70.— (1) Where in proceedings for an offence under section 68(15) relating to any alleged contravention of any requirement or prohibition imposed under reduced mobility regulations, being a provision for which there is a code of practice published at the time of the alleged contravention, subsection (2) has effect with respect to that code of practice in relation to those proceedings.

(2) (a) Where a code of practice referred to in subsection (1) appears to the court to give practical guidance as to the observance of the requirement or prohibition alleged to have been contravened, the code of practice is admissible in evidence.

(b) Where it is proved that any act or omission of the defendant alleged to constitute the contravention—

(i) is a failure to observe a code of practice referred to in subsection (1), or
