In the first year, to renew road tax then the vehicle would need to have a current mot, before the exemption could be applied for. It is thought by the FBHVC that having to have a current mot on a vehicle that is potentially mot exempt does not make sense. Further guidance is to be issued before 20th May. So with ony a few weeks to go it is unclear as yet what the new procedures will be for mot exemption.
To me it does not make sense to self declare that your vehicle is roadworthy, most people will make the declaration regardless.
I'm not sure why the FBHVC think that the bike will have to already be MoT'd to apply for exemption TBH - the DVLA document already referenced (and copied and pasted below) seems to state pretty clearly that you don't to me..
How to declare a vehicle for the 40 year MOT exemption
Vehicle keepers are required to ensure that their vehicles are taxed when used on a
public road. From 20 May 2018, at the point of taxing a vehicle, the vehicle keeper
can declare their vehicle exempt from MOT if it was constructed more than 40 years
When declaring an exemption, you will be required to confirm that it has not been
substantially changed (as defined in this guidance). This process will be applied to
pre-1960 registered vehicles, as well as newer vehicles in the historic vehicle tax
If the vehicle does not have an MOT and you wish to continue using it on the public
roads, you will have either to undergo an MOT or, if you wish exemption from the
MOT, to declare that the vehicle is a VHI.
If the vehicle has a current MOT certificate but you anticipate that on expiry of that
certificate you will wish exemption from future MOTs you will at the time of
relicensing be required to declare that the vehicle is a VHI.
In addition, Jeff responded to my question about if you have to fill in the V112 every year by telling us it is a one-off and therefore once registered as a VHI it will always be MoT exempt.
