 390.5, to comply strictly with the USDOT motor carrier safety regulations in 49 CFR Parts 40, 303, 325, 350, 355, 356, 360, and 365 through 399 for interstate transportation and as amended in Appendix A to the rules for intrastate transportation. Part 395 falls inside the 365 through 399 range. Appendix A's general cross-references make references to Interstate mean Intrastate, references to Federal mean Wyoming, and references to farms and farmers include ranches and ranchers.
- ELD intrastate adoption: adopted parts: regulation
- WYDOT Motor Carrier rules Chapter 1, Section 9(a)(iii); Appendix A cross-references (a) to (e)
- ELD intrastate adoption: short haul radius: value
- Appendix A: Section 395.1(e) is changed to read: (e) 150 air-mile radius driver. A driver is exempt from the requirements of 395.8 if: (1) The driver operates within a 150 air-mile radius of the normal work reporting location. Appendix A defines an air-mile as an international nautical mile of approximately 6,076 feet measured in a straight line and not on an over-the-road basis.
- ELD intrastate adoption: short haul radius: regulation
- WYDOT Motor Carrier rules Chapter 1, Appendix A, Section 395.1(e) and Section 390.5
- ELD intrastate adoption: short haul radius: federal comparison
- The federal 49 CFR 395.1(e)(1) exempts a driver from 395.8 and 395.11 only if the driver operates within a 150 air-mile radius (172.6 statute miles) of the normal work reporting location, returns to that location and, except a driver-salesperson, is released from work within 14 consecutive hours, has at least 10 consecutive hours off duty separating each 14 hours on duty (8 for a passenger-carrying driver), and the employing carrier keeps accurate time records for 6 months. Federal 395.1(e)(2) adds a separate rule for property-carrying drivers who do not need a CDL. The Wyoming intrastate text keeps the radius and drops every other condition, and it has no (e)(2).
- ELD intrastate adoption: hours limits unchanged: value
- Appendix A does not amend 49 CFR 395.3, so a Wyoming intrastate property-carrying driver runs the federal driving and on-duty limits: 10 consecutive hours off duty before driving, no driving after 14 consecutive hours on duty, an 11-hour driving limit, and the weekly limits in 395.3(b). The radius rewrite removes the record-of-duty-status requirement inside the radius; it does not waive the hour limits.
- ELD intrastate adoption: hours limits unchanged: regulation
- 49 CFR 395.3, adopted by WYDOT Motor Carrier rules Chapter 1, Section 9(a)(iii)
- ELD intrastate adoption: record of duty status: value
- Outside the Wyoming 150 air-mile radius, 49 CFR 395.8 applies to a Wyoming intrastate driver as adopted. Paragraph (a)(1)(i) requires a motor carrier operating commercial motor vehicles to install and require each of its drivers to use an ELD to record duty status in accordance with subpart B of Part 395, no later than December 18, 2017. The manual-log cases in paragraph (a)(1)(ii) are federal, and Appendix A adds none of its own.
- ELD intrastate adoption: record of duty status: regulation
- 49 CFR 395.8(a)(1), adopted by WYDOT Motor Carrier rules Chapter 1, Section 9(a)(iii)
- ELD intrastate adoption: agricultural growing season: value
- Appendix A, Section 390.5, defines agricultural growing season as January 1 to December 31 of any calendar year. The federal agricultural exception in 49 CFR 395.1(k) applies during planting and harvesting periods as determined by each State. The appendix does not name the provision the defined term modifies, and 395.1(k) uses the words planting and harvesting periods rather than growing season, so the link is recorded rather than asserted.
- ELD intrastate adoption: agricultural growing season: regulation
- WYDOT Motor Carrier rules Chapter 1, Appendix A, Section 390.5; 49 CFR 395.1(k)
- ELD intrastate adoption: hours relief requests: value
- Appendix A, Section 390.23: WYDOT directs any motor carrier seeking relief from Section 395.3(b) to contact the Wyoming Highway Patrol in writing to request such relief. WYDOT recognizes emergency relief exemptions declared by the President, the Governor of a state, or authorized designees when declared as prescribed in federal regulations.
- ELD intrastate adoption: hours relief requests: regulation
- WYDOT Motor Carrier rules Chapter 1, Appendix A, Section 390.23
- ELD intrastate adoption: intrastate driver age: value
- Appendix A changes 49 CFR 391.11(b)(1) for intrastate drivers to read: is at least 18 years old.
- ELD intrastate adoption: intrastate driver age: regulation
- WYDOT Motor Carrier rules Chapter 1, Appendix A, Section 391.11(b)(1)
- ELD intrastate adoption: notes
- Authored 2026-09-28 by reading WYDOT Motor Carrier rules Chapter 1 (effective 01/03/2023, the rules export the Highway Patrol posts, generated 05/20/2025) Section 9 and Appendix A in full, and 49 CFR 390.23, 395.1, 395.3, 395.8 and 395.11 through the eCFR (Title 49 up to date as of 09/24/2026). Which vehicles count as commercial for the adopted rules follows the Appendix A definition, which points to W.S. 31-18-101(a)(iii); the weight lines for intrastate authority are in the state intrastate authority page (B1).
Who issues permits
The Highway Patrol issues every Wyoming size and weight permit. Ports of entry and highway shops clear loads within the mid-size class limits, and anything beyond them goes to the Overweight Loads Office in Cheyenne, which approves the largest loads on weekday business hours only. The Highway Patrol also runs an online form to request permission to bring an oversize load straight to a port.
Before any permit issues, the vehicle needs valid base plates or registration, a USDOT number, and Wyoming authority where required.
The permit types Wyoming issues
Single-trip oversize permits pay a base fee plus a per-mile charge on each foot beyond the width, height, or length lines, and overweight permits pay per ton per mile on the excess, with a minimum. Class D extended permits run up to a year for equipment within a set envelope. Seasonal and commodity permits cover forest products, baled hay, combine headers, sugar beets, gravel, livestock, and prefabricated buildings.
Short-term registration and fuel trip permits for vehicles not plated or licensed for Wyoming sell at the first port of entry.
Daylight, holidays, and weather
Oversize moves are daylight only unless the permit or the Highway Patrol allows otherwise, with exceptions for some long single units and combinations. Escorted moves stop on the listed holidays and the nights around them, and a holiday that makes a long weekend closes the whole weekend.
Weather stops everything oversize when the chain law is on or roads close to unnecessary travel, and WYDOT posts weather classes that stop light, high-profile loads first. Overweight loads of legal size are not tied to daylight.
