Four people were seriously injured in an accident near Paarl on Saturday, Cape Town paramedics said.

ER24 spokesperson Tristan Wadeley said the accident occurred just before the Okavango Road turn off.

"It is alleged that an Uno travelling on the N1 towards Durbanville rolled across the middle island and hit an oncoming Toyota Tazz."

The four were occupants of the Uno. They were taken hospital for treatment, Wadeley said.
