Four people were injured, two of them critically, in a crash Monday afternoon on the South Side.

The man who was driving the Passat and a woman who was riding with him were both taken to University of Chicago Medical Center in critical condition, police said.

The pedestrian and the Challenger’s male driver were taken to Christ Medical Center in Oak Lawn, police said. Both their conditions were stabilized.
