From my understanding, it is against the law to disobey a lawful order. I have been told that the way out is to ask explicitly 'Is that an order?', as you can not be charged due to following a lawful order. Maybe someone can confirm this, as at best, I have hearsay.
Either way, 'you can beat the rap but not the ride'.
