5.3.3. Diagram 619.1 would be used where it was acceptable to permit solo motor cycles (i.e. without side cars) to use the road where other motor traffic is prohibited. Diagram 619.2 might be used where it is required to emphasise that solo motor cycles are not permitted to use a route that has been provided for pedestrians and cyclists. 5.3.4. A sign to diagram 619, 619.1 or 619.2, unlike the sign to diagram 617, does not have to be used with a supplementary plate. However, it is rarely desirable to deny access to premises or land adjacent to a road, so a plate legend such as “Except for access” should be used with these signs if the traffic order permits. The prescribed legends for exceptions are the same as those for diagram 617 (S3‑3‑15, see 5.2.3). The plate may indicate time periods (S3‑3‑8) where the order does not apply continuously or where the exceptions apply only at certain times. Some exceptions are not appropriate for the plate used with the sign to diagram 619.2. Examples of plate legends are shown in Figure 5-11.
