Super Loads / Overweight Loads Office

Functions of the Overweight / Super Loads Division


Two vital functions of the Overweight / Super Loads division involve the permitting of over-width / overweight loads and monitoring and oversight of the self-issuing permit program.

The office not only permits these loads but also establishes the routes that the carrier will be required to take, both in the interest of safety and to also minimize highway wear and tear. 

The self-issuing permits program allows qualified Wyoming Resident companies to issue their own trip permits to travel to Wyoming destinations and to cross the state. 

You may contact the Overweight Loads Office between the hours of 8:00 am - 5:00 pm Monday through Friday at 307-777-4376. 


Utility Contact Information

All utilities, cities and counties must be contacted for authorization and/or permission to travel the route proposed by the carrier, for any vehicle and/or load 18 feet or greater in height.

You must contact all utilities (i.e. telephone, cable TV, power), cities and counties (if using county roads) along the route and furnish the Wyoming Highway Patrol, Overweight Loads Office, with the following completed form.

Please print out the utility contact form listed below and send back to Overweight Loads office after all notifications are filled out. The form can be faxed to (307) 777-4399. Make additional copies of this form if necessary.

Self-Issuing Permits

Class C (Self-Issuing) Policies


All companies applying for, and participating in, the Self-Issuing permit program are required to read, sign and abide by the policies and procedures described in this document as well as all other requirements of the Self Issuing Program. Training will be provided outlining precise procedures for completion, submission and accounting of permits. This training will also define procedures for movements using self issuing permits as well as program prohibitions. After you have signed this document you will be given a copy for your records. It is the responsibility of the company to insure all personnel involved in the use and preparation of Self-Issuing permits are aware of those policies and procedures included in the program.

As noted on the Self-Issuing permits, all permitted loads shall stop at the first available port of entry which would not exceed 5 miles from the declared route and any Port of Entry along the route if directed by a regulatory sign. This is not an option or suggestion, it is a requirement. Failure to stop at required Ports of Entry is cause for cancellation from the Self-Issuing program. Loads that have stopped and weighed at a highway shop are not exempt from stopping at the first available Port of Entry. Whether legal weights or not, all loads to be moved with self-issuing permits shall weigh at the first available certified scale along the route which would not exceed five miles from the declared route of travel.           

When the size or weight exceeds Class B/C limits (See Chapter 5 of WYDOT Motor Carrier Rules and Regulations) the Overweight Loads Office shall be contacted to obtain authorization for movement of the vehicle or load. An authorization number will be issued and must be indicated here along with the name of the individual granting approval. The Self-Issuing permit number to be used will be required.

No changes or alterations are allowed on permits. Any change made on a permit (without proper authorization) automatically voids the permit. Operating with a permit on which changes have been made is essentially operating without a permit, which may result in the driver being cited. If it is necessary to change or alter a Self-Issuing permit, contact the Overweight Loads Office for authorization otherwise void the permit. When a permit is VOIDED, Please write “VOID” In large letters on the face of the permit. Voided permits must have a brief explanation of why the permit was voided.  If a new permit will be written to replace the voided permit, write”replaced by and the replacement permit’s number” on the voided permit. On the replacement permit write “replaces permit and the voided permit’s number." Mail in the white and the blue copies of the voided permit with all of your company’s information filled in. Do not destroy or throw away any permit.

All necessary and applicable restrictions must be checked on the permit. If escorts are required, indicate the placement and number of escorts required.

The “Other" section may be used to add any additional restrictions or notes which are necessary to clarify information on the permit.

The individual completing the Self-Issuing permit must sign the permit. The individual may be anyone within the company who has been properly trained on the use and preparation of Self-Issuing permits and understands the policies and procedures concerning Self-Issuing permits. In all cases, the company to whom the permits are issued to is responsible for proper use and preparation of Self-Issuing permits.

Self-Issuing permits are a privilege not a guaranteed right. Permit privileges may be revoked without warning if Wyoming Department of Transportation deems it is necessary. Fraudulent or misuse of permits, failure to comply with the rules and regulations, unsatisfactory dot rating, unsafe operating practices, failure to stop at the Ports of Entry, traveling on restricted routes, continued mistakes or habitual late permits or payments, extended non use of permits are examples of reasons the Wyoming Department of Transportation may revoke your permit writing privileges.

Self-Issuing permits are valuable documents and must be accounted for at all times. If permits are lost or stolen the holder must supply a separate letter of disposition (I.e.., lost, destroyed, etc.,) for each lost or stolen permit. These letters will replace the effected permits(s) in the holders’ file. Any unaccounted for Self-Issuing permits reported as lost, destroyed, or stolen will result in a $100 permit fee assessed to the company. Lost or stolen permits will be considered null and void. This fee will be charged on the company’s next invoice. The fee is non refundable if a permit is located at a later date. All permits must be returned to the Overweight Loads Office immediately in the event your company has been canceled from the Self-Issuing permit program, you no longer require use of the permits or are no longer a Wyoming resident company. You will be charged for each permit that is not returned.


Please refer to the “Instructions for Completion of Self Issuing Permits” for additional information on the requirements of completing the permits.

Violations of the program and errors will result in the following sanctions for the offending company.


  1. The first violation of any regulations regarding self issuing permits will result in a company official being notified of the violation verbally or via email. This does not include violations of the “Self Issuing Requirements.” (see inclusion)
  2. The second violation of any regulations regarding self issuing permits, regardless if it is a violation of the same regulation originally violated or not, will result in a notification letter to the company outlining the violation and our expectations. This does not include violations of the “Self Issuing Requirements.” (see inclusion)
  3. A third violation of any regulation, or any violation of the “Self Issuing Requirements”, will result in the company having its self issuing privilege suspended for 90 days. During this suspension the agency will review the companies self issuing permit history to determine if additional training is necessary prior to reinstatement. Upon completion of the 90 day suspension the company shall write a letter requesting reinstatement to the Commercial Carrier Officer of the Wyoming Highway Patrol.
  4. If the company violates the regulations a third time or any subsequent violations of the “Self Issuing Requirements” within three years of the original violation they will receive a 180 day suspension. Prior to reinstatement a company member shall be required to attend a self issuing permit instructional class offered by the Wyoming Highway Patrol.
  5. Upon reinstatement the company will again start the violation process over. However if the third violation is reached the company will receive a 180 day suspension. Prior to reinstatement a company member shall be required to attend a self issuing permit instructional class offered by the Wyoming Highway Patrol.
  6. Any violations for a three-year period after the second suspension and reinstatement will result in a revocation of the privilege to have self issuing permits.
  7. Any violations deemed to be egregious, malicious or intentional shall be viewed on a case-by-case basis. If confirmed, these violations will result in a minimum 180 day suspension of self issuing privileges.
  8. The above listed rules (1 – 6) do not supersede processes spelled out in Subsection 15, paragraphs c and d, of the “Gold Book.”


  1. We are all human and we make mistakes. We have built a mistake clause into the Self-Issuing permit program by allowing a company to void a permit at no additional cost or penalty. An incorrectly completed Self-Issuing permit may be voided by a WYDOT permit issuing agent. There is no additional cost for this but it may be considered a violation of regulations. All voided permits shall be submitted to the Wyoming Highway Patrol OWL office within 48 hours.
  2. When a Self-Issuing permit is lost it must be reported to the Wyoming Highway Patrol OWL office within 48 hours of discovery. There is a non-refundable fee of $100 for each lost permit. This fee will be charged on the company’s next invoice. Once a permit is reported lost its reference number will be voided.
  3. Whenever practicable Self-Issuing permits shall be issued in numerical order.


  1. If you do not receive an invoice for Self-Issuing permit fees by the 15th of the month, please contact the Overweight Loads Office so a duplicate invoice can be sent.
  2. If payment for Self-Issuing permit invoices is not received in the Overweight Loads Office by the date due, Self-Issuing permit privileges will be suspended until the holder is notified that the payment has been received.
  3. Any two (2) delinquent payments within any twelve (12) consecutive months will result in an automatic ninety (90) day suspension of Self-Issuing permit privileges and possible re-training of company personnel in the use and preparation of Self-Issuing permits.
  4. The invoice (or a copy of the invoice) must be returned with the payment.
  5. Please do not combine Self-Issuing permit payments with any other payment due to the State of Wyoming.


Any participant in the Self-Issuing permit program whose permit privileges are suspended for 90 days has the following recourse:

  1. An informal meeting with personnel of the Overweight Loads Office and the Commercial Carrier Supervisor of the Wyoming Highway Patrol. A letter will be issued with a decision concerning the meeting. The suspended participant will have thirty (30) days from the date of the letter to request an Administrative hearing pursuant to Chapter 3 of the Wyoming Transportation Department Rules and Regulations.
  2. If the suspended participant is not satisfied with the decision of the Administrative hearing they can appeal to the District Court.

Participants should be aware that the suspension will be in effect throughout the duration of the appeal process.

Super Loads Application

Super Loads Application Form


This program has been developed to assist carriers in obtaining a SUPER LOAD authorization through the Office of Overweight Loads (OWL).  
Before sending a request, make sure you understand the following information:
·         Be sure to research your requested route to ensure the move is not affected by any restrictions or structures before submitting the request. Vertical clearances, width, and weight restrictions may be found on the Wyoming Department of Transportation web site or by clicking here.
·         The move must be in compliance with all Wyoming Statutes and Regulations governing oversize/weight movements. This information can be found on the Wyoming Highway Patrol web site or by clicking here.
·         The information must be true and accurate; if it is found to be incorrect by a permit issuer the driver may be issued a citation for the violation, and a new authorization will need to be obtained. When the authorization is issued, it will only be valid for the specific information requested on the Super Load Request.doc form.
·         Be specific, where a load starts or ends in Wyoming. Give a crossroad or milepost as to where you will be getting on or off the state highway system. Also, when you are using city or county roads as part of your route, be sure to indicate them on your request.
·         If the load is delayed, canceled or you need to make any corrections on a request, contact the OWL office ASAP by email. 
·         Loads over 18’ wide or high must be approved 24 hours before moving. Loads over 18’ wide will be restricted during school bus and mining hours. The approximate time the movement will start for these loads must be within 30 minutes.
·         To help us determine a route for loads that are over 16’ high, you will need to indicate if a load can be lowered and by how much to clear a structure. This should be noted on the form in the "comment/remarks/added restrictions" area.
·         Loads that require a bridge analysis will require additional forms from OWL that need to be completed and returned. These forms may be found on the Super loads/Overweight Loads Office web page. The bridge analysis may not be performed until OWL has received the completed forms.
HOW TO SUBMIT YOUR REQUEST: You must have Microsoft Word 97 or later to use the request form and have an email account. Your request may be sent at any time, and we will process them as soon as possible Monday - Friday, excluding holidays. Requests sent in after 4:00 p.m. will usually be handled the next business day. 
·      Download the Super Load Request.doc form below. Open the form and fully complete it. Save as a Word Document.
·      Send an email with the fully completed form attached. The subject line in your e-mail should show the Company name and the power unit plate number. 
The vehicle may NOT move on Wyoming highways until OWL sends you an authorization number.
