What actions must be taken with a lowered bucket before traveling on a road?

Before traveling on a road, it is crucial to raise and secure the bucket of the excavator according to the manufacturer's guidance. This practice is essential for several reasons.

First, raising the bucket minimizes the risk of striking overhead obstacles such as trees, power lines, or bridges, which could cause accidents or damage both to the equipment and surrounding infrastructure. A lowered bucket can also pose a threat to low-lying objects and pedestrians, increasing vulnerability to accidents.

Second, securing the bucket in a raised position provides a clearer line of sight for both the operator and other road users, enhancing safety during transportation. When the bucket is elevated properly, it does not obstruct visibility, allowing for better awareness of the surroundings.

Moreover, following the manufacturer's guidelines ensures that the equipment operates within designed safety parameters, reducing the likelihood of mechanical failure while traveling. Manufacturers design their equipment with specific operational protocols to maximize safety and efficiency.

The other options, although they may seem practical in certain contexts, do not align with recognized safety practices when it comes to traveling on public roads or areas where pedestrian traffic may be present.
