A roadworks and quarry company has been fined a total of €1.2 million following a fatal incident at a roadworks site in County Donegal that resulted in the deaths of three members of the same family and serious injuries to a fourth.
The case, heard before the Circuit Criminal Court in Letterkenny, arose from an investigation by the Health and Safety Authority (HSA) into an incident that occurred on the evening of 20th August 2020.
The Incident
The court heard that a family was returning home after a day out when their vehicle encountered a section of roadworks. The front left tyre of the car left the carriageway and entered an unfinished hard shoulder. When the driver attempted to correct the vehicle’s path, it aquaplaned on the newly laid road surface, crossed the roadway and entered Lough Foyle.
The driver and two of his children lost their lives in the incident. The driver’s wife, who was also travelling in the vehicle, was rescued by emergency services but sustained injuries.
HSA Investigation Findings
The HSA investigation found significant deficiencies in the temporary traffic management arrangements at the roadworks site. Investigators determined there was a lack of adequate temporary traffic management measures, including appropriate signage and traffic cones, to safely guide motorists through the works area.
Evidence presented to the court revealed that a specialist traffic management contractor engaged for the project had been stood down earlier on the day of the incident. The roadworks company subsequently installed its own signage and traffic management measures. In addition, due to adverse weather conditions, planned resurfacing works on the road’s hard shoulders had been postponed.
Charges and Guilty Plea
The company pleaded guilty to breaches of Section 12 of the Safety, Health and Welfare at Work Act 2005. The charges related to its failure to ensure, so far as was reasonably practicable, that persons not in its employment were not exposed to risks to their safety, health and welfare arising from work activities.
The offences included failures that resulted in the deaths of three people and injuries to a fourth person.
Court’s Decision
In sentencing, Judge Roderick Maguire said there had been a failure to properly manage the roadworks operation. He noted that the traffic management arrangements in place were inadequate and that no inspection of the revised traffic management system had been carried out after the original contractor was stood down.
The court also heard evidence in mitigation, including details of the company’s safety certifications, documented inspection procedures and use of competent traffic management contractors. The CEO of the company’s parent organisation acknowledged that the standards required had not been met and stated that the tragedy should never have occurred.
While noting that the offences were not motivated by “greed or badness”, Judge Maguire described the incident as a devastating tragedy.
The court imposed a fine of €1 million in relation to the offence that resulted in the deaths of three people and a further €200,000 fine relating to the injuries suffered by the surviving family member, bringing the total penalty to €1.2 million.
Key Lessons for Employers
This case serves as a stark reminder of the critical importance of effective temporary traffic management measures on roadworks projects. Employers undertaking roadworks must ensure that appropriate controls, signage, inspection procedures and competent oversight remain in place at all times, particularly where changes are made to planned traffic management arrangements.
Commenting after the case, HSA Chief Executive Mark Cullen said the prosecution highlights the potentially catastrophic consequences that can arise when traffic management controls are not adequately implemented and maintained, emphasising employers’ obligations to protect members of the public from risks associated with roadworks activities.
For employers involved in construction, roadworks and infrastructure projects, the case underlines the importance of robust risk management, continuous supervision and compliance with safety obligations under the Safety, Health and Welfare at Work Act 2005.
