(a) Free public use is required on roads eligible for construction and maintenance with Federal funds under this part. When required for public safety, fire prevention or suppression, or fish or game protection, or to prevent damage to unstable roadbed, the Commissioner may restrict the use of them or may close them to public use.

(b) The Commissioner shall conduct engineering and traffic analysis in accordance with established traffic engineering practices and determine the necessary maximum speed limit, maximum vehicular weight limit and other needed regulatory signs for roads which he maintains. The Commissioner shall make recommendations to local Government officials, who are authorized to enact and enforce ordinances on Indian lands, of his determination of the needed regulatory signs. Such regulatory signs as are authorized by established ordinances shall be erected by the Commissioner. At locations under the jurisdiction of the Court of Indian Offenses the Commissioner shall erect such regulatory signs as he determines are needed.
