Where must the Slow Moving Vehicle (SMV) placard be located on a crane?

The Slow Moving Vehicle (SMV) placard is specifically designed to alert other drivers that the vehicle is moving at slower speeds and to promote safety on roadways. When it comes to cranes and similar equipment, the correct placement of the SMV placard is at the rear of the equipment. This position is crucial because it ensures maximum visibility to drivers approaching from behind, allowing them to react appropriately and maintain a safe distance.

In the case of cranes, which can be quite large and may have limited speed capabilities when being moved on public roads, having the placard clearly visible from the rear helps prevent accidents and enhances overall safety. This placement is not just a suggestion but is often mandated by safety regulations governing the operation of such vehicles on public roads.

Other options, such as positioning the placard on the front windshield or on the left side of the crane, do not meet the visibility requirements necessary for effective warning to other motorists. Similarly, placing the placard under the operator's seat would render it invisible to anyone outside the crane, negating its purpose entirely. Therefore, the rear location of the SMV placard is the most logical and effective choice for safety compliance.
