 recommendations in the following paragraphs provide for modification of some of the symbols.

Cross Roads

37. The cross roads sign which we recommend is shown in diagram 1. It differs from that now used only in that the length of the arms of the symbol has been increased. Diagram 14 shows the recommended arrangement of reflecting lenses. The sign should not be used where direction signs clearly visible to approaching traffic give adequate warning of the existence of the junction.

Roundabout

38. The recommended roundabout sign shown in diagram 2 is similar to that now used, but the thickness of the curved arrows in the symbol has been increased. Diagram 2a shows the recommended arrangement of reflecting lenses. The.sign should not be used where approach direction signs of the type shown in diagram 84 give to approaching traffic adequate warning of the existence of the roundabout.

Slow—Major Road Ahead

39. We recommend the “Slow—Major Road Ahead’ sign shown in diagram 3. It differs from the existing sign in that the over-all height of the plate has been increased by 1 in. and the triangle in the symbol surmounting the sign has been inverted to have its apex downward. We have mentioned in paragraph 13 that the latter alteration has been made to accord with International practice. Diagram 3a shows the recommended arrangement of reflecting lenses.

Road Junction

40. We recommend the road junction signs shown in diagrams 4, 5 and 6. As compared with the existing signs, the arms of the symbols have been lengthened and their ends finished square. Diagrams 4a and 5a show the recommended arrangements of reflecting lenses. The signs should not be used where direction signs, clearly visible to approaching traffic, give adequate warning of the existence of the junctions.

Bend and Double Bend

41. For the reasons given in paragraph 13 we recommend that the sign shown in diagram 7 and the existing “Double Bend” sign employing the same symbol should be replaced by those shown in diagrams 9, 10, 12 and 13 as soon as it is found possible to modify this country’s commitments under the Paris 1926 Convention.

Until such time as it may be possible to take action on the foregoing recommendation, we recommend that the form of the agreed International symbol shown in diagrams 8 and 11 should be used in preference to the existing symbol shown in diagram 7.

Diagrams, and  show recommended arrangements of reflecting lenses.

Bends

42. There are roads on which bends occur so frequently as to make it undesirable to erect a sign at each individual bend. In these circumstances we recommend the use of the sign shown in diagram 14. The length of road to which any one sign relates should not exceed 2 miles, and the sign should be used only where specially authorised by the Minister.
