We should make a difference between "physically impossible" and "physically possible but legally forbidden". This is important for a series of situations, e.g. an emergency car in action could cross a road marking without problems (paying attention to surrounding traffic), while if would still be physically impossible to cross a concrete or steel barrier. Ideally our data would allow to extract this information.
An emergency vehicle could also cross a grass median if there's no raised barrier.
