Ten motorcycles bearing Thai number plates were held as their foreign drivers violated traffic laws and could not produce driving licenses on Monday. At 8:30am on November 20, local traffic policemen found the motorbikes travelling on a banned road in district 9 near Suoi Tien Cultural Park and pulled them over. But none of the motorists were able to show valid driving papers so their bikes were seized pending investigations. Two Vietnamese tour guides accompanying the group showed a document signed by the Ministry of Transport that authorized Binh An Commercial and Tourism Services Joint-Stock Company to organize an automobile and motorcycle caravan in Vietnam for tourism purposes from November 16 to 23. The caravan is supposed to travel through Thailand - Bo Y border gate in Kon Tum - Phan Thiet, Ho Chi Minh City - Da Lat - Pleiku - and back to Bo Y border gate.
