The driver and her passenger allegedly fled the scene on foot and are being sought by police.
Bendolene Stuurman and Johanna Beukes sustained several injuries when they were hit by a white Chevrolet which flipped onto the pavement in Springbok Road in Kleinvlei shortly after 4pm on Sunday.
The two mothers are activists for the DA and were volunteering at voter registration centres over the weekend.
DA Metro chairperson, Grant Twigg, says he was called to the site shortly after the incident and found the two women being treated by paramedics.
“They were standing at a table on the corner of Impala and Springbok streets and, according to the witnesses, the car came speeding down the road and hit a big rock and went straight towards them,” Twigg explains.
“The car also flipped as it hit the pavement and the two activists were injured.”
Twigg says the car was allegedly driven by a women with a male passenger and both occupants fled the scene.
“The witnesses say the owner of the car was drunk and so the woman was driving. Both injured women are in their 40s and are mothers. I visited them at Tygerberg Hospital where they are recovering.
“On Sunday when I saw them they were waiting for the results of their scans and both of them are in neck braces, but they were both conscious.”
Police spokesperson, Captain FC van Wyk, confirmed the incident and says a case of reckless and negligent driving is being investigated.
