If the site below is to be believed, 14-298 applies to the State Traffic Commission and what they are empowered to do. It does not govern what a motorist can or can not do, so it doesn't apply to you.
14-298 is what they are using to charge you. If it's incorrect, it's too late for them to fix it, so you should be able to get it tossed on the grounds that it doesn't apply to you.
