BID GUARANTY.

(a) The commission by rule shall provide a method by which a bidder may submit a bid guaranty. A rule may authorize the use of an electronic funds transfer, a check, including an electronic check, a money order, an escrow account, a trust account, a credit card issued by a financial institution chartered by a state or the United States or by a nationally recognized credit organization approved by the department, or another method the commission determines to be suitable. The department may require the payment of a discount or service charge for the use of a credit card.

(b) The department may establish one or more escrow accounts in the state highway fund for the prepayment of bid guaranties. The bid guaranties and any fees the department establishes to administer this subsection shall be administered in accordance with an agreement approved by the department. Notwithstanding any other law and as specified in the agreement, any available accumulated interest and other income earned on money in an escrow account shall be paid to the bidder or credited to the escrow account.

(c) The department shall deposit each administrative fee and discount and service charge collected under this section to the credit of the state highway fund.

(d) The commission's rules may not prohibit a bidder from submitting a bid guaranty by use of a cashier's check, money order, or teller's check.
