3.23 Where a side road joins either a high speed single carriageway road or a dual carriageway road with a gap in the central reservation, the marking to diagram 1003 should be used.
PRIORITY TRAFFIC SITES
3.24 Where the width of the road is such that traffic from one direction is given priority over that from the other using diagrams 615 and 811, the Give Way marking to diagram 1003 may be used with diagram 615 to indicate the place at which vehicles should wait. The marking to diagram 1023 may also be provided, but not the vertical sign to diagram 602, which is prescribed for use only at junctions or level crossings (regulation 16). A longitudinal warning line to diagram 1004 or 1004.1 should be used on the approach to this narrow section as far as the Give Way line, discontinued through the hazard and recommenced where an adequate two-way width is regained. Diagram 615 must be accompanied by the plate to diagram 615.1 "Give way to oncoming vehicles", and diagram 811 must be accompanied by the plate to diagram 811.1 "Priority over oncoming vehicles". Under no circumstances should traffic from both directions be required by the signs or markings to give way.
CYCLE PRIORITY
3.25 Regulation 25(6) enables the marking to diagram 1003 to be used to give priority to a cycle track crossing a road. The length of road crossed by the cycle track must consist of a road hump, which should be of the flat-topped type. The hump must extend across the full width of the carriageway, in accordance with direction 34(2). The marking to diagram 1023 should also be provided, together with a longitudinal warning line to diagram 1004 on each approach. The hump must be marked with diagram 1062 (see para 21.9). The Give Way marking should be placed on the carriageway of the road, not on any part of the hump.
