Attached for information is a PDF copy of the Club's substantive response to the EU's public consultation on the Vnuk Motor Insurance Directive (MID) which I submitted today.

A copy of NPTCC's full EU consultation questionnaire response is below (if you're sad enough to want to read it!!)

Please note that only questions relevant to our activities have been answered - Questions 27- 32 as applicable. Other questions are left blank.

Notes from the MSA Trials Committee

Technical MattersPosted by Colin Campbell Mon, October 09, 2017 11:31:53
These notes originate from the MSA Trials Committee's last meeting in July and have just been published in the latest edition of iClear Round, the BTRDA's electronic newsletter.

I thought the topics would be of general interest and give a heads up on what may be in the offing.

Trials Safety

One of the MSA’s key roles is keeping competitors and organisers safe, to that end each MSA committee has been tasked with creating a short list of safety points that covers their discipline. [A pdf copy of the trials one is below.] You have to remember that this covers all trials disciplines so some of the points may not be 100% relevant to sporting trials directly, but it’s worth a read. We have now been asked to recommended a best practice for safe exiting of a section for each discipline.

MSA Trials Tips - see pdf copy below:

Car Sharing

A point raised by Martyn Haliday and the HSTA guys but something that will be worth pursuing on our side of the sporting trials fence is a wording tweak in the rules that allows a car to be the entry not just the driver. While the words remain the same in the 2018 blue book they are now italized so clubs can alter them in their event regulations. What this means is that the car does each hill once but you can swap who drives which hill, so if a novice driver wants to start or you just want a bit of fun with your friend then you can pick and chose which hills you want to do. However remember any crew member must be signed on for insurance. You would not be featured in the results as you won’t have completed all the hills but if more than one car was doing the same thing then there could be class created for it. This is very popular with the HSTA guys, two friends wanting a fun day out.


One of the most critical components in a trials car, hidden in an axle or gearbox not seen by anyone. With rudimental method’s of testing its very easy to end up with mistrust and ill feeling around the subject. If the world was a perfect place we would have a machine that generates a figure which is a pass or fail. A couple of test rigs have been created and testing is being carried out, a database is being built up to see if anything can be ascertained, at this point test method’s are being developed and fine tuned but nothing concrete has been decided.

The MSA TAP (technical advisory Panel) requested to see an example of a “ super diff” one was obtained from a used classic trials beetle (same gearbox as used in some sporting trials cars) the MSA TAP released the following statement based on the diff presented:

Superdiff - MSA TAP Statement

“Having viewed a physical differential and images of the Superdiff it was agreed that the design of the internals have been deliberately manipulated so that internal friction under load provides a locking function. Acknowledging the way these internals interact to provide a locking function it can only be described as a locking differential and thus does not comply with the Trials regulations.”

The MSA want to make it very clear that this statement is based upon the diff presented. However the diff presented was an off the shelf diff unmodified and fitted in a VW beetle trials car. The MSA are taking the diff situation very seriously and looking to put things in place to ensure all cars are being used in accordance with the rules. For 2018 Championship the MSA may have a rule added which means if you wish to take part in the MSA championship you must have the facility to have your diff sealed (as simple as small dill hole through a couple of diff studs for sealing purposes).


A proposal has been put forward to make sporting trials more accessible and break down barriers for people with cars who haven’t been out for a while. A proposal has been put forward to create a class for people who have a car but don’t have the latest spec tyres, but are running a previous Blue Book tyre. You would be running in a separate class you would not be eligible to win events overall or score championship points but you are welcome to come out have a bit of fun and it maybe the spark you need to reignite your passion for trials which makes you think about getting the right tyres and joining the full event and the relevant championships. Event organisers will not need to get extra awards it is just something to maybe get a few people back out by breaking down barriers. It will be important that organisers recognise these cars are not eligible for awards and must not be featured in the overall results.
