This section relates to the supply of trailer registration information by the Secretary of State for Transport.
	Subsection (1) establishes a discretionary power for the Secretary of State for Transport to supply that information in accordance with subsections (3) to (8). Subsection (2) defines the meaning of "trailer registration information" as information held by the Secretary of State for Transport under Part 2 of the Haulage Permits and Trailer Registration Act 2018.
	Subsection (3) makes provision for trailer registration information to be supplied to the Secretary of State for the Home Department for one or more of the purposes listed in subparagraph (a) to (f). These are (a) immigration purposes; (b) the law enforcement purposes; (c) human welfare purposes; (d) purposes connected with the exercise of functions under the Proceeds of Crime Act 2002, (e) safeguarding national security; and (f) responding to an emergency.
	Subsection (4) makes provision for the trailer registration information being supplied to the Secretary of State by whom general customs functions are exercisable, for use in connection with those functions.
	Subsections (5) and (6) make provision for the trailer registration information being supplied to the NCA and HMRC respectively for use in connection with any of their functions.
	Subsection (7) makes provision for the trailer registration information being supplied to a "UK authorised person" and a "UK authorising officer" (limited to persons engaged in policing by subsections 36(3) and (4)) for use in connection with; (a) "specified purposes related to policing" (subsection 36(8) confers regulation making powers); (b) the law enforcement purposes; and (c) safeguarding national security.
	Subsection (8) makes provision for the trailer registration information being supplied to a "non-UK authorised person" and a "non-UK authorising officer" (limited to specified persons concerned with law enforcement, customs and immigration in Guernsey, Jersey, the Isle of Man and Gibraltar, by subsections 36(6) and (7)) for use in connection with; (a) the prevention, investigation, detection or prosecution of criminal offences or the execution of criminal penalties, including the safeguarding against and the prevention of threats to public security; and (b) purposes connected with the exercise of any statutory functions of the recipient relating to customs, excise, immigration or the proceeds of crime.
	Subsection (9) enables the Secretary of State to supply information received under subsection (3) to; (a) an immigration officer; (b) a designated customs official; and (c) the Border Security Commander, for use in connection with any of the purposes listed in subsection (3)(a) to (f). Subsection (10) operates in the same way so that information received by the Secretary of State under subsection (4) may be supplied by them to; (a) the Director of Border Revenue; and (b) a designated customs official, in connection with a customs function exercisable by that person. These ensure fluidity of information sharing within the Home Office.
	Subsection (11) is a saving provision that clarifies that, should the general customs functions exercisable by the Secretary of State for the Home Department under subsection (3) transfer to another Secretary of State, then the powers under subsection (3) should be read as the Secretary of State to whom those general customs functions are transferred.
