Moon, who was testifying for the second day in the Randburg Magistrate’s Court yesterday, said he could not avoid driving into Ncube, who later died from her injuries in July 2009.
Ncube was walking with her cousin Thandi Sibanda at the time of the accident.
Moon – who was accompanied to court by his parents Patrick and Geraldine Moon – said when he saw the two women on the road he swerved to the right and applied brakes within seconds – but could do nothing more to avoid hitting Ncube.
Moon is alleged to have been speeding at the time of the accident.
Defence witness Wilna Badenhorst, an accident reconstruction expert, testified that she could not say at what speed Moon’s car had been travelling, because no physical evidence was recorded to enable her to calculate the actual speed at which the car had been moving.
Said Badenhorst: “The injuries sustained give an idea how the pedestrian was positioned.”
She criticised the state’s accident expert, who had testified that human error was a contributing factor to the accident.
“This is not a fair and accurate way to calculate the critical speed that a vehicle is travelling in,” she said.
Moon was also criticised by the state’s accident expert of negligent driving.
