(a) Except as provided in § 61.022 of this code, this subchapter does not limit the power of an incorporated city, town, or village bordering on the Gulf of Mexico or any adjacent body of water to regulate motor vehicle traffic and prohibit littering on any beach within its corporate limits.
(b) If these regulatory ordinances are adopted by a city, town, or village and the ordinance conflicts with the general law of the state or with an order of the commissioners court adopted under this subchapter, and the ordinance is consistent with policies and rules under § 61.011 of this code, the ordinance shall control over the state law and the order, and in cases of violation, prosecution may be maintained only under the ordinance.
