Where:
On any road, especially on rural, gravel, or construction roads where road maintenance is taking place.

Purpose:
To warn drivers that a road grader, a large machine used to level, smooth, or maintain the road surface,is operating on the carriageway ahead.
The sign alerts drivers to possible hazards, changes in road conditions, and partial lane closures.

Action:
Reduce your speed and be prepared to slow down further or stop if necessary.
Drive carefully past the grader, keeping a safe distance from both the machine and its operator.
Expect that the full width of the road may not be available due to the graders presence.
Be aware that loose sand, gravel, or dirt may be on the road surface, which can affect vehicle handling and braking.
Avoid overtaking near the grader unless there is a safe and clearly visible space to do so.
Watch for other workers, machinery, or traffic controllers who may be present near the grader.
