A woman was killed and a man seriously injured in Ang Thong early Sunday morning when their sedan collided head-on with a trailer truck.
Deputy inspector Pol Lieutenant Suksan Passawakang said officers and rescue workers were on the scene soon after 1.30am.
The Din intersection in Tambon Phosa, Muang Ang Thong, has a single traffic light blinking at night for vehicles approaching from all directions.
The truck was heavily damaged in front. The Toyota Vios sedan, which also struck a roadside power pole, was wrecked.
Truck driver Nikhom Kwanyeun, 32, told police he was hauling rice to a factory and slowed when he saw the sedan approaching but could not avoid the collision.
Police were investigating further to see if charges were warranted.
