Persistent low water levels in the Rhine are forcing some companies to cut production, slowing the economy in Germany.

A complete shift of deliveries to road transport is hardly possible, according to industry sources.

Because of persistent low water on the Rhine and other rivers, additional German states are suspending the Sunday and public holiday driving ban for trucks.

German Federal Transport Minister Bilger wants to discuss further measures with the federal states' department heads tomorrow.

Markus Wolf, State Secretary at the Transport Ministry of the German state of Rhineland-Palatinate, said: "We must counteract and have done so by lifting the Sunday driving ban."
