Artikel 15

Advance direction signs shall be placed at such distance from the intersection as will make them most effective both by day and by night, having regard to road and traffic conditions, including the normal speed of vehicles and the distance at which the sign is visible; this distance need not exceed about 50 metres (55 yards) in built-up areas but shall be not less than 500 metres (550 yards) on motorways and other roads carrying fast traffic. The signs may be repeated. An additional panel placed below the sign may show the distance between the sign and the intersection; this distance may also be shown on the lower part of the sign itself.
