In the TV debate with Peer Steinbrück on 1 September 2013, Chancellor Angela Merkel said: Mit mir wird es keine PKW-Maut geben! With me there will be no car toll. On 27 November 2013, the CDU, CSU and SPD agreed in their coalition agreement to introduce one. On 27 March 2015, the Bundestag passed it. That day the SPD member Lothar Binding explained in a written statement why he voted yes. Fair dealing with agreements, including coalition agreements, required it. He added: Deshalb wird mit Angela Merkel heute die PKW-Maut in Deutschland eingeführt. That is why the car toll is introduced in Germany today, with Angela Merkel.
The spoken promise gave way. The signed agreement held.
