Which statement describes an object marker sign?

• A. a barricade at a work zone
• B. an object marker on a roadway
• C. a warning sign at a work zone
• D. a guide sign on an interstate highway

Answer: (D)

Object marker signs are placed to identify fixed objects in or near the roadway so drivers know there’s an obstacle ahead and can steer safely away. They mark things like guardrails, culverts, or bridge ends and are meant to give advance warning about the exact location of a hazard on or beside the road. This is distinct from barricades (temporary barriers), warning signs at work zones (alerting you to construction conditions), or guide signs on interstates (providing route information). So describing an object marker sign as marking a fixed object on the roadway best captures its purpose.
