Police and rescue services rushed to Jomtien Sai 2 after a foreigner and a Thai woman came off a motorcycle at a bend.
Nongkhran, 35, suffered two broken legs and was found face down next to an unidentified foreigner who was unconscious after the 6 am accident on Saturday.
CPR was given to the foreigner at the scene before both victims were taken to hospital.
They appeared to have lost control on their Yamaha T-Max motorcycle and collided with a tree.
77kaoded said that locals have called that stretch of road the “Bend of Death” after a series of accidents where people have died and been injured.
