What must you be aware of, if you want to transport the load?

You answered correctly. In Germany, when transporting a load, it must be properly secured so that it does not become a danger or fall off the vehicle. Additionally, the load must not cause avoidable noise, meaning steps must be taken to prevent rattling or other disturbances. However, loads are not generally allowed to have parts projecting to the side, as this could endanger other road users. So answers 1 and 2 are correct—secure the load and avoid unnecessary noise. This helps ensure safety and compliance with the German road traffic regulations.
