A semi-trailer sped along a highway without a driver for 1.2 kilometers in Shijonawate, Osaka, on Tuesday morning.
Police said the truck traveled along the shoulder of the highway, crashing into cars, before colliding with the guardrail and coming to a halt, TV Asahi reported Wednesday.
The driver of one car sustained a broken finger when his car was hit by the truck. Police said this was the only injury reported in the incident.
The 67-year-old driver of the semi-trailer was quoted by police as saying that he didn’t properly apply the handbrake when he left his vehicle.
