The road safety performance of a country and the success of policy measures can be measured and monitored in different ways. In addition to the traditional road safety indicators based on the number of fatalities or injured people in road traffic accidents, complementary road safety performance indicators can be used, in relation to vehicles, infrastructure or road users' behaviour. The latter can be based on data from road-side surveys or from questionnaire surveys. However, results of such surveys are seldom comparable across countries due to differences in aims, scope, or methodology. Thus, the E-Survey of Road users' Attitudes (ESRA) was launched in 2015 aiming to collect and analyse comparable data on road safety performance at an international level, in particular on road safety culture and road users' behaviour. At the heart of ESRA is a questionnaire, conducted online, using representative samples of the national adult population of the participating countries. In its first edition, carried out between 2015 and 2017, ESRA covered almost 40,000 respondents from 38 countries across the world. This paper is based on the second edition of ESRA, which was carried out in 2018 and includes data from more than 35,000 road users across 32 countries. The objective is to present the main results of ESRA survey regarding the four most important risky driving behaviours in traffic: driving under the influence (alcohol/drugs), speeding, mobile phone use while driving and fatigued driving. The paper explores several aspects related to these behaviours, such as the self-declared behaviours, acceptability and risk perception, support for policy measures, and opinions on traffic rules and penalties. Results show that despite the high perception of risk and low acceptability of all the risky driving behaviours analysed, there is still a high percentage of car drivers who engage in risky behaviours in traffic in all the regions analysed. Speeding and the use of a mobile phone while driving were the most reported behaviours. Most respondents support policy measures to restrict the risky behaviour in traffic and believe that traffic rules should be stricter and are not being checked enough. The ESRA survey proved to be a valuable source of information to understand the processes underlying road traffic accidents. It offers a unique database and provides policy makers and researchers valuable insights into public perception of road safety.
