Abstract This study aims at examining the factors causing traffic accident at the community level and finding measures for accident prevention and accident-related risk behaviour reduction to ensure safety of people in the community. At the community level, the accident prevention consists of finding risk group, risk area, establishing community traffic safety checkpoint which is to stop and reduce risk behaviour. The data was collected by Questionnaires and observation of traffic-related risk behaviour among car and motorcycle users passing through the checkpoints in Surat Thani, Chiangmai, Phrae, Chiangrai, and Konkean during Songkran Festival in 2015. The result shows that during 9–15 April 2015 of Songkran Festival (data from 10 provinces, 22 districts), there were 121 injuries, 6 of them had to be admitted to the hospital and there was no death.

Compared to 2014, death reduces by 5, injury reduces by 553, and number of crash victims who were admitted to the hospital reduces by 20. Also, it is found that traffic accidents heavily occurred on 12–14 April. From Alcohol breath test results, it is highlighted that alcohol level of drivers is especially high during 9–13 April. With regard to helmet wearing behaviour, the community traffic safety checkpoints used various measures to reduce helmet non-wearing behaviour among motorcycle riders who didn’t wear helmet such as lending a helmet to them and prohibiting them from passing through the checkpoint unless they came back wearing a helmet. Community traffic safety checkpoints were operated by following 3. The evaluation underlines that there was preparation of community accident prevention (97.90%); there were community checkpoints to stop risk group and reduce accidents (100%); and there was monitoring for improvement and success (96.60%). The province that is most ready for the community traffic safety checkpoint operation is Burirum. A pilot community with full capacity of community traffic safety checkpoint is more ready to operate than a pilot community with partial capacity. Number of accidents in a pilot community with full capacity of community traffic safety checkpoint is less than a pilot community with partial capacity. No accident occurred in a pilot community with full capacity of community traffic safety checkpoint which is highly ready for accident prevention activities.
