Every year in China have sanitation workers died in a traffic accident, and mainly at night or in the early hours of the morning.It's extremely dangerous for them to walk across the street to clean up the road where traffic facilities are not perfect.The design reminds drivers to be careful when sanitation workers are working along the roadside or on the middle of the street. The belt forms a red warning circle around the cleaner and when they are about to go through the bushes or walk by the cars parked along the road,the circle can be seen by drivers rapidly passing by.
