Patrick Anthony MONGAN · Prevention of Future Deaths report

On 20 September 2024 I commenced an investigation into the death of Patrick Anthony MONGAN. The investigation concluded at the end of the inquest . The conclusion of the inquest was Road Traffic Collision.

The cause of death was:

1a Chest injuries

1b Road Traffic Collision

This relates to the death of an 18 year old male who died following an RTC on the 7th September 2024. The circumstances surrounding the death are as follows;

At 02:26 hours, South Yorkshire Police received a report of a RTC on the Northbound carriageway of the M18 between junctions 1 & 2 where it was reported that a vehicle had left the carriageway to the nearside disappearing into trees. Staff from Highways England arrive on scene and locate the vehicle embedded deep into the trees and two males, Patrick Mongan (DOB 21/03/2006) and his brother, had been ejected from the vehicle landing next to it. Patrick Mongan, was reported to not be breathing and life was pronounced as extinct at 03:10 hours. It was later identified that the subject vehicle had struck a grassed mound of earth on the central reservation which interrupted the tarmac construction of the central reservation causing the vehicle in which the deceased was a passenger to become airborne.

The Forensic Collision Investigator advised that the aforementioned mound of earth creates a continuing hazard to motorway users and any vehicle which might have legitimate cause to veer to the central reservation and in doing so strikes the mound, even when travelling within the speed limit, would be subjected to the same effect on the vehicle (in that control of the vehicle would be lost) with potentially catastrophic effects. The continued presence of this hazard (the mound of earth on a tarmac construction) places road users at risk of death
