Road Traffic Accidents at Work: When Does RIDDOR Apply?

Start With The Road-Traffic Rule

Does every work journey collision require RIDDOR reporting?

No. Working at the time does not, by itself, make a moving-vehicle injury on a road reportable. Regulation 14 restricts the ordinary RIDDOR duties where injury or death arises from vehicle movement on a road. Start with the exact location, public access and causal movement before considering severity.

Record the location more precisely than “at work”. For England and Wales, the Regulations define a road as a highway or another road to which the public has access. HSE guidance commonly explains the practical position using “public road”. Preserve both formulations: the statutory text controls, while the guidance helps teams apply it. A motorway collision during a delivery can therefore sit outside RIDDOR even though the driver was working.

Vehicle ownership is not a legal shortcut. A company car, liveried van or scheduled route may establish work context, but it does not cancel regulation 14. Nor does a severe outcome automatically displace the restriction. Ask what actually caused the injury. If vehicle movement on a statutory road caused it, the restriction is the starting point.

Employer and fleet first-pass record:

1. Make the scene safe and follow emergency procedures.
2. Record the road name, site boundary and normal public access.
3. Record whether vehicle movement caused the injury or death.
4. Note the work task without assigning blame.
5. Preserve photographs, witness details and dispatch records lawfully.
6. Open separate RIDDOR, police, insurer and internal-recording workstreams.

With the road and causal movement recorded, the four statutory exceptions can be tested without guesswork.

Check The Four Statutory Exceptions

Which road incidents can remain within RIDDOR?

Four defined situations can remain within the normal reporting analysis: an accident involving a train; exposure to a substance conveyed by the vehicle; loading or unloading; and qualifying work on or alongside a road. An exception removes the road restriction only. Work-relatedness and a reportable outcome must still be proved.

Test the activity that produced the outcome, not the worker’s broad job description. HSE’s example of a delivery driver struck while unloading shows the difference. The potential exception is loading or unloading, not delivery driving in general. Likewise, a worker injured within a coned roadworks area may fall within the road-work exception because of the specified task, not simply because that person worked near traffic.

The road-work wording has defined edges. It covers construction, demolition, alteration, repair or maintenance involving the road, its equipment, markings or boundaries; adjacent pipes or cables; and structures beside or over the road. Do not replace that statutory list with the loose label “roadside worker”.

If an exception or genuinely private route keeps the review open, the next question is whether work caused the event.

Decide Whether Work Caused It

What proves the accident was connected with work?

A RIDDOR accident must arise out of or in connection with work. Relevant evidence concerns how the undertaking was conducted, the plant or substances used, and the premises condition. A workplace address, working hours or a company vehicle can be relevant, but none proves the required causal connection alone.

Use a two-scene comparison. A delivery truck and lift truck collide on a genuinely private depot road while both perform controlled work tasks. Normal RIDDOR tests can apply. In another scene, two shoppers collide in a supermarket car park. The business address alone does not make that event work-related. The answer could change if staff traffic directions or an obstruction created by the undertaking contributed.

For a fleet investigation, ask what changed because of work. Did a depot plan impose the reversing route? Did defective traffic controls contribute? Was the driver loading under an employer’s system? Did equipment, a substance or premises condition create the risk? Record counter-evidence too. A conclusion is more reliable when the note explains why apparently relevant facts did not meet the test.

Work-connection decision note:

• Activity: What task was actually being performed?
• Control: Who set the route, method, equipment or premises condition?
• Mechanism: How did that work factor cause or contribute?
• Access: Did the public normally use the road?
• Counter-evidence: Could the event have happened in the same way without the work factor?
• Boundary: Do not use this assessment to decide negligence or insurance liability.

A documented work connection prepares the responsible person to apply the correct outcome threshold.

Test The Injury Threshold

Which worker outcomes meet a reporting threshold?

For a worker, a work-related accident may be reportable if it causes death, a specified injury or more than seven consecutive days of incapacity for normal work. Exclude the accident day but include weekends and rest days. Apply the road restriction and exception analysis before using any outcome threshold.

Do not count only rostered shifts. “Consecutive days” includes days that were not working days. The question is whether the worker was away from work or unable to perform normal duties because of the injury for more than seven consecutive days. For this category, HSE says the report must be made within 15 days of the accident. That is not the universal deadline for deaths, specified injuries or every other RIDDOR category.

An over-three-day injury has a different consequence. It must be recorded, but is not reportable solely on that duration. A specified injury may be reportable without waiting for an absence count. Use the current official list and legitimate diagnosis evidence; do not turn a manager’s description of “serious” into a statutory category.

Threshold checklist:

• Confirm whether the injured person was a worker or non-worker.
• Obtain diagnosis information legitimately available to the responsible person.
• Compare a worker’s outcome with the official specified-injury list.
• Count incapacity from the day after the accident, including rest days.
• Record an over-three-day case even when it is not reportable on that basis.
• Calendar the 15-day limit only for the over-seven-day category.
• Reassess when later evidence changes the classification.

Once the category and timing are clear, the reporting duty must be assigned to the correct responsible person.

Identify Who Must Report

Who owns the statutory report after an accident?

The responsible person submits the RIDDOR report. For an injured employee, that is generally the employer. Depending on the facts, responsibility may instead rest with a qualifying self-employed person or the person controlling work premises. The injured driver should provide evidence through the proper route, not assume ownership of the form.

Give drivers a clear escalation route. They need to know whom to contact, which facts to preserve and how later absence information will be captured. The employer or other responsible person should verify the classification, select the official reporting route and retain the required particulars. HSE’s reporting pages explain who should report and direct responsible persons to the current forms.

Self-employed status needs careful handling. Regulation 3 links responsibility to the injured person’s status and control of the premises or undertaking. A depot operator, principal contractor or another controller may hold the duty in some settings. A driver’s invoice, uniform or vehicle livery does not answer the question.

Responsibility hand-off:

1. The driver or supervisor submits neutral incident facts internally.
2. The fleet or safety lead confirms employment status and site control.
3. The responsible person records the road, exception and work-connection tests.
4. The responsible person checks the outcome category and its timing.
5. An authorised submitter uses the official HSE route if required.
6. The team stores confirmation and updates the internal record.
7. Uncertainty goes to competent health-and-safety or legal advice.

Clear ownership reduces duplicate or unauthorised submissions and makes it easier to keep every parallel duty separate.

Keep Other Duties Separate

What continues when RIDDOR does not apply?

A RIDDOR exclusion does not end other duties. Police reporting, insurer notification, workplace accident records, contractual notices, safeguarding and internal investigation each have distinct tests. RIDDOR also does not decide negligence, insurance liability, employment rights or any other outcome. Keep every route separately owned, timed and evidenced.

Build one incident index with separate workstreams. The same photographs or witness notes may support several routes, but each decision should state its authority, deadline, owner and status. This stops “not RIDDOR-reportable” being misread as “nothing else to do”. HSE’s motorway example points to police responsibility while explaining why most public-road movement injuries are outside RIDDOR.

The separation also protects the injured person and employer. A RIDDOR report is a regulatory notification; it is not a fault admission or an insurance decision. Conversely, an insurer accepting or disputing liability does not determine reportability. Keep neutral records and update them when verified evidence arrives.

Interactive check: Which missing fact could change your decision most: normal public access, the precise task, work causation, the diagnosed outcome, the incapacity count or the responsible person? Mark it unresolved rather than guessing.

One evidence index with separate decisions gives the organisation a defensible route for later review.
