On 1 September 1951, East Germany, because of a shortage in foreign currencies, started to levy road tolls on cars using the transit routes. At first, the toll amounted to 10 Ostmark per passenger car and 10 to 50 for trucks, depending on size.[citation needed] Ostmarks had to be exchanged into Deutsche Mark at a rate of 1:1. On 30 March 1955, East Germany raised the toll for passenger cars to 30 Deutsche Marks, but after West German protests, in June of the same year, it changed it back to the previous rate.[citation needed]
