Bicyclists are considered vehicle operators and, with certain exceptions, must obey the same laws as other traffic. They may ride on the shoulder or berm, but are not required to do so. They may also travel at less than the minimum posted speed limit without being cited for a traffic violation.
12 . A speed limit posted on a curve:
A posted speed on a curve may be safe to be driven when operating a straight truck or a single-trailer combination but unsafe to be driven in a double or triple.
