System, methods, and other embodiments described herein relate to dynamically determining an appropriate responsive action for a moving vehicle in accordance with local traffic regulations. In one embodiment, the disclosed system identifies a stationary vehicle in an environment of the subject vehicle based at least in part on information from a plurality of sensors disposed on the subject vehicle and classifies a type of the stationary vehicle as valid or abandoned based at least in part on the information from the plurality of sensors. A classification of valid indicates that a traffic regulation requires the subject vehicle to undertake a responsive action toward the stationary vehicle. The disclosed system obtains a local traffic regulation based on a location of the subject vehicle and modifies a trajectory of the subject vehicle based on the local traffic regulation when the type of the stationary vehicle is determined to be valid.
