OK thanks. So could you clear up on the MUST NOT enter unless exit is clear ? Since accordingly above, If I enter, but my exit is not clear, but I keep moving (i.e. do not stop) and successfully clear the box (the vehicle in front cleared it so I could too, for example) , is that an offence ? It doesn't look like it to me, although the hwaycode says MUST NOT that actual law above does not say that?
