Final answer:
A security guard misrepresenting his/her license violates the Private Security and Investigative Services Act, which may lead to legal penalties such as fines or losing the license.
Step-by-step explanation:
A security guard who misrepresents his/her license is indeed in violation of the Private Security and Investigative Services Act. Misrepresentation may include providing false information, altering details on a license, or using an expired or invalid license to perform duties. Such actions are contrary to the regulations that govern the licensing and conduct of private security personnel. Adherence to the Private Security and Investigative Services Act is crucial in maintaining professional standards and ensuring the trust of the public in the security services sector. Misrepresentation not only compromises personal integrity but can also lead to legal consequences like fines, license suspension, or revocation for the individual involved.
