LTA's published list
LTA's OneMotoring PDF titled Black Spot Locations lists 38 locations: 14 under arterial roads, 15 under expressways and 9 under junctions. The PDF gives road names and nearby landmarks or junctions; it does not include a map or state a publication or review date. Consult the linked PDF for the location names, bearing in mind that its revision date is not stated (LTA, Black Spot Locations).
LTA separately states that Auxiliary Police Officers must be deployed for traffic regulation duties at Black Spot locations when road works are carried out, regardless of the road category. This is road-works traffic-control guidance, not a separate everyday driving rule for motorists (LTA, Authorisation of Security Officers to Regulate Traffic for Road Works).
Coverage debt
The published list does not explain how LTA designates a location as a Black Spot, identify the collision period or counts behind the list, or provide site-specific driving instructions. Its revision date is not stated in the PDF.
