Marker posts on the road are positioned every how many meters?

Answer: B — 100m

Marker posts on the road are strategically placed to assist with navigation and to provide important information to drivers, especially in emergency response situations. The standard distance between these posts is typically 100 meters. This interval ensures that they are visible and recognizable, helping drivers maintain awareness of their location and the surrounding environment. Such markers can be vital in emergencies where quick identification of location is necessary for effective coordination and response. The choice of 100 meters strikes a balance between visibility and practicality for emergency vehicles, allowing for reliable tracking of distance while traveling.
