ADOT Auction


There is no charge or entry fee to participate in the public auction: simply come in and fill out a bidder registration card. As the auction progresses, flash your bidder card at the auctioneer to indicate your bid on a particular item.

Auction items do not have minimum bids or reserve prices. An exception would be for items purchased on a “life cycle cost” solicitation. In such instances, ADOT bought equipment from a vendor with the agreement that the vendor would repurchase the equipment from ADOT for a predetermined price when the term of the contract expired. These items are normally heavy construction equipment, such as wheeled loaders, motor graders, etc.

If you are a bidder from out of state, Equipment Services will advise you of the total amount of your purchases for the auction. You can then mail us a cashier’s check, preferably using overnight delivery, for payment. Items purchased will not be released until payment is received.


You must wait one hour after the auction has concluded to pay for the items purchased. We have automated our auction procedures. All information, from bidder registration through bid tabulation, is entered into our database. When you come in to make a payment, the press of a key produces a purchase contract/receipt, bill of sale and odometer statement as applicable. We appreciate your understanding and cooperation.

We will accept payment in the form of cash, money order, certified check or cashier’s check. Money orders and checks should be made payable to the Arizona Department of Transportation. Personal checks and company checks will not be accepted.

A 7.3 percent sales tax will be added to the selling price of each item. Exceptions are allowed only upon presentation of a state-privilege (sales) license or state-use license. Bidders claiming tax exempt status will need to bring the original tax-exemption license with them at the time of bidder registration.
