Ladies and Gentlemen:

We have acted as counsel to Duos Technologies Group, Inc., a Florida corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-1, Registration No. 333 - 268638 (such registration statement, as amended, is referred to as the “Registration Statement”), covering the offering for resale, on a delayed or continuous basis, of (i) 902,002 shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), to be sold by the selling stockholders named in the Registration Statement (the “Selling Stockholders”, and such shares, the “Common Shares”); and (ii) 433,000 shares of Common Stock to be sold by the Selling Stockholders, issuable upon conversion of shares of Series D Convertible Preferred Stock, par value $0.001 per share (the “Series D Preferred Stock” and such shares of Common Stock that may be issued upon conversion thereof, the “Conversion Shares”).

The Common Shares and shares of Series D Preferred Stock were issued pursuant to Securities Purchase Agreements, dated as of September 30, 2022 and October 29, 2022 (the “Securities Purchase Agreements”), between the Company and the Selling Stockholders. This opinion is being rendered in connection with the filing of the Registration Statement. All capitalized terms used herein and not otherwise defined shall have the respective meanings given to them in the Registration Statement.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement as filed with the Commission on December 1, 2022, under the Securities Act of 1933, as amended (the “Securities Act”); (ii) the Registration Statement as filed with the Commission on December 29, 2022, under the Securities Act; (iii) the Amended and Restated Articles of Incorporation of the Company, as amended, as currently in effect; (iv) the Amended and Restated By-Laws of the Company, as amended, as currently in effect; and (v) certain resolutions and minutes of meetings of the Board of Directors of the Company relating to the Registration Statement, the Common Shares, the Series D Preferred Stock, the Securities Purchase Agreements and the transactions contemplated thereby. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinion set forth herein.

In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified, conformed or photostatic copies, and the authenticity of the originals of such copies. In making our examination of executed documents, we have assumed that the parties thereto, other than the Company, had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. As to any facts material to the opinion expressed herein which we have not independently established or verified, we have relied upon statements and representations of officers and other representatives of the Company and others.
