A summary of the signs used at passing lanes is detailed in Table 4‑1. The signs for passing lanes situated in rural and urban areas are identical except for the A42-1.1 Passing lane ‘[distance] km’ ahead sign, which is only used in rural situations.
All signs should be located where approaching drivers have an uninterrupted view of them over a distance of at least 120m in rural areas or at least 60m in urban areas.
