Guardrails get scrubbed clean with unique device in China's Shandong
A cool video from eastern China shows how a guardrail-cleaning vehicle scrubs out dirt in the middle of a road.
The clip was shot in Tai'an City in Shandong Province on March 6.
The filmer said it was the first time he saw the guardrail-cleaning vehicle, as previously guardrails used to be cleaned by sanitation workers.
