President Jacob Zuma's son, Duduzane, is expected to attend an inquest at the Randburg Magistrate's Court on Friday.
Duduzane Zuma allegedly hit a minibus taxi in Rivonia, Johannesburg, while driving a Porsche, causing the taxi to overturn.
One person was killed and three people were injured.
At the time, metro police spokesman Chief Superintendent Wayne Minnaar said the Porsche rear-ended the taxi on the M1 south off-ramp at Grayston Drive.
Last month, the NPA declined to prosecute Duduzane Zuma due to insufficient evidence.
It said the matter would be referred to a magistrate for a formal inquest, to determine whether the accident was caused by a human error.
Duduzane Zuma did not appear in court for the inquest on August 12.
The National Prosecuting Authority said it was disappointed by his failure to attend.
His legal representative informed the State that the president's son was not aware that he was supposed to be in court. - Sapa
