Abstract
According to road accident statistics in 2023 in Thailand and Pathum Thani Province, most accidents occurred on highways, involving motorcycles, male drivers, and individuals aged 20–29 years. On October 16, 2023, a joint investigation team, including local authorities, conducted an inquiry into a road traffic accident involving four vehicles on Phahonyothin Road, Highway No. 1, Pathum Thani Province. The investigation aimed to describe the incident, identify contributing factors, and propose preventive measures to mitigate future accidents and injuries. Data were collected from hospital records and interviews with individuals involved in the incident, and injury factors were analyzed using the Haddon matrix. The accident occurred involving 21 individuals: 1 severely injured, including a laceration on the lower lip, broken front teeth, and a brain hemorrhage. This individual, a passenger in a public van, was seated in the front left seat without wearing a seatbelt, which bore the brunt of the collision impact. 6 moderately injured, and 14 with minor injuries. The injured included 8 males 13 females, with an average age of 35.71 years, ranging from 14 to 59 years old. The vehicles involved were a private pickup truck, a modified gas-carrying pickup truck, a passenger van, and a motorcycle. The investigation identified several contributing factors: (1) The driver of the first vehicle was driving against traffic for approximately 1 kilometer, had a history of schizophrenia, and was unfamiliar with the route; (2) The modified gas-carrying truck was overloaded; (3) The passenger van was carrying more passengers than legally allowed, with two standing passengers and several without seat belts; and (4) The accident occurred near a road junction within 200 meters. Proposed preventive measures include stricter enforcement of traffic laws, more rigorous licensing processes, thorough vehicle inspections, and public education on road safety compliance.
