    Report summary

    On 31 January 2017, Darren Richard Trewin was fatally injured when the car he was driving left the A30 after encountering water flowing across the carriageway from a partially blocked drain and collided with a roadside barrier. Concerns related to the drain’s ability to capture heavy rainfall and the possible need to extend the nearside barrier to reduce the risk of vehicles leaving the carriageway.

    How this individual concern was interpreted

    PFD Monitor created a concise, searchable interpretation from the report wording shown below. The report was sent to Devon Highways; that does not assign responsibility.

    PFD Monitor interpretation

    Inadequate carriageway drainage capacity for heavy rain

    Wider context from the report

    “(1) The drain in the central reservation was partially blocked with detritus washed from the road. The drain therefore could not take all the water from the heavy rain showers resulting in the water cascading across the carriageway contributing to the collision. Highways engineers who attended the Inquest were of the view that the grating on the drain should be changed to capture more water and the drains inspected more frequently and an additional drain, located above the drain that blocked should be created to assist with the capture of excess water from heavy rain. ”

    PFD Monitor interpretation

    Insufficient nearside barrier length beside a carriageway drop-off

    Wider context from the report

    “(2) To consider extending the barrier on the nearside of the carriageway to a point before the point of impact would possibly have prevented Mr Trewin’s car from leaving the carriageway and entering the woods. A longer barrier at this point, where the ground drops away to a much lower level below the carriageway, could improve safety for all drivers using the A30 at this point. ”
