Nowadays, more people believe that the best idea to improve road safety is to increase the minimum legal age of people who drives transportation. I agree, with this view and how to improve road safety method and how increasing the minimum legal age can reduce traffic accident. Firstly, modern society has high-quality equipment and a great office system that people can try to take as transportation. This could reduce car or motorbike accidents. Secondly, improve transportation system lead to safe trip for workers, student, and public. Finally, the government restricts teenagers drive cars and motorbikes is a great idea, because teenagers did not have enough experience and not natural enough. In addition, officials should promote traffic regulation for teenagers can reduce accidents.
