Applications for class C permits should ideally be submitted via the ADOT ePRO System.  They do have other options but we strongly suggest you use the method they prefer. While it’s not a 100% guarantee you can usually get a Class C permit in 48 hours (excluding evenings, weekends and state holidays). Once it is approved you will see pending/approved/refused when you log in. The fee is $30 for class C shipments that are no greater than 18 feet in height and/or width and 80,000 pounds. Shipments that are over 80,000 pounds are $90. Shipments that are over 18 feet in height and width, but not over 80,000 pounds, are $40. For shipments that are greater than 18 feet in height and width and/or 80,000 pounds are $100.  Typical class C permits are only valid for 4 working days unless otherwise specified. In order to obtain a class C permit extension beyond the 4 day working allowance you must either have inclement weather issues or equipment breakdown issues.
