A total of eight vehicles were involved in a multiple-car pileup on the Yokohama Bay Bridge on Monday morning that left 10 people injured, the Kanagawa Prefectural Police said.

Although no one was seriously hurt, all 10 were sent to hospitals, authorities said.

Police said a heavy-duty truck slammed into the rear of a passenger car, causing the pileup on the in-bound line of the Bayshore Route six-lane highway.

Authorities were investigating the causes of the accident.
