Four occupants of a Toyota Corolla were injured in a crash on the N7, just past Vissershok Road, in the direction of Malmesbury.
When paramedics arrived on the scene they found the crumpled Toyota Corolla up against a sign post. One patient, who sustained serious injuries, was still inside the vehicle and needed to be extricated by medical crews.
Another three patients were already outside the vehicle and treated for minor to moderate injuries. All four patients were transported to Tygerberg Hospital.
The cause of the crash is unknown.
