20-49.2. Supplemental authority of State Highway Patrol Motor Carrier Enforcement officers.
In addition to law enforcement authority granted in G.S. 20-49 or elsewhere, all sworn Motor Carrier Enforcement officers of the State Highway Patrol shall have the authority to enforce criminal laws under the following circumstances:
(1) When they have probable cause to believe that a person has committed a criminal act in their presence and at the time of the violation they are engaged in the enforcement of laws otherwise within their jurisdiction.
(2) When they are asked to provide temporary assistance by the head of a State or local law enforcement agency or his designee and the request is within the scope of the agency's subject matter jurisdiction.
While acting pursuant to this section, they shall have the same powers invested in law enforcement officers by statute or common law. When acting pursuant to subdivision (2) of this section, they shall not be considered an officer, employee, or agent for the State or local law enforcement agency or designee asking for temporary assistance. Nothing in this statute shall be construed to expand their authority to initiate or conduct an independent investigation into violations of criminal laws outside the scope of their subject matter or territorial jurisdiction.
