The correct answer is: To provide visibility in case of roadside emergencies

A reflective triangle or flare serves a crucial function related to safety during roadside emergencies. Its primary purpose is to provide visibility, making it easier for other drivers to see a vehicle that may be disabled or stopped on the roadside. When placed at a sufficient distance behind the vehicle, the reflective triangle or flare alerts approaching traffic of the potential hazard ahead, helping to prevent accidents. This visual signal is particularly important in low-light conditions or adverse weather, where visibility may be compromised. The reflective properties of the triangle or flare ensure that they can be seen from various angles and distances, thus making the vehicle more noticeable to oncoming traffic. This increase in visibility is essential for both the safety of the individuals in the stopped vehicle and the drivers approaching the scene, emphasizing the importance of roadside safety measures.
