A driver in Changzhou, Jiangsu, narrowly avoided four people holding ‘asphyxiation warning’ signs in the center of the road at night. No standard traffic warning signs were present, prompting police investigation into improper roadside work protocols.

Social Context

Under China’s Road Traffic Safety Law and GB 5768–2022 national traffic signage standards, construction zones must deploy reflective cones, flashing lights, and advance warning signs. Informal or unregulated roadside activity—especially by non-professionals—violates occupational safety mandates enforced by local transport bureaus and emergency management departments.

Safety Tip

Slow down and prepare to stop when approaching any unexpected personnel or objects on roadways, especially at night or in low-visibility conditions.
