Police said Krissada Chanwiang, 38, was killed by a speeding Toyota Fortuner on Suwinthawong Road near the entrance to Wat Ton Tan in Muang district at about 9.45pm.
Another motorist pursued the Fortuner and could not catch it, but managed to take a photo of the licence plate for the police.
Krissada, a driver employed at Kasemraj Hospital, was waving motorists around the flipped car of Suphannee Doksaba, 45.
He had stopped to help and called for an ambulance.
Suphannee had lost control of her vehicle and was knocked unconscious when it flipped into a ditch between lanes. She was taken to Buddha Sothon Hospital.
