 that when a vehicle is being used on such an occasion as is specified in paragraph (1)(b), the foregoing prohibition prescribed by this sub- paragraph shall not then apply to that vehicle but instead the prohibition conveyed to it on that occasion by the red signal shall be the same as that provided by paragraph (1)(b) in relation to the vehicle mentioned in that paragraph,

(b) subject as provided in sub-paragraph (d) of this paragraph, the amber- with-red signal shall denote an impending change in the indication given by the signals from red to green (where a green signal is provided) or from red to a green arrow or arrows but shall not alter the prohibition conveyed by the red signal;

(c) the green signal (where a green signal is provided) shall indicate that vehicular traffic may pass the signals and proceed straight on or to the left or to the right;

(d) any green arrow during such time as it is illuminated shall indicate that vehicular traffic may pass the signals and proceed in the direction indicated by the arrow notwithstanding any other indication given by the signals;

(e) the amber signal shall, when shown alone, convey the prohibition that vehicular traffic shall not proceed beyond the stop line, or if the stop line is not for the time being visible, beyond the signals, except in the case of any vehicle which when the signal first appears is so close to the said line or signals that it cannot safely be stopped before passing the line or signals.

(3) Vehicular traffic passing any light signals in accordance with the foregoing provisions of this Regulation shall proceed with due regard to the safety of other users of the road and subject to the direction of any police constable in uniform or other duly authorised person who may be engaged in the regulation of traffic.

(4) The significance of the light signals prescribed by Regulation 31(3) shall be that the intermittent red lights when displayed at the side of the carriageway convey the prohibition that vehicular traffic shall not proceed beyond those lights and when displayed over the carriageway so as to operate in relation to vehicular traffic proceeding in the traffic lane (as defined by Regulation 36(1)) situated immediately beneath them, the said lights convey the prohibition that such vehicular traffic as aforesaid shall not proceed beyond those lights:

Provided that this paragraph shall not apply to a vehicle when it is being used on such an occasion as is specified in Regulation 34(1)(b); and for that vehicle when it is being so used, the intermittent red lights whether so displayed at the side of or over the carriageway shall have no significance.

(5) The significance of the light signals prescribed by Regulation 31(4) shall be as follows:—

(a) the amber signal shall convey the prohibition that vehicular traffic shall not proceed beyond the stop line on the carriageway provided in conjunction with the signal or, if that line is not for the time being visible or there is no stop line, beyond the signal, except in the case of any vehicle which when the signal first appears is so close to the said line or signal that it cannot safely be stopped before passing the line or signal; and

(b) the intermittent red signals shall convey the prohibition that vehicular traffic shall not proceed beyond the stop line on the carriageway provided in conjunction with the signals or, if that line is not for the time being visible or there is no stop line, beyond the signals.

(6) For the purpose of this Regulation the expression "stop line" means the traffic sign shown in diagram 1001.
