For how far out? A village near where I grew up had a low railroad overpass. The road underneath had been lowered to create clearance, but not very far on either side. The “low clearance” sign had the height at the overpass marked on it. While technically correct, it only “worked” for modest length straight trucks. The typical articulated truck spanned the depression. Geometry bites.
