What indicates a bus stop on the roadway?

Answer: A — specific sign or painted marking

A specific sign or painted marking clearly indicates a bus stop on the roadway. These signs serve a critical purpose, informing drivers and passengers alike about where buses are designated to stop for loading and unloading. The presence of these indications helps ensure safety by alerting motorists to be cautious and watch for pedestrians and cyclists, especially during pick-up and drop-off times. Other options, while they may relate to driving or public transport, do not serve the specific purpose of marking a bus stop. A traffic light that blinks could signal various actions or alerts but does not specifically indicate a bus stopping point. Similarly, a yellow speed limit sign provides important information about speed regulations but has no connection to where buses may stop. An auditory announcement may inform passengers about bus arrivals or stops but does not denote a physical location on the roadway for a bus stop. Thus, only a specific sign or painted marking fulfills the requirement for indicating a bus stop.
