(3) If—
(a) a motor vehicle being driven on any part of the relevant roads passes a speed limit sign at a particular location; and
(b) apart from this paragraph, the vehicle would be subject to a speed limit by virtue of this regulation, but would not have been subject to a speed limit by virtue of this regulation had it passed that location ten seconds earlier than was in fact the case,
