Police believe that the driver, who was killed in the accident, fell asleep at the wheel and the bus veered off the highway, overturning and then slamming into an LPG gas station, reported the Chiang Mai Mail.
Police said it was fortunate that the bus did not hit any of the LPG tanks, which could have exploded.
The blue-and-white New Viriya Tour bus veered off the highway around midnight before sliding into a fence and then the LPG gas station at Ban Tha Pha in Lampang.
Rescue officials had to
cut passengers out of the bus and survivors were transported to hospital.
