Catalogue section 3.18

Other signs (S-900–S-993)

Warnings and information that do not fit the catalogue's other families.

How to recognise them: A rectangular plate carrying the symbol or wording of what it warns of or tells you.

How this group is laid out

Whatever fits no other family in the catalogue ends up here, and it falls into themes. One is the border: S-920 says you have entered Spain by road from another country, S-930 names the country the road is heading for, with the distance to the border, and S-940 sums up Spain's general speed limits by class of road and in urban areas. Another is emergencies: fire extinguishers and telephones (S-910, S-960 and S-970), and emergency exits, either adjacent (S-980a and S-980b) or further on, with the direction and the distance left to go (S-990a and S-990b).

The S-991 series warns of enforcement devices: for speed by type of road, for passing a red light or a STOP, for the minimum gap between vehicles, and for speed from the air, such as a helicopter or a drone. The S-992 series turns the gap between vehicles into something you can count: the chevron road markings, or the light beacons in fog, to leave between you and the vehicle ahead. The group ends with fire risk (S-900), the radio frequency carrying road information (S-950) and S-993, which warns of the risk of rear-end collisions on uphill motorways or autovías, where lorries travel considerably more slowly than cars.

How to tell them apart

Signs in this group that look alike, and what separates them according to their definitions.

S-980aS-990a
S-980a shows the position of the nearest emergency exit, next to the sign. S-990a shows the direction it lies in and the distance left to reach it.
S-991aS-991bS-991g
S-991a and S-991b warn of a speed check at a point or along a stretch, the first on a conventional or multi-lane road and the second on a motorway or autovía. S-991g warns of possible speed checks from the air, by helicopter or drone.
S-992aS-992e
S-992a tells you how many chevron road markings to leave between you and the vehicle ahead on a stretch with frequent rear-end collisions. S-992e counts light beacons instead, on stretches where fog often cuts visibility.
S-910S-960S-970
S-910 marks a fire extinguisher, S-960 an emergency telephone, and S-970 both together.
S-920S-930
S-920 tells you that you have entered Spain by a road coming from another country. S-930 names the country the road is heading for, with the distance to the border.
