Before a Class C Permit can be purchased, you must first request a Class C Approval. To request a Class C Approval, please follow the procedures listed below.

Please read carefully prior to submitting request form.

1. Complete the Class ‘C’ request form (please type or print). Ensure request form is complete and accurate. Incomplete or inaccurate information on request forms causes delays in processing approvals and issuance of a permit



2. Ensure that the company name is the same each time a request form is submitted to our office or the Motor Vehicle Division.



3. When obtaining permits through the Motor Vehicle Division, ensure that the dimensions, weights, truck unit numbers, etc. are the same as what was submitted to our office for a Class ‘C’ approval.



4. Fax the Class ‘C’ request form to (602) 712-3380.



5. Loads over 250,000 lbs. or overaxle weight are reviewed by the ADOT Bridge Operations section. Analysis could take up to two weeks.



6. This office can only forward Class ‘C’ approvals to a MVD port of entry or MVD Goodyear/Central, Tucson, Safford, Sierra Vista, Willcox or Benson office. Note on request form where approval is to be sent.



7. The Class ‘C’ approval is not a permit. Permits must be obtained through one of the MVD port of entry or the Goodyear/Central, Tucson, Safford, Sierra Vista, Willcox or Benson office.



8. Administrative fee for Class ‘C’ approval is in addition to the permit fee. ($15.00 for loads up to 18 feet in width or height, $25.00 over 18 feet). Additional fees may be required for certain bridges (R17-4-413, Appendix D).



9. Class ‘C’ approval is valid for 5 working days. An extension of time on an approval must be requested prior to the expiration date of an approval and before purchasing a permit.



10. Class ‘C’ approvals/permits are valid on State and Interstate highways only.



11. Normal time frame for the completion of a Class ‘C’ approval is three (3) days (72 hours, excluding weekends and holidays from the date and time the request is received). However, most approvals are completed within one to two days. To check if approval is completed earlier than the three (3) days, please contact the MVD port of entry or Permit office where you indicated approval was to be sent.
