What does “black spot” refer to in road safety?

In the context of road safety, “black spot” refers specifically to locations where there is a high frequency of accidents. These areas are often identified through statistical analysis of traffic incidents and are targeted for safety interventions. The designation of a black spot signifies that these locations pose a significant risk to road users, necessitating measures such as enhanced signage, road improvements, or enforcement efforts to reduce accidents and improve safety.

Identifying these black spots is critical for road safety professionals, as it allows for strategic planning and allocation of resources to areas where they are most needed. The other options, while related to road safety in different aspects, do not convey the same focus on the historical data of accidents that defines a black spot. Traffic enforcement areas, zones for speed limit changes, and locations with poor visibility might all contribute to safety issues but do not directly encapsulate the concept of a black spot as an area with a documented history of frequent accidents.
