Last week, the mayor revealed that he intended to remove the most dangerous lorries from the capital by 2020 in a bid to make roads safer for pedestrians and cyclists.

However, the MPA has now alleged that these plans could negatively impact both road safety and the ability to deliver new homes and infrastructure in London.

Nigel Jackson, chief executive of the MPA, said: “MPA members are absolutely committed to improving road safety for all vulnerable road users.

“This is not just talk, our industry has taken very significant practical action and invested heavily in training and technology.

“[However,] there seems to be no recognition of the link between any vision for London and the practicalities of how we are going to make that happen and the vital role transport must play in delivering that vision on the ground.”

In 2012, Transport for London (TfL) commissioned a Construction Logistics and Cyclist Safety (CLOCS) review of the construction sector’s transport activities in order to understand the causes of cyclist fatalities.

The CLOCS initiative has seen the construction supply chain take sustained action to train drivers and equip HGVs with additional safety equipment such as cameras and sensors.

The scheme has also improved the planning of deliveries to sites in order to reduce collisions between industry vehicles and vulnerable road users.

Nigel insisted that the MPA had been leading supporters of the CLOCS initiative from the outset.

However, the mayor has now suggested that by using TfL’s Direct Vision Standard – based on the level of vision a driver has directly from their cab – only HGVs with a rating of three out of five or above will be allowed on London’s roads by 2024.

MPA alleged that this new vision-rating system was not as effective at preventing blind spots as the technology that had been introduced under CLOCS.

The Association claimed that banning 35,000 HGVs would make it difficult to supply the needs of London’s housing and infrastructure developments.

Nigel added: “We hope that the mayor takes note of the concerns of our sector, which supplies the greatest tonnages of essential products to the construction industry in the capital, and he agrees to engage with the industry as a matter of some urgency.”

The mayor’s office has been contacted for comment.
