Where:
On any road, particularly before tunnels, bridges, overhead passes, or other structures with limited vertical clearance.

Purpose:
To warn drivers that there is a structure ahead with a height restriction, as indicated on the road traffic sign.
This ensures that vehicles exceeding the specified height do not attempt to pass underneath and cause damage to the structure or the vehicle.

Action:
Before reaching the structure, check your vehicle’s height, including any loads, roof racks, or mounted equipment, and compare it with the restriction shown on the sign.
If your vehicle is higher than the indicated clearance, do not proceed.
Stop safely and plan or follow an alternative route suitable for your vehicle’s height.
