A coroner has demanded Transport for London do an "urgent review" of the blue paint used on cycle superhighways after a motorcyclist died earlier this month.

Milan Dokic, 49, crashed on March 1 after losing control of his motorbike in wet conditions.

As a result, coroner Dr Fiona Wilcox has issued TfL with a prevention of death report after deeming the surfaces unsafe.

Dr Wilcox is only in the pre-inquest review stages but said the concerns are "too urgent to wait until the full hearing of the evidence to be addressed" as lives could be at risk.

In the report she said: "During the course of the pre-inquest review the preliminary evidence revealed matters giving rise to concern.

"In my opinion there is risk that future deaths will occur unless action is taken."

Based on CCTV recordings, Mr Dokic was travelling east on his motorbike and overtaking a van when he drove onto the blue cycle lane just past the pedestrian crossing opposite the junction with Forfar Road. He lost control, hit a bollard and died from related injuries.

During the course of the pre-inquest review the preliminary evidence revealed matters giving rise to concern.

The coroner also said the lack of grip on the surfaces "may be widespread".

She added: “TfL should therefore undertake an urgent review of all areas treated with such road surface and replace it with the higher group surface

"That the CSH should all have increased rather than reduced grip compared to the ordinary road surface since cyclists are vulnerable road users.

"That areas of road at junctions such as this junction between Battersea Park Road and Forfar Road are of particular concern from a risk perspective.

"That these concerns are too urgent to wait until the full hearing of the evidence to be addressed.”

In response to the fatal incident and subsequent report, Leon Daniels, TfL’s managing director of Surface Transport, said: “Our thoughts are with the family and friends of Milan Dokic.

"We’re preparing our response to the Coroner and carefully considering the issues raised.

"We are confident our cycle superhighway network is improving the safety of London’s roads.

"We are working hard to tackle the dangers on London's streets.

"We are investing in safer cycle lanes and junctions, working with boroughs to introduce more 20mph limits, removing the most dangerous Heavy Goods Vehicles from the Capital and continuing our road safety education and enforcement programmes."
