(a) Photo red light imaging detector equipment may be operated from a fixed pole, post, or other fixed structure on a state or county highway.

(b) Signs and other official traffic-control devices indicating that traffic signal laws are enforced by a photo red light imaging detector system shall be posted on major routes entering the area in question to provide, as far as practicable, notice to drivers of the existence and operation of the system.

(c) Proof of a violation of section 291C-32(c) shall be as evidenced by information obtained from the photo red light imaging detector system authorized pursuant to this chapter. A certificate, sworn to or affirmed by the reviewing police department, or a facsimile thereof, based upon inspection of photographs, microphotographs, video, or other recorded images produced by the system, shall be prima facie evidence of the facts contained therein. Any photograph, microphotograph, video, or other recorded image, produced by the system, that contains a clear and unobstructed image of a motor vehicle license plate shall be prima facie evidence that the motor vehicle to which the license plate is attached is the motor vehicle for which the license plate was issued. Any photographs, microphotographs, video, or other recorded images evidencing a violation shall be available for inspection in any proceeding to adjudicate the liability for that violation.

(d) The conditions specified in this section shall not apply when the information gathered is used for highway safety research or to issue warning citations not involving a fine or court appearance.
