14.24 Sizes, maximum recommended spacing and minimum visibility distances for repeater signs are shown in table 14-4. Repeater signs should be staggered on alternate sides of a single carriageway road, or on alternate sides of each carriageway of a dual carriageway road, in accordance with table 14-4. Guidance on the mounting of repeater signs, and co—location with other signs, can be found in paras 14.61 and 14.62. At a junction where the major road has a higher speed limit than the side road, it will be necessary to reduce the spacing of the repeater signs on the major road where these are used to indicate the speed limit to drivers entering from the side road, as the signs must be no more than 100 m from the junction in both directions (see para 14.12). Where this would result in a repeater sign being close to a terminal speed limit sign on the major road, it might be better to omit the repeater and use two terminal signs for traffic leaving the side road (see paras 14.12 and 14.13).

NOTE 1: For the purposes of direction 11, street lighting or lit carriageway means "a system of carriageway lighting furnished by lamps lit by electricity placed not more than 183 metres apart in England and Wales or not more than 185 metres apart in Scotland". Where a road does not have a system of street lighting throughout and requires repeater signs for both the lit and unlit sections, a repeater sign should be provided at the point where the street lighting commences.
NOTE 2: Sign size, spacing and clear visibility distance for motorways, including link roads, will be the same as shown for 40 mph, 50 mph and 60 mph, as appropriate. Repeater signs are not used on motorways to indicate the national speed limit, whether or not there is street lighting. NOTE 3: Repeater signs need not be provided where the length of the speed limit is less than the distance shown in this column. |
