This report repeats 3 earlier warnings. See the linked reports.
The coroner's concerns
1. standing water causing hydroplaning
“The centralised location of these collisions suggests that there may be ongoing issues with drainage on this section of the road”
2. insufficient trigger for drainage renewals
“The trigger for "renewals" appears to be narrow and restricted to "recorded flood events" and does not for instance include recorded instances of collisions due to hydroplaning”
3. lack of drainage surveys and works
“Despite this fatal collision having occurred in December 2025, the topographic and drainage surveys are not yet available and no works other than "minor works for overburden removal" have taken place”

“The scene of the collision is in a natural 'bowl' and that, unless effectively drained, it is a point at which standing water will accumulate during and/or after heavy rainfall”

Earlier report
“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.”

Earlier report
“(2) Whilst the precise cause of the flooding is unknown, a more regular maintenance schedule may have prevented the buildup of vegetation within the gullies and therefore assisted in the drainage of the heavy rainfall experienced that day thus reducing the amount of surface water present on the road”
