It was carried out to evaluate and assess types of injuries in road traffic accident and their severity reported to one of the tertiary care hospital through cross sectional systemic prospective and retrospective study. Present study was carried out among 302 road traffic accident cases of young adult age. Collection of data includes interviewing the patient and review of medical records. Non-fatal injuries with severity such as abbreviated injury score (AIS); Glasgow coma score (GCS); revised trauma score (RTS) were considered in this study. Study indicates that 74.83% of victims were male and there is a significant (p<0.01) association between AIS and male gender. Most of the accident injuries were mild in nature and 99% of victims were having abrasion in urethra. The mean severity of injuries as computed by AIS was 13.2±0.106, GCS was 14.25±0.085 and RTS was 7.89±0.234. 37.45% of accident injuries were in group from 18 to 24 years. There is a significant (p<0.05) correlation between days of admission into ICU as well as in timing of accident. We conclude that it is important for planning and execution authorities to design and develop strategies and plans to minimise injuries in chest wall and thoracic vasculature to avoid future complications in young adults
