What should be done to the blunt end of a barrier to minimize hazards?

Minimizing hazards associated with the blunt end of a barrier is crucial for ensuring safety on roadways. Flaring the end or using crash cushions is the most effective approach as it reduces the severity of impacts if a vehicle were to collide with the barrier. Flaring allows the end of the barrier to gradually transition to the roadside, which can help direct vehicles away from the hazard rather than directly into it. Crash cushions absorb the impact energy, significantly reducing injury risk for vehicle occupants.

Covering the end with soft material, while it may help reduce some risk, does not address the potential for high-speed collisions effectively. Leaving it exposed presents a direct hazard that can lead to severe injuries in the event of a crash. Painting it bright colors could improve visibility but does not provide physical protection or reduce the danger posed by a blunt barrier end. Thus, using approaches that either redirect vehicles or absorb impacts is essential for creating a safer environment at locations where barriers are present.
