(a) The commissioners court of a county by order may regulate the sight distance for an intersection that involves a county road and that is located outside the limits of a municipality. The commissioners court may:
(1) define the appropriate sight distance;
(2) prohibit an obstruction of the sight distance by any vegetation, loose earth, or other item except a building or other structure affixed to the ground, if the obstruction is a traffic hazard; and
(3) provide for the removal and disposition of an obstruction maintained in violation of an order adopted under this section.
(b) The commissioners court may not adopt an order under this section that conflicts with an ordinance of a municipality located in the county or with a rule adopted by a state agency relating to billboards or outdoor advertising. An order adopted in violation of this subsection is void.
