EMS and Pittsburgh Police officers from Zone 4 responded to reports of a male driver in possible distress on 5th Avenue at N. Craig street just before 5:15 p.m.
When they arrived on scene witnesses directed them to a vehicle with a male driver who had suffered some type of medical episode while driving.
Witnesses say the man was driving so slowly through the intersection that they were able to help bring the car to a stop so it was resting partially on the sidewalk.
The vehicle did not hit anything.
The man was transported by EMS in critical condition.
