Common types of oversize loads include:
- Construction equipment (cranes, excavators, bulldozers)
- Industrial equipment and machinery
- Wind turbine components (blades, towers)
- Large vessels or tanks
- Prefabricated building sections
- Bridge beams
- Mobile homes
Special requirements usually include:
- Warning signs ("OVERSIZE LOAD" or "WIDE LOAD")
- Flashing lights or beacons
- Pilot/escort vehicles (also called pilot cars)
- Special route planning to avoid low bridges, narrow roads, or weight-restricted areas
- Transportation during specific times (often night hours or off-peak)
- Special permits from state/provincial authorities
- Trained and specially licensed drivers
Dimensional considerations that make a load "oversize":
- Width exceeding standard lane width (typically over 8.5 feet/2.6 meters)
- Height exceeding standard clearances (typically over 13.5 feet/4.1 meters)
- Length beyond standard trailer limits
- Weight exceeding standard road limits
Safety measures often include:
- Route surveys before transport
- Police escorts for extremely large loads
- Advance notification to utilities and local authorities
- Temporary removal of road signs or traffic signals if needed
- Special weather monitoring and contingency planning
