Emergency services are currently responding to a significant collision involving approximately 15 vehicles on the M23 near Gatwick Airport. The incident, which occurred around 5:40 pm this afternoon, has led to the closure of the motorway between Junctions 10 and 11, with traffic being diverted as recovery and rescue operations are underway.

Reports indicate that multiple casualties are being treated at the scene, with ambulance crews assessing and providing medical aid to those injured. An air ambulance has also been dispatched to assist in the response efforts.

Eyewitnesses described the scene as chaotic and distressing, with vehicles scattered across the carriageway and significant damage visible. Roger Williams, who witnessed the aftermath of the collision, described it as the “worst pile up” he has seen in over six decades, noting overturned vehicles and debris strewn across the road.

It is reported that a hail storm occurred in the area around the time of the collision, potentially contributing to hazardous road conditions.
