A coroner has called for improved road markings and signage on an M62 slip road where a man in his early 20s died in December last year.

Mason Portman, from Bradford, died after he lost control of the car he was driving as he exited the slip road at junction 22 on the eastbound carriageway to the M62.

The car then crashed into a wooden fence and road sign, before it travelled across the moorland and towards the A672 Oldham Road, where it crashed into a parked and unoccupied car on the layby.  It then tumbled across the A672 and came to rest.

The crash caused Mr Portman, 21, to suffer fatal injuries, and a post-mortem examination found he was significantly over the drink-drive limit and had cocaine in his system.

Following an inquest into Mr Portman's death, which concluded on August 13 at West Yorkshire (Western) Coroners Court, a coroner has called for appropriate road markings and signage to be placed on the slip exit and for the safety of the road to be reviewed.

West Yorkshire senior coroner Martin Fleming wrote in a Prevention of Future Deaths Report to National Highways: "During the inquest I heard that as Mason approached the location of the collision via the slip road that there were no road markings or signs displayed to advise on appropriate speed or road curvature ahead."

Mr Fleming said he feels that action needs to be taken to prevent future deaths at the site.

Following the inquest into Mr Portman's death, Mr Fleming ruled that Mr Portman's cause of death was "multiple injuries" due to a "road traffic collision".

A spokesperson for National Highways said: “Our deepest sympathies are with the family and friends of Mason Portman, and everyone affected by this incident.

“We are committed to continuing to make our roads as safe as possible. We will review the Coroner’s comments and provide a comprehensive response to the Coroner’s report.”
