Trucks can significantly reduce carbon dioxide emissions when used on e-highways. This is shown by the first results of the Schleswig-Holstein pilot test on the route between Lübeck and Reinfeld.

Criticism, however, comes from the Taxpayers' Association. The field trial will run until the end of 2024 and is funded by the Federal Ministry for Economic Affairs and Climate Protection. It is one of three pilot projects in Germany in which the use of overhead line trucks in real operation is being researched.
