Abstract
Legislation for Road Safety Law is a tool for road accident prevention by controlling social behaviors and resources allocation. It is simply said that law shapes road users’ behaviors into more safety conscious behaviors and forces car producers to develop their products more regarding safety use. Despite having 3 Acts relating to road safety, Thailand has never reduced numbers of road accidents for the past three decades. This review was aimed at answering such problems and led to recommendations for improvement. According to the review, the three Thai Acts were similar to many developed countries’ in many ways; however, their limitations found in the review were: 1. the Acts partly needed amendment in line with dynamic changes of road communications, 2. lack of continuity of law enforcement and the bias of enforcement partly due to shortage of community preparation and of knowledge integration in terms of automobile engineering and financing knowledge, 3. lack of knowledge-based policy and law development, 4. Thailand’s governance of strong centralization inhibitive to law enforcement, The review recommended that contexts of the Acts be amended and related policy and law development be more accountable to social equity and efficiency.
