A 3-metre wide construction machine is to be transported on public roads. Under which conditions may you perform the transport?

The selected conditions for transporting a 3-metre wide construction machine are essential to ensure safety and compliance with regulations.

1. **Labeling the Load**: This is important because it alerts other road users to the presence of a wide load, reducing the risk of accidents and helping to manage traffic flow.

2. **Permit from Competent Authority**: Obtaining a permit is crucial as it ensures that the transport complies with local road regulations and safety standards. The authority assesses the route, the vehicle used, and any potential hazards to ensure proper safety measures are in place during the transport.

Both these steps, according to German traffic rules, are necessary for the safe transport of oversized loads, ensuring that both the transport vehicle and other road users are adequately protected. The third option, stating that the load need not be labelled, was incorrect because it contradicts the safety measures required for such wide transports.
