The LLM advised all highway users to slow down and obey the instructions of officers at the scene following the spill at Kilometer 30.5 eastbound.

Why Did the Road Look Like It Was Covered in Snow?

The road surface appeared to be covered in snow because a white, foamy liquid had spilled across the asphalt, creating a visual effect that resembled a winter landscape. This unusual sight on a Malaysian highway, where snow is not a natural occurrence, prompted several road users to share videos and photos on social media, with some expressing surprise at the foam-like appearance.

One user on Thread, @umminazali, commented on the unusual condition of the highway, noting the foam-like texture. The viral nature of the incident was amplified by the stark contrast between the white substance and the typical dark asphalt of a tropical highway. The exact chemical composition of the liquid remained unknown, and the LLM had not yet identified the source of the spill.
