Where:
On any public road where one or more driveways or side roads join the main road in such a way that they are difficult to see.
This may be due to hedges, walls, buildings, bends in the road, or other visual obstructions that block a clear view of vehicles entering or exiting the driveway.
The sign can indicate a concealed driveway on the left, right, or both sides of the road.

Purpose:
To warn drivers that vehicles may unexpectedly enter the road from a concealed driveway.
Because visibility is limited, both you and the driver of the vehicle entering from the driveway may have difficulty seeing each other.
The sign helps reduce the risk of collisions by encouraging caution and slower speeds.

Action:
Reduce speed when approaching the area to allow enough time to react to vehicles entering or exiting the driveway.
Be prepared to stop or yield if a vehicle suddenly emerges from the concealed driveway.
Stay alert for cross traffic, pedestrians, or cyclists who may also be using the driveway.
Increase your following distance from vehicles ahead so you have more reaction time if they stop suddenly.
Check blind spots carefully if you plan to overtake near a concealed driveway, as entering vehicles may appear unexpectedly.
Be aware that drivers exiting the driveway may also have limited visibility and may enter your path without seeing you clearly.
Drive defensively, anticipating the possibility of sudden movements from vehicles joining your road from the concealed driveway.
