Employers have been reminded that they may face car accident compensation claims if they do not take steps to ensure safety at roadworks.
The warning follows a Health and Safety Executive (HSE) investigation into a severe collision at the A1060 at Boyton Cross, near Chelmsford, which left one motorcyclist in intensive care.
Workers at the site had put into place an inappropriate road layout that was unsuitable for traffic flows, putting road users in danger, the investigation found.
"This serious incident could and should have been prevented by the company by ensuring safe systems of working were in place," commented HSE inspector Sandy Carmichael.
"Where information to road users at roadworks is not prominent, accurate and clear, both workers and road users are at great risk."
The Highways Agency’s Safer Driving Through Roadworks campaign aims to highlight and reduce the number of deaths and injuries to roadworkers in the UK.
