The safety of the traveling public is a major priority in the location of the historical marker itself. The markers are not mounted on breakaway supports and have not been tested for vehicle impacts; therefore, they are to be considered non-breakaway. They should be located outside the clear zone or protected or not installed at all.

TxDOT policy specifies that markers be located in roadside parks, at existing turnouts, or at a specially prepared turnout. The primary effort in locating these markers should be to utilize existing facilities. Where such cannot be done, locations should be selected that would require a minimum amount of improvement. In these instances, the usage by the public should determine the extent of development necessary. Often soil conditions will require only minor grading or a minimum amount of stabilization. Surfacing will be justified for very few marker facilities. TxDOT strives to cooperate with the historical marker program by placing markers in locations accessible to the public. Nevertheless, the scope of the program is such that the economic aspects deserve careful attention.

Marker placement can be discussed with the county historical commission.
