title: Pattern of accidents and injuries involving three-wheelers.
abstract: OBJECTIVE
  To study the pattern of injuries and some causative factors of three-wheeler related accidents.
  
  
  METHODS
  Prospective descriptive study.
  
  
  METHODS
  Accident unit, Colombo South Teaching Hospital, Kalubowila.
  
  
  METHODS
  One hundred patients admitted to Colombo South Teaching Hospital with three-wheeler related accidents were interviewed, examined within 24 hours of admission and followed up by using a standard questionnaire. Detailed descriptions of the accident and the types of injuries were recorded.
  
  
  RESULTS
  54 accidents took place during daytime 07.00 h to 19.00 h) and the passengers were the commonest victims (40%). Soft tissue injury was the commonest injury observed (75%). The second commonest type of injury was long bone fractures (21%). Toppling due to a sudden turn of the vehicle accounted for 30% of accidents. Of 28 drivers in the study group, 25 admitted breaking the handle-lock to increase the vehicle's turning angle. Toppling due to a sudden turn was identified as the cause of the accident in all those who had interfered with the handle-lock. At the time of the accident, 89% of the drivers and 28.1% of pedestrians were under the influence of alcohol. Alcohol was related to 67.4% of the night accidents.
  
  
  CONCLUSIONS
  Alcohol consumption was recognised as a major contributory factor, in particular for night accidents. A strong association was observed between mechanical alteration of the vehicle's handle-lock and the risk of accident. Introduction of legislation to prohibit handle-lock alteration and strict implementation of the law regarding driving under the influence of alcohol would help to reduce three-wheeler related accidents.
