The matter will resume on April 3 to allow his newly appointed lawyer Thomas Mahlobogoane time to obtain the court records and get a pre-sentencing agreement form.
Mahlobogoane told the court he had written to the court clerk on January 27, requesting the records, but had not received any response.
Semitjie, former driver of then Gauteng housing MEC Humphrey Mmemezi, was convicted of reckless and negligent driving on December 3.
He was driving Mmemezi to a meeting when he crashed into biker Thomas Ferreira in 2011.
During the trial, it was heard that Semitjie was driving on the left side of the yellow lane, had not put on his siren, and skipped a red traffic light.
Ferreira, who was 18 years old at the time, suffered head injuries and was comatose for weeks.
Delivering judgment in December, Magistrate Abdul Khan criticised Semitjie for not offering any assistance to Ferreira, even though he had not suffered any visible injuries.
