The 17th International Alcohol Interlock Symposium organised by the Traffic Injury Research Foundation (TIRF), took place with great success on 19-21 August 2018, in Austin-Texas, USA. This year’s event will feature a theme surrounding the “Versatility of Alcohol Interlocks”, meant to emphasize the potential interlocks have to deal with the increasing availability of other impairing substances that can be used in combination with alcohol. As interlock technology evolves and devices become easier to use and less intrusive, it becomes increasingly important to understand how intelligent devices can enhance road safety globally.
