A free resource developed by National Highways with industry experts to assist employers investigate vehicle related incidents.
The investigation of incidents and near misses should form part of an organisation’s safety management system as well as part of its commitment to health and safety. Driving for work incidents should be treated the same as any workplace incidents, requiring investigation to identify causes and potential remedial steps to reduce the likelihood of similar events occurring in the future.

Guide to Incident Investigations
Why do we need an Incident Investigation Process?
A good investigation will examine all the elements of the operation which can contribute to near misses or collisions. Investigations can reveal the gaps between stated policies and day-to-day practices.
Having an incident investigation process in place will help employers manage the risk of work-related driving. This guide will help employers:
- identify and understand their immediate and underlying causes
- report and record work related road incidents and near misses
- learn lessons and share that learning across the organisation
- put in place measures to reduce the likelihood of similar incidents happening again
What are the benefits of Incident Investigation?
The benefits to employers who embrace and adopt this approach to incident investigation may include:
- keeping employees who drive for work, safe while at work
- keeping other road users safe
- reducing business interruption
- reducing incident related costs
- promoting safe driving habits and skills for employees
- complying with the law and reducing risk of prosecution for failing to fulfil legal obligations
