It is unlikely that many of the motor racing enthusiasts basking in the Silverstone sunshine and enjoying a thrilling British Grand Prix on Sunday gave a moment’s thought to an obscure four-year-old European court case involving a Slovenian farm worker. 

But Motor Sports Association chairman David Richards was thinking about it, as was the most important man in world motorsport, Jean Todt – and, after meeting with the aforementioned pair at Silverstone on Sunday, so too was our government's very own transport secretary, Chris Grayling. 

The subject is important to the sport’s most influential figures because changes to the law resulting from the case threaten to drive up the cost of competing in motorsport, particularly at a grassroots level, and add layers of complexity that could cause some forms of club competition to cease completely.

The case in question – Damijan Vnuk versus Zavarovalnica Triglav – dates back to 2014. Vnuk, a farm worker, sought compensation for injuries sustained when he was knocked off a ladder by a trailer attached to a tractor that was reversing across a farmyard. Vnuk’s argument was that the insurers of the tractor should compensate him. The Slovenian court disagreed because the incident occurred on private land - but the European Court reversed the ruling. 

It became a complex issue that hinged on the EU’s interpretation of whether vehicles operating on private land are required to be covered by compulsory insurance regardless of how they are being used. The European Court decided that they did, as long as that use is consistent with the normal function of the vehicle. 

As it stands, this ruling would require all competition cars in motorsport – from short oval stock car racing to hillclimbing – to have compulsory third-party insurance. 

Many competition vehicles are already road registered, taxed, MOT’d and insured, but this insurance is usually limited to their activities on public roads, and not during competitive sections on private land. A similar situation applies to vehicles on track days.
