Cape Town - The SA National Roads Agency Limited (Sanral) is sitting with over 1.4 million unsold e-tags, according to Transport Minister Dipuo Peters.
"Sanral procured 2 107 000 e-tags over the past three years; [a total of] 1 427 900 have not been allocated," she said in a written reply to a parliamentary question.
The figures imply 679 100 e-tags have been sold.
Six weeks ago, Sanral CEO Nazir Ali said 600 000 e-toll tags were in circulation.
In September, President Jacob Zuma signed into law the transport laws and related matters amendment bill, giving Sanral the nod to start e-tolling on Gauteng's freeways.
In her reply, Peters said Sanral had spent about R25.3m during the period January to October this year on campaigns to encourage the public to buy e-tags.
This was in addition to about R11.3m spent in November and December last year.
