PFD Monitor interpretation

Failure of road drainage to prevent water running across the carriageway

Wider context from the report

“The M20, a dual lane motorway, at the location where the collision took place has had a number of collisions occur which appear to have been caused by water/aquaplaning. Investigating police from the Serious Collisions Investigation unit commented that they are aware that this location is a problem in heavy weather and have attended collisions at this location in the past. The crash location is at the bottom of an incline on the M20 motorway which normally would not cause an issue, however the road also has a camber which causes water to run across the carriageway rather than draining into either the central reservation of the drain on the hard shoulder. The police officer believes that it is when this heavy water is running across the carriageway that there is an issue which does require further investigation as to any remedial works that can be completed to prevent any further fatal/serious injury collisions. ”

Is this part of a recurring concern?

Yes — Inadequate drainage control of hazardous surface water on public routes; Inadequate road drainage allowing hazardous surface water to remain on carriageways.
