    Jon-Paul PRIGENT · Prevention of Future Deaths report

    Report summary

    Jon-Paul Prigent died on 30 July 2020 when a soil-laden trailer decoupled from its tractor, overturned, and compressed the car in which he was sitting, causing asphyxiation. The principal concerns were the absence of periodic independent testing for agricultural tractors and trailers, the lack of required safety features to prevent decoupling, and the risks posed by worn, overloaded, and unevenly loaded equipment used on public roads.

    How this individual concern was interpreted

    PFD Monitor created a concise, searchable interpretation from the report wording shown below. The report was sent to Agricultural Engineers Association; that does not assign responsibility.

    PFD Monitor interpretation

    Failure of current agricultural tractor and trailer safety arrangements to keep pace with changing road use

    Wider context from the report

    “4. Tractors and trailers are increasingly large and carrying heavier loads due to farm consolidation and are correspondingly traveling further distances on public roads to reach more distant areas on larger farms, and agri-business depots and processing sites. The current safety arrangements have probably failed to keep up to date and relevant and were more suited to an era when agricultural use tractors and trailers might simply have been crossing a road to get form one field to another. ”

    PFD Monitor interpretation

    Lack of periodic independent vehicle testing for tractors and trailers used on roads for agricultural purposes

    Wider context from the report

    “1. Tractors and trailers driven on roads for ‘agricultural purposes’ are not subject to periodic independent vehicle testing. This places the responsibility for checking roadworthiness on the user which is clearly dependent on the diligence and competence of the user. It is therefore highly likely that some tractors and trailers are being driven on roads for ‘agricultural purposes’ in unroadworthy and unsafe condition, as was clear in Mr Prigent’s inquest. ”

    PFD Monitor interpretation

    Failure to require safety features preventing decoupling of tractors and trailers used on public roads

    Wider context from the report

    “2. Tractors and trailers driven on roads at below a speed of 25 miles per hour are not required to be fitted with safety features to prevent decoupling (e.g. a safety chain, or dual safe braking system). Therefore, if decoupling occurs there is nothing to prevent independent and uncontrolled travel of the trailer. 3. Basic hitch hook and ring coupling systems for tractors and trailers are very simple and convenient for ease and speed of coupling and use on farms but present clear risk when used on public roads without safety features to prevent decoupling. ”
