What is CLOCS

Over 5,500 vulnerable road users are killed or injured every year in collisions on Britain’s roads with vehicles commonplace in construction – that’s 20 people every working day. 

CLOCS is a national Standard that requires all stakeholders in construction to take responsibility for health & safety beyond the hoardings. It demands collaborative action to prevent fatal or serious collisions between vehicles servicing construction projects and vulnerable road users: pedestrians, cyclists, and motorcyclists.


The CLOCS Standard requires action from clients, principal contractors and vehicle operators, and harnesses the power of policy-makers to minimise the impact of construction projects and eliminate harm to communities.

CLOCS  - ensures the safest construction vehicle journeys

  • zero collisions between construction vehicles and the community
  • improved air quality and reduced emissions
  • fewer vehicle journeys
  • reduced reputational risk

Why get involved?

Victoria Lebrec, RoadPeace spokesperson and casualty of a construction lorry crash, says “In 2014 my life changed forever when I was hit by a tipper truck whilst cycling in London. I lost my leg in the collision, and have had over 12 operations and months of physiotherapy. I urge all construction companies to join up to CLOCS and take on board some simple, effective methods to make their operations safer.

If signing up means saving someone the pain I went through, then it is absolutely worth it”.

Health and safety law requires that any construction work should be carried out, so far as is reasonably practicable, without risks to the health or safety of any person affected by the project; this includes those outside of the hoarding as well as those working on site. It will cost time, effort and no doubt some real hard cash to reduce work related road risks - but how much could it cost if you don’t? 

Can you put a price on life or reputation?
