One of the buses was speeding in the wrong lane when the accident occurred before dawn in Khanh Hoa province, said Phan Van Cuong, deputy head of the provincial Traffic Police Department.

Rescue workers had to use a saw to free passengers trapped in the wreckage.

Twenty-three of the injured were in critical condition, doctors at Cam Ranh Hospital said.

Nearly 10,000 people died in traffic accidents in Vietnam last year, the Ministry of Transport said. That number was down 14% from the year before amid a government campaign to reduce accidents.

More than 90% of the world’s road deaths occur in low- and middle-income countries even though these counties have fewer than half the world’s vehicles, according to the World Health Organization.
