Which type of transportation is excluded from the Texas Private Security Act based on Chapter 1702.325?

The Texas Private Security Act, specifically referenced in Chapter 1702.325, provides stipulations regarding the types of transportation that are regulated under the act. The exclusion for certain types of transportation focuses on the nature of the service and its regulation by other governing bodies.

Common carriers by rail are not included in the definitions covered by the act, as railway transport falls under distinct federal and state regulations that govern the railway industry, separate from private security services. This ensures that transportation by rail, which is crucial for the movement of goods and people, is managed under its own specific regulatory framework, allowing for streamlined oversight without overlap from private security regulations.

In contrast, the other options pertain to types of transportation that may involve varying degrees of direct oversight under the Private Security Act, particularly private transportation services and air freight, which may intersect with security needs and concerns in their operations. Therefore, it is the specificity of railway operations and their regulatory environment that leads to the exclusion of common carriers by rail from the Texas Private Security Act.
