What must be shown on vehicles displaying the company name?

For vehicles displaying the company name in the context of the Texas DPS Private Security Bureau regulations, it is required that the company name is clearly visible and is presented in letters that are at least one inch high. This requirement ensures that the company name can be easily read and recognized by the public, which is important for accountability and transparency in security service operations. Having the company name prominently displayed helps in identifying the vehicle as part of the licensed security service and enhances public trust.

The size specification (one inch high) is critical because it provides a standard for visibility across different types of vehicles and at various viewing distances, maximizing the ability of the public and any regulatory authorities to see and identify the vehicle's ownership. This helps maintain professionalism and compliance with legal standards set forth by the Texas Private Security Bureau.

Options that suggest only the company's logo, the license plate number, or the owner’s name and contact information do not fulfill the specific regulatory requirement for the display of the company name in a standardized manner as outlined by the regulations.
