Code of Federal Regulations Title 28. Judicial Administration § 28.29.12 Specified conditions under which stops may be authorized

(a) Time. A motor vehicle owner may authorize law enforcement officers to stop the enrolled vehicle if it is being operated between the hours of 1:00 AM and 5:00 AM. By enrolling in a program with this condition, the owner must state that the vehicle is not normally operated between the specified hours, and that the owner understands that the operation of the vehicle between those hours provides sufficient grounds for a law enforcement officer to reasonably believe that the vehicle is not being operated by or with the consent of the owner, even if the law enforcement official has no other basis for believing that the vehicle is being operated unlawfully.

(b) Border crossing or port entry. A motor vehicle owner may authorize law enforcement officers to stop the enrolled vehicle if it crosses, is about to cross or is about to be transported across a United States land border, or if it enters a United States port. For purposes of this section, the phrase “about to cross a United States land border” means the vehicle is operated or transported within one mile of a United States land border. Participating States or localities may implement this provision in accordance with local conditions, provided that a participating State or locality may not extend the applicable geographic area beyond one mile from the United States land border. By enrolling in a program with this condition, the owner must state that the vehicle is not normally driven across a border or into a port, and that the owner understands that the operation or transport of the vehicle within a mile of a United States land border or into a port provides sufficient grounds for a law enforcement officer to believe that the vehicle is not being operated by or with the consent of the owner even if the law enforcement officer has no other basis for believing that the vehicle is being operated unlawfully.
