Ordinary coppers don’t know the rules so ignore it so chances are your not get pulled what ever your doing lol. If it go’s wrong then vosa and the traffic cops who do know the rules turn up.
Thanks for the heads up about vosa not existing them fookers have been turning up at my work for years pretending to exist and going on about tacho law checking are tacho work equipment and records are legal and right and what fines they can dish out. Never knew they was pretending I’ll tell them to fook off next time but I guess your right as there now called the dvsa
