Final answer:
Object markers are reflective indicators placed close to the edge of the roadways, serving as a warning for drivers about objects or hazards that are not in the roadway. They help improve road safety by alerting drivers to potential dangers near the edge.
Step-by-step explanation:
The object marker you are referring to is most commonly found on roadsides and highways. These markers are usually reflective and are placed close to the edge to warn drivers of objects or hazards that are not in the roadway but may still pose a risk.
For example, if there's a deep ditch or a steep slope on the side of the road, these markers serve as a visible indicator to drivers, reminding them to stay away from the edge and maintain a safe distance.
While the specific design or appearance of these object markers can vary, their purpose remains the same - to improve road safety by alerting drivers to potential dangers near the edge of the roadway.
