Where:
On any tarred (paved) road, especially in rural or farming areas where the road transitions from a sealed surface to a gravel or dirt surface.

Purpose:
To warn motorists that the smooth, tarred section of the road will soon end and that a gravel, dirt, or unpaved road surface lies ahead.
This change in road condition can affect vehicle handling, traction, and braking ability, increasing the risk of skidding or losing control if the driver is unprepared.

Action:
Reduce your speed well before reaching the end of the tarred surface.
Be alert for uneven sections, ditches, or potholes where the two surfaces meet, as these can cause a sudden jolt or loss of traction.
Once on the gravel section, steer gently and avoid sudden acceleration, braking, or sharp turns. Remember that vehicles tend to slide more easily on loose gravel and require a longer distance to come to a complete stop.
Maintain a firm grip on the steering wheel and drive cautiously, especially if visibility is reduced or if other vehicles are creating dust clouds.
