SIGNING PRINCIPLES

606

D4.8.14 The "turn left/right” sign to diagram 606 indicates to drivers the direction in which they must proceed. This sign must not be used without the necessary order (except the "turn left" sign when used on the main island of a roundabout or in combination with diagram 608 "Dual carriageway"), or as a directional sign.

609

D4.8.15 The "turn left/right ahead" sign to diagram 609 is used to indicate that drivers must turn left or right at a junction ahead. This sign must not be used without the necessary order, or as a directional sign, except at a road approaching its junction with a dual carriageway road.

610

D4.8.16 The "keep left/right" sign to diagram 610 is a regulatory sign, which indicates to drivers that they must pass the sign on the side indicated. No order or departmental site approval is required for its use.

612

613

D4.8.17 The "no right turn” sign to diagram 612 and the "no left turn" sign to diagram 613, in conjunction with the necessary order, can be used when a side road is closed and traffic cannot turn into it. In such a case the traffic has to divert by travelling ahead.

D4.8.18 It is important to note that the "keep left/right” sign to diagram 610 and "turn left/right sign" to diagram 606 must be correctly mounted in order to convey the intended message; see Chapter 3. Some device must be incorporated in portable frames to prevent the accidental rotation of circular signs. They must not be used to direct pedestrians when footways are diverted. The "direction of temporary route for pedestrians" sign to diagram 7018 should be used in these circumstances.
