Where:
On any road, but most commonly found in mountainous areas, narrow passes, or routes with sharp bends, tunnels, or confined spaces.

Purpose:
To warn that the curves, gradients, or structures along the road make it unsafe or impossible for vehicles longer than the length indicated on the road sign to pass through safely.
This restriction helps prevent long vehicles from becoming stuck, blocking traffic, or causing accidents in tight or winding areas.

Action:
Before proceeding, check your vehicle’s total length, including any trailers or attachments.
If your vehicle exceeds the length shown in metres on the sign, do not continue along that route.
Instead, find an alternative road that can safely accommodate your vehicles size.
Always plan your route ahead of time if you are driving an unusually long vehicle.
