This isn't an accident or a breakdown, it's someone who thinks it's OK to stop in the middle of a busy road frequently used by ambulances going to and from the nearby hospital so they and their passenger can have a chat with somebody parked at the side of the road. Misuse of hazard lights, facing on-coming traffic and blocking the highway.
Driven by some impatient yob around Gleadless in Sheffield. Always seems to be in a hurry, despite I imagine him having nowhere especially to get to. Steer well clear to avoid either being driven over or having him hurl unnecessary insults at you whilst you driving normally.
This driver frequently uses the wrong lane to take required exit in an attempt to beat traffic, only to be caught up again 600 yards down the road.
