Heavy machinery transport permits are official authorisations issued by road or highway authorities whenever a vehicle combination exceeds the statutory limits for gross weight, axle load, width, length, or height. Without a valid permit, the movement is illegal regardless of how securely the load is fastened—a point enforcement officers check at roadside. The permit specifies the approved route, permitted travel windows (often restricted to daylight hours or certain weekdays), requirements for pilot vehicles or police escorts, and any advance structural checks of bridges or overhead obstacles. Cross-border movements require a separate permit for each country transited, making early application essential. Carriers that breach permit conditions face substantial fines, liability for damage to road infrastructure, and immediate stoppage of the transport.
