The Real-Driving Emissions (RDE) is a regulation set by the European Union Commission. Its main purpose is to set out the foundations for vehicle emission tests. In this paper, we present LolaPrompts, which exploits runtime monitoring to assist the drivers in performing driving scenarios that confirm to the RDE constraints. It provides the drivers with audible prompts and explanations in order to produce a valid RDE test. The purpose of our tool, LolaPrompts, is to make RDE test available for the general public and allow them to scrutinise the emission profile of their vehicles.</p
