A Bangkok-Ubon Ratchathani air-conditioned bus overturned on a road in Buri Ram's Prakone Chai district at 2am yesterday, injuring 40 passengers.
Of them, 13, including two under five, were in serious condition.
The victims were rushed to Prakone Chai Hospital. Six severe cases were referred to Buri Ram Hospital.
The bus driver told police that the road was slippery because there was construction on it and heavy downpours at the time.
In Nakhon Ratchasima's None Sung district, a 10-wheel oil tanker hit four workers affixing reflective markers on Mittrapap Road in the morning.
Two workers one of whom was named as Chokchai Khiewaram and the contractor, Ratchasak Charoenkulchaiyaporn, 35, died at the scene while another worker, Suriya Akkachart, was badly injured.
The driver, identified as Pongrit Boonra, was also killed because his truck crashed into the back of the six-wheel truck of the contractor.
